a small dobsonian would work i have a 12 inch skywatcher

A "Reflex Lens" or "Mirror Lens" is a miniature Schmidt-Cassegrain telescope used as a telephoto lens. They were popular back in the 80's as a poor man's extreme telephoto lens. You can buy some used in good condition quite affordably. The Tamron 55B or 55BB was built on the Tamron Adaptal mount--the same lens could be used with any lens mount for which an apropriate adapter was available. I used a Tamron 55BB on a micro four-thirds camera (Olympus E-M5) to take this picture:

This "lens" is easy to use on your camera, and I think with a little cleverness you could figure out how to put an objective lens in front of it to look through it by eye as well.

Thank you!! For your suggestions folks!

Oh, I should have said when I was recommending mirror lenses, that there are a lot of modern ones that are crap. The Tamron ones are good, the Zeiss ones are better (of course), and some actually made by the major camera/lens makers are good. Minolta (now Sony) made the only one that is capable of autofocus. There is a whole group here on Flickr dedicated to them, where they could tell you which ones are good and bad:

Of the ones made recently that you will find all over Amazon and eBay, I hear that Opteka is low quality. One thing to watch out for is that Vivitar used to be a serious maker of photography equipment, but the name was sold.
