I tested a new guidescope concept for the first time last night, and images The Mice while I was at it. This is a combine of 11 images - nine 5-minute images and 2 15-minute images.
You can see some structure in both galaxies as well as lots of the "tails." There is some visible structure in the tail that extends upward (north), and a hint of what remains of the spiral structure of the lower galaxy. Numerous background galaxies are also visible.
Taken with the Newastro Remote Telescope - a C14 and ST-10XE on a Paramount ME at New Mexico Skies.
The guidescope? A 50mm finder from a C14, with an ST-237 in it. Focal length of the guidescope was a mere 175mm. It's not really quite long enough (several individual images were trailed), but it did surprisingly well. As a guidescope, it's probably fine for scopes up to about 2500mm in focal length with the STV or ST-237. Mike Rice made a custom collar for attaching the camera to the finder. One nice thing about the finder as a guidescope: it focuses by turning the front element in and out, so camera angle is not affected by focusing.
