Bob,
I purchased them on Amazon.com cameras, adapters etc. They run about $18-40. Some have glass in them some don't. Depending on the lens and its internal make-up, there can be some vignetting with some of them, tho not all. And do not overlook the Telescope 32mm to (Your Camera) adapter which enables your camera to be directly coupled to your telescope, If the telescope is capable of using eyepieces.
I use my Old Film Olympus and Old Canon lens the same way
