Years ago I started digiscoping with my spotting scopes. Basically, you can digiscope by:
1) Holding a camera behind the eyepiece and taking a picture (most common)
2) Using a special mount to hold a camera directly behind the eyepiece without using a camera lens (also referred to us eyepiece projection photography), usually uses a DSLR or removable lens camera.
3) Taking the eyepiece out and using the objective itself as a lens using a special adapter that eliminates the ocular, usually uses a DSLR or removable lens camera.
I always wondered why you couldn't just use riflescope as a lens without using an actual camera lens. Obviously in method #3 you can't remove the eyepiece, so method #2 would be the only way.
Method #1 has the disadvantage of having to go through the cameras lens which accentuates all the optical problems with whatever lens you are using.
So I tried holding up a DSLR camera without a lens to see if I could get an image. I get basically a fuzzy haze and the faint outline of the reticle. When I do this with method to a spotting scope, it's clear and pretty readable. What's up? Why can't I get a decent image? I am holding the camera CCD sensor at the proper eye relief.
