Frederick Longbottom ,a Thomas Cooke telescope and the formation of Chester Astronomical Society

Mr Frederick Longbottom 1850-1933 was born in Scarborough the family would move to Worcestershire where they would become hop merchants.  When he retired he was able to devote much more time to his favourite hobby, astronomy. 

He had a 6 inch Thomas Cooke and Sons telescope which he had before 1896 because he took it with him to Norway to try to observe the eclipse of the Sun. He also went on eclipse trips to Algiers in 1900 and Spain in 1905. He was at Giggleswick for the 1927 eclipse of the Sun. He helped to form the Chester Astronomical Society.

 He eventually left the north of England and settled in Boscombe in Hampshire and it was from here that Longbottom was able in early June 1928 to see the planet Mercury in the day time sky using the 6 inch telescope.

Edward Pigott 1753-1825 one of the Fathers of Variable Star Astronomy

 Edward’s branch of the Pigott family can be traced back to Adam Pigott who died in 1737, it was Adam Pigott and James Allen who in 1678 negotiated a lease from the Duke of Bedford for the construction of Covent Garden Market. Edward’ s grandfather Ralph married Alethea daughter of William eighth viscount Fairfax of Emley and owner of Gilling Castle in Yorkshire. You need to remember Gilling Castle it will come into our story later.

Ralph’s son Nathaniel was the father of Edward and was also an astronomer, but their characters were very different. Their story could resemble an astronomical soap opera.  Edward could be described as someone who was not phased by anything or anyone and was always a calm character. He never appeared to get flustered and was always very generous when working with colleagues. He also was someone who knew everyone who was anyone in the field of astronomy.

Nathaniel will be the bad guy in the story as will become apparent later. It was probably due to this that Edward was much closer to his mother Anna Mathurine De Beriot of Javingue, which was then in the Austrian Netherlands. Today this area is northwester and central Belgium and most of Luxembourg.

Edward was born possibly in Whitton in Middlesex in 1753 and went to Thomas Plunket’s school in Hammersmith and apparently learned nothing. The Pigott’s were the poor relations of the landed Fairfax’s of Gilling in Yorkshire the Pigott’s would lead somewhat of a vagrant life. They stayed in rented property in parts of Britain and on the continent either with family or friends. Edward lived with his parents in France from 1763-1771.

Edward Pigott

Edward’s father Nathaniel was also an accomplished surveyor as well as an  astronomer although it is unclear how he became interested in the subject. It was this interest in astronomy that must have impressed the young Edward. Nathaniel had purchased some of the best telescopes available at that time. Nathaniel with the help of Edward observed the partial eclipse of the Sun on August 16th, 1765, in France.

While in France they also observed the transit of Venus on June 3rd, 1769. Transits of Venus are very rare and only 7 have been observed since the invention of the telescope in 1608. A transit occurs when a planet closer to the Sun the Earth can be seen passing over the disk of the Sun. The only planets that can do this are Mercury and Venus. The last transits of Venus were in 2004 and 2012 I was lucky enough to see the 2004 transit the next will not be until 2117 and 2125.

In 1771 both Nathaniel and Edward were in Britain visiting both London and Gilling Castle which greatly impressed Nathaniel. Edward caused some interest because of his dress code, having spent a large part of his life in France he dressed in the French fashion with a large, brimmed hat, fluff collars and cuffs and long flowing coats. This very colourful style of dress was not usually seen in conservative Britain.

In 1772 the Pigott’s met representatives of the Austrian Netherlands government through various contacts they had with the Brussels Imperial Academy. They were asked to work out geographically the locations of the principal cities within the Austrian Netherlands. This was accomplished by determining the positions of buildings and towns in relation to the known positions of certain celestial objects.

In 1773 Lord Fairfax of Gilling died and his property passed to his elderly and unmarried daughter, Lady Anne Fairfax. It was her chaplain John Bolton who managed the estate but in 1775 when Nathaniel Pigott settled at Gilling that the problems really started. Nathaniel Pigott wanted to manage the estates of his cousin, with a view to owning the estate. He managed to persuade her to go to London while she was unwell and let him run the estate. He made her sign some articles of agreement which would give Pigott £250 per year to manage the estate. Nathaniel was not a particularly nice person, and he would make life difficult for anyone who got in the way of his plans. In this case owning the Gilling Castle Estate. He did his very best to discredit John Bolton who was a great supporter of Lady Anne Fairfax at  every opportunity.

It was at this time that the Pigott’s stayed briefly with another relative Lady Widdrington at Wickhill House near Stow on the Wold, Gloucestershire. They then moved to another of the Pigott estates and to Frampton Hall near Llantwit Major in Glamorganshire where an observatory was built. The observatory was lavishly equipped with no less than 4 telescopes plus other astronomical equipment for recording the positions of the stars and clocks for working out the time for their locality.

It was now that Edward’s career in astronomy would really begin having assisted his father in making observations of the night sky while in France, he had acquired a good knowledge of the sky and how to make and record observations.

However bizarrely they set to work not on an astronomical problem but on a problem on the width of the River Severn. The maps that were produced at the time indicated the width of the river between Llantwit and Watchet on the Somerset shore was between 20 to 21 miles. The Pigott using their knowledge of the positions of the stars and mathematics worked out that the River Severn at this point was only 13 miles wide. This went a long way to explain why some many ships were running around in the area.

Edward now turned his attention to astronomy and to the stars,  while at Frampton House he discovered a nebula in the constellation of Coma Berenices.

 

Coma Berenices or Berenices Hair is a faint constellation with no bright stars.  The constellation can be found when the sky is clear but if there is any haze around, the area will appear blank.

 

Edward Pigott made this discovery on the 23rd of March 1779 twelve days before the German astronomer Johann Bode saw the nebula. This nebula that Pigott had discovered was in fact a spiral shaped galaxy lying at around 17 million light years from Earth.

The galaxy the Pigott had discovered is known today as the Black Eye Galaxy, it is so named because there is a lot of dust between us and the central part of the galaxy which is very bright but the dust blocking the light makes it look as if the galaxy has a black eye.

In 1781 the Pigott’s moved to York there was great expectations of Nathaniel taking over the running of what was left of the Gilling estate. They moved to a house in Bootham near Bootham Bar. They built an observatory consisting of two octagonal rooms on top of each other. The observatory was 14 feet in diameter and was completed in May 1781 it was one of the most well-equipped observatories in the country.

Edward wrote to William Herschel who was a good friend regarding his move to York, however in March 1781 Herschel had stunned the astronomical world when he discovered the planet, we now call Uranus from his home in Bath using a telescope that he made himself. It was completely unexpected, there were five known planets, the Sun and Moon which made the mystical number of seven. The discovery made Herschel the most famous astronomer of this time.

Edward’s connections in the world of science were about to be used to the fullest as it was by good fortune that in 1781 John Goodricke would join him in York and their astronomical adventures were about to begin. They had both already been observing a star in Perseus call Algol or the Winking Demon.

Most of the star names are Arabic and Algol means the winking demon. The star varies in brightness so is classified as a variable star. This variability was discovered by the Italian astronomer Montanari in 1669. The name Algol or winking demon suggests that maybe the Arab astronomers of a 1,000 years ago thought it varied in brightness although we have no proof of this.

Edward Pigott and John Goodricke would become the fathers off Variable Star Astronomy. This was because they were the pioneers in this field of astronomical research into variable stars. They worked together in York between 1781 -1786 until the early death of Goodricke at the age of 22. Goodricke was deaf but there was absolutely nothing wrong with his thinking processes.

John Goodricke observed from the Treasurer’ House in York and Edward Pigott from his observatory in Bootham in York around about a quarter of a mile away.

They noticed that the changes in light variation were very regular. They noted that it changed brightness in just under every three days before returning to normal brightness. The cycle then repeated itself regularly. The whole cycle could be followed by the naked eye. In other words, no telescope was needed to follow the light changes in the star.

It appears as if both Goodricke and Pigott suggested that there were two objects orbiting each other and eclipsing each other and causing the light changes in the Algol. They were correct. It would be about 100 years later that astronomers could prove their theory to be correct.

Astronomers today use this same principle when they notice tiny changes in light from stars suggesting that there might be an object or planet passing in front of the star and therefore orbiting that star. Of over 4,000 exoplanets or planets that are known to orbit other stars around 1,000 have been used using this method.

Goodricke and Pigott were over 200 years ahead of their time with their thinking.

Although Goodricke gets most of the praise it was a joint effort, Pigott because of all his astronomical contacts made sure that the work that Goodricke was published.   Goodricke was only 19 years old and unknown while Pigott through his contacts knew everyone worth knowing in the field of astronomy. Pigott seemed to be quite content for Goodricke to get the praises.

He encouraged Goodricke to send his paper to London where in 1783 the paper on the star Algol was read to the Royal Society. It bought him instant recognition throughout the astronomical world and would lead to him being presented with the Copley Medal the most prestigious award that could be given to a scientist.

They continued to observe the stars and in November 1783 Edward Pigott would become the first person to discover a comet from York and the first Englishman to have a comet he discovered named after him.

September 10th, 1784 would become a night to remember in York when both Edward Pigott and John Goodricke each discovered a new variable star. Edward Pigott discovered the star eta Aquila varied while John Goodricke discovered the variability of beta Lyra. Until this point in time only 5 variable stars were known to astronomers, here on one night a further two were added to that list.

This would be Pigott’s last astronomical discovery in York, in 1785 he left for a two-year visit to France and while he was away, John Goodricke died. On his return he stayed in York until 1793 when his mother died, and he then moved to the city of Bath. He them returned to studying the night sky. In 1795 he would discover two more variable stars, R Corona Borealis and R Scutum.

I just need to finish off the story of Gilling Castle because Lady Anne Fairfax died in 1793 with Nathaniel Pigott becoming owner of Gilling Castle an act or Parliament was needed to allow the Pigott family to take the Fairfax name and inherit the castle. This was done in 1802 and Nathaniel decided that his second son Charles Gregory should inherit Gilling Castle rather than his eldest son Edward. Nathaniel would die in 1804.

In 1802 during the treaty of Amiens between Britian and France Pigott returned to France to meet friends. This was possibly not the best thing to do because in 1804 war broke out again and he was placed under house arrest in Fontainebleau. He was released in 1806 after British and French scientists had petitioned the French government for his release. He was given safe passage back to Calais under instructions by Napoleon.

On his return to England, he carried on with his astronomy and a new passion the study Phycology or Seaweed a subject in which he became something of an expert.

He made some observations of the great comet of 1811 but as he said to his great friend Sir William Herschel in 1821, he was getting older and finding it more difficult to move around.

Edward Pigott died in the 27th June 1825 in the city of Bath, in accordance with his wishes his body was transported to Bridlington where he was to buried next to his mother in Bridlington Priory.

Edward Pigott and the discovery of R Scutum in 1795

This year is the 200th anniversary of the death of Edward Pigott one of the ‘Fathers of Variable Star Astronomy’ this was a title I gave him and the deaf astronomer John Goodricke who between 1781-1786 would make incredible advances in the discovery and study of the branch of astronomy we know of today as variable stars.

 Pigott was born in Whitton, west London in 1753 and died on June 27th, 1825. His life would make an incredible soap opera story, but much more of that later.

Edward Pigott


Here is another of a series of highlights from his incredible career.

The year 1795 was a busy one for Edward Pigott and his search for variable stars. He had already identified the star R Corona Borealis to be a variable star and now he was about to discover another one. R Scutum.

In the 18th century at the time of Edward Pigott this star was in the constellation known to him as Sobieski ‘s Shield. This constellation is a modern constellation compared to the ancient Greek ones. It was Johannes Hevelius the Polish astronomer who created the constellation in 1684 to commemorate the victory of King John Sobieski over the Ottoman Empire at the Battle of Vienna in 1683. Today the constellation is simply known as Scutum the Shield.

Pigott said that there are very few stars in the constellation and that this star was not recorded by Hevelius. This would suggest that Hevelius created the constellation the star was at its faintest and therefore not seen by Hevelius.

Looking at his notes he first saw R Scutum in September 1795 and quickly realised that it changed in brightness. He believed it had a period of around 63 days, a period he would have worked out towards the end of 1795. and varied in brightness between magnitude 5 and magnitude 7.8. Unlike R CrB which faded from view when at its faintest Pigott could follow this star through its cycle of light changes.

Pigott would observe R Scutum through until October 1801. I assume that because he could follow the complete cycle it was easier to study than R CrB which was far more irregular in nature and at its faintest disappeared.

Today astronomers recognise R Scutum as a RV Taurus type of variable star. Strangely though R Scutum is brighter than the named star of this type. These stars vary in a regular and irregular way and are not very well understood. Astronomers today are still trying to work out makes these stars tick. 

Astronomers today know that R Scutum varies between magnitude 4.2 to 8.6 so Pigott’s estimate of magnitude 5 and 7.8 was close to modern day estimates. However, one area that Pigott got wrong was the length of time it took the star to vary in brightness, he thought it was 63 days we know today it is around 146 days

Edward Pigott and the discovery of R Corona Borealis in 1795

This year is the 200th anniversary of the death of Edward Pigott one of the ‘Fathers of Variable Star Astronomy’ this was a title I gave him and the deaf astronomer John Goodricke who between 1781-1786 would make incredible advances in the discovery and study of the branch of astronomy we know of today as variable stars.

 Pigott was born in Whitton, west London in 1753 and died on June 27th, 1825. His life would make an incredible soap opera story, but much more of that later.

Edward Pigott

Here is another of a series of highlights from his incredible career.

Following the death of his friend and colleague John Goodricke in York in 1786, Edward Pigott finally decided to leave York and move to the city of Bath in1793. He would soon start looking for variable stars.

One of the stars he was following was in the constellation of Corona Borealis the Northern Crown. This star which we recognise today as the star R Corona Borealis (RcB) is the prototype star of a group of only about 150 stars of this type. 

Pigott started observing the star from July 1783 while he was in York, by the spring of 1795 he was able to confirm that it varies in brightness. He would continue to monitor the star through 1796. When at its maximum brightness it was of the 6th magnitude just about visible to the naked eye under the very best of condition but when at its faintest it was invisible in Pigott’s telescope. Pigott identifies this period of light variation taking around ten and a half months.

Pigott stated that although it was not in the catalogue of John Flamsteed of 1725 it  was listed in the star atlas of Johann Bayer from 1603 as being of the 6th magnitude. This would suggest that it was at its brightest when Bayer produced his star atlas.

Pigott noted that when R CrB was either fading or brightening it did so at an uneven rate. This was different to the stars Algol and eta Aquila that he had observed, the light curve on a graph of Algol and eta Aquila were very smooth while that of R CrB was more jagged. He was very curious to the fact that it disappeared for a period before re appearing. He believed that further observations would be needed to confirm the period of ten and a half months for this star was correct or not.

Today astronomers know that the star will remain at it brightest for many months or even years before fading in brightness. It will then return over a long of time period to its brightest. Pigott was wrong in his calculation that R CrB varied over a period of about ten and a half months. This was simply since he was not able to observe the star for a long enough period to see how irregular the light variations were.

As I mentioned R CrB is the prototype star for this small group of stars. The cooling is caused by a cloud of soot which forms around the star from the condensation of carbon rich dust in the star. As the dust cloud forms the star is masked by this cloud of dust, the brightness of the star is affected, and we see the star fade in brightness. Then when the cloud of soot clears R CrB returns to normal brightness.

R CrB is an old star and is only one of two stars in this class that can be seen with the naked eye the other is RY Sagittarius. All the other stars in this class need telescopes to follow their cycles.

Edward Pigott discovers a new variable star in the constellation of Antinous now Aquila


This year is the 200th anniversary of the death of Edward Pigott one of the ‘Fathers of Variable Star Astronomy’ this was a title I gave him and the deaf astronomer John Goodricke who between 1781-1786 would make incredible advances in the discovery and study of the branch of astronomy we know of today as variable stars.

 Pigott was born in Whitton, west London in 1753 and died on June 27th, 1825. His life would make an incredible soap opera story, but much more of that later.

Edward Pigott


Here is another of a series of highlights from his incredible career.

I have already indicated how good an observer Edward Pigott was, here is an example of his patient watching of the skies. On September 10th, 1784, he would discover a new variable star, on the same night John Goodricke would also discover new variable star. Two new variable stars in one night, this certainly was a night to remember in York. Up until now astronomers only knew of 5 other variable stars.

I would like to concentrate on Pigott’s discovery. Since July 17th, 1783, Pigott had been observing the star we now call eta Aquila. Interestingly it was not always in the constellation of Aquila the Eagle.

The constellation of Antinous had been known since ancient times when the Greeks saw it as Ganymede a youth bought to his lover Zeus by the eagle Aquila. The Romans then changed it to represent a friend of the Roman emperor Hadrian.



The constellation of Antinous was represented by stars immediately below Altair the brightest star in the constellation of Aquila the Eagle. Eta marked the head the rest of the outline are represented by the star’s sigma, theta, iota, kappa, lambda, nu and delta.

The star that Pigott was observing was eta Antinous, now it is eta Aquila as the stars that made up Antinous were by the later part of the 19th century incorporated in the constellation of Aquila.

The idea of using Greek letters to identify stars in a constellation was introduced by the German astronomer Johann Bayer in 1603. In theory alpha is brightest then beta all the way down to omega which is the 24th and last letter of the Greek alphabet. Sometimes this works and sometimes it does not. If you look at the brightness of star in a constellation alpha is not always the brightest star.

Pigott saw that it varied in a regular fashion rather like Algol in Perseus. With eta around every 7 days the stars faded and then returned to its normal brightness.  Also, like Algol the changes in brightness could be observed with the naked eye, no telescope was needed. He continued to observe the star until December 1784.

In concluding that eta Antinous was like Algol, Pigott was wrong. However, we can hardly blame him for concluding what he did. They simply did not know what was going on inside stars. Both Pigott and Goodrick were taking the view that any star that changed in brightness in a regular way must have an unseen companion going around it.

Today we know that eta Aquila to give its modern designation is a variable star that varies in a very regular way. This is due not to some unseen companion orbiting it but to an internal mechanism. Astronomers have classified eta Aquila as a cepheid variable, these are stars that are used by astronomers to measure distances in space. The first cepheid variable delta Cepheus was discovered in October 1784 by you guessed it, John Goodricke.

This would be Edward Pigott’s last major astronomical discovery in York. In 1785 with his father Nathaniel, they planned to be away for around two years going back to France.  One area that Pigott did want to concentrate on was looking at stars that he called suspect variables. These were stars that needed more observations to confirm if they really did vary in brightness.

His next major contribution would be in 1795 after the death of John Goodricke who died on 1786 and this observation would be made not from York but from the city of Bath.

Edward Pigott and the comet that was discovered in York in 1783

This year is the 200th anniversary of the death of Edward Pigott one of the ‘Fathers of Variable Star Astronomy’ this was a title I gave him and the deaf astronomer John Goodricke who between 1781-1786 would make incredible advances in the discovery and study of the branch of astronomy we know of today as variable stars.

 Pigott was born in Whitton, west London in 1753 and died on June 27th, 1825. His life would make an incredible soap opera story, but much more of that later.

Here is another of a series of highlights from his incredible career.


Edward Pigott has the distinction so fa at least of being the only person to have discovered a comet from the City of York. He is also the first Englishman to have discovered a comet and have it named after him.

It was on November 19, 1783, when he made his discovery. It would be seen a few days later by all the great astronomers of the period including William Herschel and Charles Messier.

It was faint in the constellation of Cetus the Whale when Pigott saw the comet through the Dollond telescope in his father’s observatory in Bootham in York. Pigott described the comet looking like a small nebulous patch. It was too faint to be seen with the naked eye.

The comet was observed only observed for about a month until it became too faint to be seen.  Pigott last saw the comet on December 3rd, 1783, and by Charles Messier on December21st. After this the comet was lost from view.

As the comet was not followed for very long and there were very few observations it was difficult to be able to say when it might be seen in the sky again. Although many searches for comet Pigott were undertaken it seemed to have simply disappeared.

To the end of his life Edward Pigott had no idea what happened top his comet. The story of his comet then jumps for the 18th century to the 21st century.

In January 2003, 220 years after it was first discovered that comet Pigott was re discovered.  The Lincoln Near Earth Asteroid Research (LINEAR) project found a ‘new’ comet with their telescopes outside of Socorro, New Mexico.   The comet was designated Comet C/2003 A1 (LINEAR) a suggestion was made that it might be a return of long-lost Comet Pigott. Unfortunately, it was not possible to make a definite link between the 2003 LINEAR comet and Pigott’s 1783 discovery.

On the night of September 10th, 2009, Rich Kowalski of the Catalina Sky Survey was surveying the sky for unknown comet and asteroids when he came across a possible new comet. You have guessed it; it was none other than Comet Pigott. When discovered in 1783 the comet was bright enough to be seen in a small telescope, today a powerful telescope is needed as the comet is very fain at around magnitude 17. Today we know that the comet has an orbital period of around 6 years.

In the 242-year period that we have known of this comet it has changed its name three times from comet Pigott to comet Pigott-LINEAR, to comet Pigott-LINEAR-Kowalski. We cannot say that of many other comets.

Edward Pigott may have been one of the Fathers of Variable Star Astronomy but he was also the first English person to have a comet named after him and the only person until now to have discovered a comet from York.

This was just another of his incredible astronomy discoveries.

Edward Pigott, John Goodricke and the Winking Demon Star

 This year is the 200th anniversary of the death of Edward Pigott one of the ‘Fathers of Variable Star Astronomy’ this was a title I gave him and the deaf astronomer John Goodricke who between 1781-1786 would make incredible advances in the discovery and study of the branch of astronomy we know of today as variable stars.

 Pigott was born in Whitton, west London in 1753 and died on June 27th, 1825. His life would make an incredible soap opera story, but much more of that later.

Edward Pigott


Here is another of a series of highlights from his incredible career.

There is a star in the constellation of Perseus, he was the hero who rescued the princess Andromeda from the Kraken or sea monster. He had just killed the Medusa a creature so horrible that if you looked at it you would turn to stone the medusa’s hair was made from snakes.

In the sky the constellation of Perseus is seen holding a sword in one hand and the head of the medusa in the other. The star that marks the eye of the medusa is called Algol.


Most of the star names are Arabic and Algol means the winking demon. The star varies in brightness so is classified as a variable star. This variability was discovered by the Italian astronomer Montanari in 1669. The name Algo or winking demon suggests that maybe the Arab astronomers of a 1,000 years ago thought it varied in brightness although we have no proof of this.

Edward Pigott and John Goodricke would become the fathers off Variable Star Astronomy. They worked together in York between 1781 -1786 until the early death of Goodricke at the age of 22. Goodricke was deaf but there was absolutely nothing wrong with his thinking processes.

The records are a little scare, but it is believed that both Pigott and Goodricke started observing Algol sometime in late 1781. We know they were both constantly observing the star in 1782. John Goodricke observed from the Treasurer’ House in York and Edward Pigott from his observatory in Bootham in York around about a quarter of a mile away.

They noticed that the changes in light variation were very regular. Goodricke noted that it changed brightness in just under every three days before returning to normal brightness. The cycle then repeated itself. The whole cycle could be followed by the naked eye. In other words, no telescope was needed to follow the light changes in the star.

It appears as if both Goodricke and Pigott suggested that there were two objects orbiting each other and eclipsing each other and causing the light changes in the Algol. They were correct. It would be about 100 years later that astronomers could prove their theory to be correct.


Astronomers today use this same principle when they notice tiny changes in light from stars suggesting that there might be an object or planet passing in front of the star and therefore orbiting that star. Of over 4,000 exoplanets or planets that are known to  orbit other stars around 1,000 have been used using this method.

Goodricke and Pigott were over 200 years ahead of their time with their thinking.

Although Goodricke gets most of the praise it was a joint effort and a very major part that Pigott did play in was in getting Goodricke’s results published.  Goodricke was only 19 years old and unknown while Pigott through his contacts knew everyone worth knowing in the field of astronomy. Pigott seemed tom be quite content for Goodricke to get the praises.

He encouraged Goodricke to send his paper to London where in 1783 the paper on the star Algol was read to the Royal Society. It bought him instant recognition throughout the astronomical world and would lead to him being presented with the Copley Medal the most prestigious award that could be given to a scientist.

The character of Pigott was such that he did not mind that Goodricke got most of the attention. Even today Pigott is often seen in the shadow of Goodricke when they worked on joint projects together.

Edward Pigott and the discovery of the Black Eye Galaxy

 This year is the 200th anniversary of the death of Edward Pigott one of the ‘Fathers of Variable Star Astronomy’ this was a title I gave him and the deaf astronomer John Goodricke who between 1781-1786 would make incredible advances in the discovery and study of the branch of astronomy we know of today as variable stars.

 Pigott was born in Whitton, west London in 1753 and died on June 27th, 1825. His life would make an incredible soap opera story, but much more of that later.


Here is the first of a series of highlights from his incredible career.

In 1777 with his father Nathaniel, Edward Pigott moved to Frampton House near Llantwit Major in Glamorganshire one of many of the Pigott’s estates. They had a rather impressive observatory there with several telescopes. These included a 6-foot long Dollond, a Watkins with a 2.5 inch lens and a 2.5-foot long telescope by Heath and Wing with a 5 inch mirror.

Edward although only 24 years old was already an experienced observer having helped his father make observations while living in France.

Since moving to Frampton House Pigott had been making observations of the night sky whenever he could.  On March 23rd, 1779, Edward Pigott was observing the constellation of Coma Berenices when he discovered what he called a nebula. It was faint at magnitude 9.4 which is way below naked eye visibility. This today we know is a galaxy which is called the Black Eye galaxy.

The Black Eye galaxy is around 24 million light years from Earth, you would need a powerful pair of binoculars or a small telescope to see it. Then it would only appear as a small dot in the sky. If you go online, you will see some amazing photographs of the galaxy. There is a lot of dust in front of the galaxy which gives the impression of a black eye hence its name.


The German astronomer Johann Bode also saw it but 12 days after Pigott. In one of those strange twists of fate Pigott’s results were not published by the Royal Society until 1781 after the report from Bode. Initially Bode was credited with the discovery.

As at the time Bode was a very well-known astronomer and he had discovered many objects that would end up in the messier catalogue, he was initially credited with the discovery. In fact, many references through the late 20th century incredibly still credited the discovery to Bode.

In 1780 the French astronomer Charles Messier saw it. He was looking for comets but kept finding lots of little smudges in the sky which he confused with comets.

Messier discovered around a dozen comets none of them very bright but his list of non-comet objects, his Messier list of 110 objects is still used by astronomers today. The Black Eye galaxy is number 64 on his list. Hence you will often see the galaxy that Pigott discovered recorded as M64

Today the records have been put straight, and Edward Pigott is officially credited with discovering this galaxy in Coma Berenices.

Although he did not realise it at the time this was the first of a series of major astronomical discoveries that would be made by Edward Pigott.

A Thomas Cooke telescope at the Yorkshire Exhibition at Leeds in 1875

Mr John Mc Landsborough 1820-1900 of the exchange, Bradford exhibited a large equatorial telescope made by Thomas Cooke and Sons of York at the Yorkshire Exhibition at Leeds in June 1875. Unfortunately I do not know the size of this telescope.

 

John Mc Landsborough was a civil engineer, born in Scotland his family moved to Otley in Yorkshire where the young John was educated at the Grammar School in Otley. He later moved to Bradford where he established a meteorological station. He was always interested in astronomy and apart from the Cooke telescope he also had a reflecting telescope made by Browning

Sale of a large Thomas Cooke telescope in 1871

The great refractor by Thomas Cooke and Sons oy York, which was shown at the International Exhibition of 1871 was sold by auction by Messrs Stevens of King Street, Covent Garden for about £750.

 

The instrument which had every modern appliance, and was one of the most complete ever turned out by the celebrated instrument makers was of 10 inches clear aperture and was originally priced at £1,200, but owing to the rise in wages and materials would now be charged much more. The purchaser was Mr Henley, the telegraph engineer.

 

William Thomas Henley was a submarine cable maker in Greenwich. He set up the Persian Gulf Cable which was 1,651 miles long. The success of which allowed him to gain many more contracts.

The best time to Mercury in the evening sky this year

Despite what we have been hearing in the press regarding all the planets on view in the sky we are now approaching the very best time to look for the most elusive of the planets, Mercury. It’s the closest planet to the Sun which makes it difficult to locate.


On the nights t of March 7th and 8th look to the west after sunset, you will see the bright white dot of Venus you can’t miss that, look below Venus which will act as a fantastic guide and you will see another bright dot in the sky. It will look a little bit pinkish in colour. Its not as bright as Venus but if you are going to see Mercury in the evening sky this year this is your best chance.

Thomas Cooke telescopes for school in Carlisle in 1857

 In February 1857 William Day of Carlisle who was headmaster at the Christchurch Boys School in Carlisle purchased a 4.25 inch portable equatorial telescope. As this was early 1857 it could still be a Thomas Cooke of York telescope rather than a Thomas Cooke & Sons of York, because it was around this time that the company changed its name. 

He also  in early 1858 purchased a smaller 3.5 inch telescope also from Cookes.

The Darlington Telescope a Thomas Cooke telescope

 

The story of the telescope begins in 1890, when the vicar of Eryholme, in Richmondshire North Yorkshire the Reverend Walter Stewart, had it installed in his home, Ellcott House, in Hurworth near Darlington.

 

It was "a 5-inch equatorially-mounted refractor" built by T Cooke and Sons of York and London.

 

It cost £374, and was regarded by one and all as a very fine instrument , a vast amount of money at the time.

 

In 1904, Mr Stewart, who was born in Hurworth, was offered a new living in Longley, Gloucestershire. Because Longley is a long way, the telescope had to remain, and so Mr Stewart offered it to Darlington council for about £130.

 

It seemed natural to place the telescope at the new technical college in Northgate, built in 1896, but the college was still £2,163 in debt and the councillors were in no mood to increase its overdraft for the sake of a telescope.

At the last minute, 29 of the town's leading citizens emptied out their pockets and scraped together enough money to prevent the telescope being sent to the saleroom.

 

They formally presented it to the town on November 8, 1904, and the following year it was set up in the college's back yard.

 

But its view of the skies was not good and it was planned to move it to the college roof for "an uninterrupted view of the heavens".

 

But an astronomical advisor reported: "If the telescope is to be regarded as a pastime then that position would be satisfactory enough, but if a scientific use is to be made of the instrument the position is absolutely unsuitable. The ordinary tram and other forms of traffic set up a great deal of vibration."

 

North Lodge Park, next to the college, was dismissed as a site because town centre smoke would have obscured the heavens, so a site in South Park, next to the bowling green, was chosen.

 

The telescope was installed in December 1906 in its wooden, revolving observatory. Students of the skies had to pay 6d each, and inform the park superintendent if they intended to arrive after the park gates were locked for the night. 

 

In February 1908, Professor Dixon, one of the telescope's supervisors, even started an astronomy class at the technical college to make use of the instrument.

But in October 1910, the class was discontinued because it had no students.

In 1912, it was reported that "very little use is being made of the telescope", and by 1919 there was even less.

 

In January 1931, the Darlington and Stockton Times reported: "The telescope is seldom used now; in fact very few people know of its existence."

 

At the request of Darlington Grammar School, which is now the Queen Elizabeth Sixth Form College, the telescope was removed to playing fields off Abbey Road.

There, its 100 ft high observatory was not popular with residents of Westbourne Grove.

 

In February 1951, the observatory was broken into, but police recovered the stolen equipment a couple of months later.

 

In 1979, Barry Hetherington, then chairman of the Cleveland and Darlington Astronomical Society, reported that the telescope needed a major overhaul.

 

In 1992, there was a fire in the wooden observatory and a lump of melted metal was sold as scrap. Six months later, someone seems to have realised that this lump was in fact the remains of the Darlington Telescope.

 

Later that year, it was reported that the base, the internal workings and the observatory wheels had survived the blaze and were being kept in a metal container.

 

There was some vague talk about them one day being included in a new, £50,000 telescope, but that that idea was quietly eclipsed.

Thomas Cooke telescope to Manchester in early 1860s

 Eddowes Bowman 1810-1869 was born in Nantwich in Cheshire and although he considered going into an engineering profession but his career took him into the field of classical literature. 

He became chair of Greek and Latin Classics and Greek and Roman History in Manchester New College. It was also at this time that he developed an interest in natural science. This included astronomy. 

In the early 1860s he purchased a 7.25 Cooke refractor in a specially constructed observatory. I do not know if the observatory was built by Cookes. Due to his many other interests it appears as if the telescope was little used. He died at Victoria Park Manchester.

 Born November 1810 died July 10th 1869

The Moon, Jupiter and the Seven Sisters

The Moon is going to glide past the Seven Sisters or Pleiades and Jupiter between March 4th and March 6th . The Pleiades can be seen as a fuzzy patch in the sky. It is a cluster of stars. On a good clear night seven stars can be seen. I usually can only see 5 or 6 stars. 

On March 4th the Moon will be just below the Seven Sisters while on the 5th it will be above the Seven Sisters and to the right of Jupiter. By March 6th the Moon will be above Jupiter

T W Backhouse, two comets and a Cooke telescope in 1892

On the 27th September 1892 about 15hrs 30 mins GMT comet Brooks (c1892) had a tail 10 degrees long, pointing at an angle of 280 degrees this was observed with his 4.5 inch Thomas Cooke telescope

 At the later part of September Swift’s comet (a1892) was still a conspicuous object seen with the  4.5 inch Cooke telescope. Observations on several nights showed that it not only has  a faint tail- at position angle 260 degrees on the 24th September at 8hrs and 30 mins, when I observed it to be certainly 11 degrees long, and suspected it to 21 degrees- but that also there was an elongation nearly in the opposite direction.
