Frank Boyle indicates that he is disappointed with the results of taking pictures through his Celestron C90 spotting scope. I can relate, as years ago, I tried the same with a similar Meade. The problem is that both scopes are reflector telescopes which contain two mirrors that the image goes through, thus degrading image quality. I have friends (George and especially LARRY) who give me fits from the images they get with their refractor (non-mirror) telescopes. All scopes are fixed aperature, which means focusing is critical, and depth of field is not adjustable. We all use 35mm camera bodies. A 35mm negative or slide produces 80+ million pixels versus a digital camera's 3 million pixels. This becomes increasingly important if one wants an 8X10 print, or cropping on a smaller image size, such as a passerine. Our lenses/scopes have cost less than $500, and we get good results from them.
