Our Telescopes

Astrosoc owns five telescopes which range in size, quality and age. These include the Dob, the Grubb, our antique brass telescope and a 4.5" refractor and a 4.5" reflector - more information on these telescopes is available below.

 

All our equipment is kept in the society cupboards in the basement of the Poynting building. Before you use these you must have been shown how to do so by a trained committee member and have read the rules of use.

How to get access to the telescopes

We have a special members' cupboard for members to store their own equipment. If you want to use this cupboard, please complete this form and give it to either the Chairman (Eleanor) or the Secretary (Mark) and they will give you the key to the cupboard. The other cupboards can only be accessed with a committee member present because they contain the nuclear warheads for the revolution!

The Ten Inch

The Ten Inch is our latest and finest acquisition, which former chairman Sam George bought with society funds. It is a brand new SkyWatcher 10'' f/4.8 Newtonian Equatorial. It is big and honkin'! It came with 25mm and 10mm Plossl eyepieces and a good 2X Barlow lens, but we are also looking into getting a 27mm Panoptic for wide field viewing. The focuser is large enough to accomodate 2'' eyepieces but has adaptors for both 2'' and 1.25''. It is mounted on an EQ-6, which weighs around 10kg by itself. It is motorised and allows for easy tracking and scanning. We hope to soon get a cupboard on the roof so we can store it there already set up..

The Grubb

The Grubb is up on the roof of the Poynting Physics Building, in our shed. The mount was made by Grubb in the nineteenth century, the original barrel of which we believe is used by the department for Astrolab. The tubes are later, but are very powerful, giving amazing views of the sky. The Grubb has, until the end of last summer (2003) been covered in pigeon poo! It is now clean and has been used, there still are a few problems but with time these are being fixed.

The Grubb

The two refracting telescopes are located in a run-off shed on the roof of the Physics building. These are 4.5-inch and 5.5-inch in diameter and are mounted parallel to each other on a sturdy equatorial mount.

We have a electronic drive unit which powers an RA motor in order that the telescopes compensate for the Earth's rotation and follow the stars. There is also a DEC motor that can be used for fine up and down movements.

Other Society 'scopes

The Society owns 3 other telescopes excluding the Dob and the Grubb.

These are a 4.5" Refractor that was recently donated to us by Steven Leigh, we are currently working on the mount but expect this to be operational soon.

4.5" refractor

A 4.5" Newtonian reflector which we have only recently acquired.

Last but not least is our antique 3" brass refracting telescope but this is just used for publicity purposes and so is locked away as it is probably quite valuable.

Brass Telescope

The Dob

The Dob is a Dobsonian mount telescope, made for us by Ken Elliot, a member of staff here at the University. It is a 6-inch Newtonian reflecting telescope on a Dobsonian mount. We have two eyepieces for it and it is just about portable enough to be thrown (!) into the back of a car with a large boot and taken to other locations.

Dobsonian Image

The main mirror and tube were donated to the society by an ex-member, Kierra Jarvis, whilst the mount was made by the Physics workshops. We have recently had the mirror re-aluminised. Peter Monks designed the spider and flat assembly and the telescope was first used at the beginning of 1995.

Members 'scopes

As well as the scopes that are owned by the society we often use telescopes belonging to the members of the society, and we have a cupboard to safely store telescopes if anyone would like to bring one along to a meeting.

Currently we have use to Eleanor's (5" Newtonian), Scott's (5" Newtonian) and Samuel's (4" Newtonian) all for use when they are around.
