A little ramble through You Tube Aquila the Eagle

 https://youtu.be/N8GQAFAY6q0

Aquila the Eagle is one of the original 48 Greek constellations. Altair often represents a bird in mythology that was a companion to Jupiter and often carried his thunderbolts.

The constellation is one of the most prominent in the sky. Altair is one of the summer triangle of stars that grace our sky during the summer months. The others are Vega and Deneb. Altair is the most southerly of the triangle stars.

There are 88 constellations in the night sky, 48 are regarded as classical in that they were known to the astronomers living thousands of years ago. The other 40 are called modern. These were added during the 1500s, 1600s and 1700s.Many are in the southern hemisphere which were unknown to Europeans.

People tend to use the Greek myths and legends with the classical constellations; the modern ones have no myths or legends attached to them.

Most of the star names used are Arabic

A little ramble through the Astronomical Register March 1864 - companion of Procyon

 Astronomical register March 1864 

COMPANION OF PROCYON. 

TO THE EDITOR OF THE ASTRONOMICAL REGISTER. Sir, I beg, through the medium of the Register, to call attention to a severe but convenient test - object. I refer to the small star in the same field and immediately following Procyon, and nearly on the same parallel. For some months past I have suspected the star to be double; and on Tuesday last, February 9, succeeded in separating very distinctly the com- ponents with my silvered - glass speculum of twelve inches ' aperture. They seem to be 9'5 and 9.8 magnitude stars respectively, and Mr. Knott, who has since seen them with his refractor, tells me he thinks their angle of position is about 200 ° .

At some distance north preceding, is a 14th magnitude comes, which, with the close pair, form a most delicate triple combination.

Can the close pair above referred to be the star mentioned by the Rev. T. W. Webb in his Celestial Objects for Common Telescopes, in connection with Procyon? He calls it a curious variable star, about 2.5’ distant, very nearly 8 mag. Smyth, 1833; 9 mag. Fletcher, 1850; missed by Bond 1848, Fletcher 1853, Hind 1853-4-5 .

 

General Cemetery, Birmingham, 

Feb. 15, 1864 

I am, Sir, yours faithfully, FREDERICK BIRD.

Cooke Telescope Tales - Leeds Astronomical Society visit Cooke factory in York in1920

On Saturday afternoon October 9^th 1920 members of the Leeds Astronomical Society of which Mr David Booth is president and others visited the works of Messrs Cooke and Sons Ltd Bishophill, York where an interesting and instructive time was spent. 

During their tour around the works they saw how lens are ground down and polished and how various instruments are used and adjusted. 

Among the other things pointed out were various parts of the 18 inch telescope for Brazil. In the show room there were various telescopes including one made by Mr Cooke in 1850.

 The visitors were surprised to find that in York there were such large and extensive works equipped with the various modern and accurate machines capable of making the most precise scientific instruments for the exacting demands of today.

A little ramble through 19th century astronomy - The Inter Mercurial Planet in 1877

 Nature January 25^th 1877

The Inter Mercurial Planet

In M. Leverrier’s last communication to the Paris Academy on the planet assumed to exist within the orbit of Mercury, it was mentioned that, with the elements adopted, or very similar ones, a solar conjunction would occur on March 22, and a transit over the sun’s disc was possible though uncertain.

A close examination of the disc is therefore recommended on March 22 and 23, and there is reason to believe that observers in widely differing longitudes are prepared to undertake it.

If no transit should occur, eight or nine years may elapse before one is possible at the spring node.

A little ramble through Pyxis the Compass

 Pyxis the Compass is the smallest and least impressive of the four parts into which the constellation Argo Navis the ship was divided into in the 1750s by the French astronomer Lacaille. The other sections are Carina the keel, Puppis the poop and Vela the sails.

There are no objects of particular interest to naked eye observers or indeed to users of binoculars even though the constellation lies in the Milky Way.

The brightest star is alpha at mag 3.7 which is a B class giant with a surface temperature of 22,000’C and is 880 light years away.

T Pyx is a recurrent Nova that has erupted more times than any other Nova. T Pyx erupted in 1890, 1902, 1920, 1944, 1960 and 2011. It lies between beta and lambda. It usually brightens from mag 15 to around mag 7.0 meaning that at maximum it can be seen with binoculars.
