This video shows you a variety of ways to connect different cameras to your telescope. I attach a DSLR to both a refractor and a Dobsonian, then I connect both a phone and a point & shoot camera to a Dobsonian while showing images of those same connections to a small refractor. Items discussed (in this order) include:
