A Cooke in the Himalayas

Transit of Venus

This station (Roorkee) is in fact a contribution made by the Government of India at the suggestion of Colonel Tennant B.E, ( Bengal Engineers), who in and since 1865 has rendered valuable aid in the observations of many interesting astronomical phenomena visible in Indian territory, especially the total eclipse of 1868 and 1871.

The suggestion of Colonel Tennant was at once warmly taken up by the viceroy in conjunction with the home government with a view to their future use in subsequent inquiries. The instruments sent out by Colonel Strange, of the India Stores Department are of the utmost precession and delicacy.

The temporary observatory erected by Col. Tennant at Roorkee, the seat of the Indian Civil Engineering College at the foot of the Himalayas, now contain a refractor of 6 inch aperture made by T Cooke & Sons York.

Colonel Tennant from Roorkee says that during the transit one hundred photographs of the planet had been taken.

Probably if nothing else had been done, this would have secured to England an honourable place in the record of investigations.

Solar prominence seen from India with a Cooke

 

On February 18th 1908 Mr Evershed at the Solar Physics Observatory, Kodaikanal, South India using a 6 inch Thomas Cooke & Sons telescope took a series of photographs of a solar prominence. 

The remarkable appearance of this kind of prominence has seldom been recorded. 20 photographs were taken with 14 being reproduced here.

Visual observations were also made which indicated a moderately bright mass of prominences

A Cooke for Calcutta

 

In 1903 Thomas Cooke & Sons of York supplied a 4.5 inch telescope to the Government Observatory in Calcutta, India. The head of the observatory was Mr Evershed, Attached to the telescope was a 5 inch Camera also supplied by Cookes.

The telescope was mounted on a Cooke iron pillar which were housed in a shed. This shed was mounted on wheels and rails that allowed it to be moved when the telescope was to be used.

Comet Coggia seen through 25 inch Cooke telescope at Gateshead

 

On July 12th 1874 Robert Newall and Norman Lockyer observed comet Coggia using the Thomas Cooke & Sons 25 inch telescope.

The observations were made at Newall’s observatory at Gateshead. The 25 inch was at the time the largest telescope in the world.

Occultation by Jupiter seen from Canada with Cooke Telescopes

 

Attempts were made on May 22nd 1896 at several points across Canada to observe the occultation of a 9th magnitude star in Cancer by Jupiter.

At the Toronto Observatory Mr F L Blake using the Cooke 6 inch refractor found the planet was too low in the sky for first class seeing, although the night was clear.

Dr J C Donaldson of Fergus Ontario using a 3.25 inch Cooke & Sons refractor obtained a glimpse of the star, but the nearness to the horizon made observing very difficult.

It is not known if any other observers further to the west observed the occultation.

An old Cooke in Toronto

 The University of Toronto’s David Dunlap observatory at Richmond Hill near Toronto, Canada today houses a 74 inch Grubb Parsons reflector that was installed in 1935. However there was a much older observatory in Toronto.


This was the Toronto Magnetic and Meteorological Observatory at the University of Toronto which housed a 6 inch Thomas Cooke & Sons telescope that was installed in 1880. The Cooke was used in particular for the study of sun spots in conjunction with magnetic measurements made at the observatory. I believe that the Cooke may have been used until around 1910.
