The Godlee observatory is situated on the roof of The University of Manchester.
The
meeting rooms are on floor G of the Sackville Building, University of Manchester,
Sackville Street, Manchester. They are situated directly under the observatory
which is accessed via a spiral staircase climbing up past the massive telescope
pier supported by immense steel I-beams that span the observatory tower. The
main. high-ceiling octagon room, with its superb views across the city from
the tall windows in six of its eight walls, houses the library which contains
a large collection of astronomical reference books (some going back to the 19th
century) and journals. The MAS are fortunate in possessing a complete set of
Journals of the British Astronomical Association dating from 1890. The library
also includes several books presented to the Society by their authors.
The octagon room is an open
forum for informal discussions every Thursday evening throughout the year (except
the winter session lecture evenings in the currently held at the MMU in the
John Dalton Building) where groups of like-minded people can talk about current
astronomical topics and events. It is also the room used for telescope making
classes. Mirror making is a popular activity thanks to Mr Steve Hodgkinson and
complete telescopes are constructed for subsequent loan to members of the Society.
Several members assembled electronically controlled, Scotch-type, camera drives
for wide field astrophotography.
The octagon
room is also the venue for meetings of the
North West Group of Astronomical Societies and other visitors to
the Society. Over the years these have included a party of Russian delegates
to the International Astronomical Union, dignitaries from the University of
Manchester and frequent visitors from local bodies; Scouts, Guides, school parties,
etc.
An annexed small lecture
room is home to our computer, giving members internet access as well as the
ability to use astronomical and image processing software. Slides shows and
PowerPoint presentations are held in the Octagon Room. Here the novice and experienced
astrophotographer alike can share pictures with members and not only learn the
craft but is often able to demonstrate new techniques and photographic emulsions
for the benefit of all.
Informal Lectures, including monthly sky notes, are regularly given by the more experienced members, usually prompted by some current interest; nova, eclipse, comet or meteor shower. A cable link to a webcam attached to the telescope in the observatory on the floor above allows members to view the moon and brighter planets, collectively, via the digital projector.
Since 1946, members have had free access to the observatory which is equipped
with an 8" refractor, counterbalanced by a 12" Newtonian reflector. The refractor
is used mostly to view the moon and brighter objects, including the Sun projected
as a 15" disk onto a screen fastened to the tailpiece. Unfortunately, the location
of the observatory, close to the city centre, no longer permits good views of
deep-sky objects - if, indeed, it ever did.
The Godlee double telescopes (made by Grubb of Dublin), which have been in regular use since 1903, are rather unusual although the precedent for this combination had been set 16 years earlier, when Dr Isaac Roberts discussed with Sir Howard Grubb the particular requirements of a large astrographic reflector subsequently erected at Roberts's private observatory at Maghull near Liverpool in April 1885. Here, a 20" Newtonian designed for taking photographs at the prime focus was counterbalanced by a 7" refractor for visual use. On 10 October 1887 Dr Roberts became the first to photograph the spiral structure of the Andromeda nebula using this instrument. The observatory was later moved to Crowborough, Sussex, from where, in 1893, Roberts published his important 'Photographs of Stars, Star Clusters and Nebulae'.

The Godlee telescopes could therefore be regarded as a tried and tested combination in which the City, members of the branch and, indeed, Sir Howard could have every confidence. The ancillary 6" f/6 plate camera mounted on the refractor was an obvious choice for wide field photography, particularly for mapping starfields and for comets. Again there were precedents in the large number of short focal length astrographic lenses of similar aperture in use at the time in America, some of which had been supplied by Sir Howard after trial and error designs had been tested at Greenwich.
If you examine the photograph of the 8" refractor, the 12" Newtonian reflector
can be seen behind.

The prestigious Kopal Lecture is given annually by an astronomer from the University of Manchester' Department of Astronomy or Radio Astronomy in honour of an old friend, the late Emeritus Professor Zdenek Kopal, Manchester's first Professor of Astronomy.
Members meet every Thursday at the Godlee Observatory (except when a public lecture is taking place), when Slide shows, informal talks and occasional 'workshops' as mentioned above take place. Of course the telescopes are also used, weather permitting.
To keep members informed on the activities of the Society 'Current Notes' is published.

Health & Safety Notice |
Safety procedures within the Godlee Observatory are maintained for the safety of members, staff and visitors to the observatory. The minimum age of persons that can enter the Godlee dome area (where the telescopes are situated) and the spiral staircase is 11 years. All visitors must be accompanied by a warden or a trained MAS member when entering the Godlee dome. The walkway on the outside of the dome is no longer accessible, so please do not ask to view or photograph the Manchester skyline. All persons in the Godlee Observatory complex must observe all safety procedures and notices as indicated or advised. All group visits must be pre-arranged to ensure there is an appropriate
number of trained personnel present; this may require a risk assessment
- All visitors will receive safety instruction upon arrival. |
