I bought him a sony alpha for his birthday earlier this year, and he's been using it with his telescopes and the kit lens. Recently he broke a pair of binoculars and decided to go to home depot for some PVC pipe and stuff and make a lens with the leftover glass. It mounts with the telescope adapter and is manual focus (obviously). Sorry, no pics of it (it looks ridiculous and it's very large), but he's uploaded some (unedited) samples that I just found The image quality is surprising IMO. I really need to put photoshop on his computer, but he's used to film and manages to do well with no PP'ing.
