Celestron 80mm f/5 refractor

(This 'scope belongs to one of my neighbours, who's kind enough to lend it to me from time to time.)
It has standard (non-ED) optics, so it does produce colour fringes on bright objects, but it's ideal for wide-field imaging, and is effectively a 400mm lens in this mode.
The eyepiece-tube screws off the back to reveal a "T2" thread, so it's easy to mount a camera on the back. There's also a locking-screw on the focus-tube, so that the weight of the camera can't pull it out of adjustment when pointing upwards.

It's a very lightweight and compact package, and produced some good views of Comet Holmes back in November 2007.
