I own a cheap telescope. What should I look for in a cheap used camera for a first digiscoping experience? I'm looking to spend a very minimal amount of money — hopefully under $100.
Yes there is. If you look at ebay there are for example canon 350d bodies availible from around $40. That is an resonable camera to start out with. A slightly newer model might be a bit better thou as the 350d lacks live view which helps manual focusing.
