Hi Grant
With most digital cameras, the lens cannot be removed to allow you to simply connect the camera body to your scope and take an image through the scope, unless you have an SLR (Single Lens Reflex) camera.
So, you are left with "offering" the lens up to your eyepiece, which can be a bit hit and miss. Scopetronix at
http://www.scopetronix.com/ have a 40mm Maxview eyepiece plus a special adapter that couples your lens to their eyepiece.
I think this is called the "afocal" method. The Scopetronix solution minimises the gap between the front of your camera lens and the eyepiece, which reduces vignetting. I have a Minolta 7Hi and even using the Scopetronix gear, the image looks like you are looking through a tunnel, the central portion is a circle with the photo, surrounded by a dark portion - this is called vignetting.
Hope that helps
Dennis
