Originally posted by DeadJohn I wouldn't expect much from that scope but at the current $109 you might consider it an experiment. Don't trust any telescope marketed primarily by magnification. Any telescope can theoretically reach 300x but you'll get a shaky, fuzzy image, with a lot of chromatic aberration. 100x is a more reasonable maximum practical magnification for a scope of that aperture.
The k-mount isn't a permanent part of that telescope. The k-mount is an adapter ring that goes between the scope and telescope. To learn more about how your camera can connect to a scope google terms like "prime focus telescope" and "eyepiece projection telescope".
Prime focus is done without an eyepiece; the scope become a simple manual lens. For prime focus photo work the advertised scope works like a 600mm long, f12 lens. My guess is it only has 2 elements.
Eyepiece projection couples the camera to an eyepiece. It extends the focal length and as all the extra finicky-ness expected as you increase focal length.
Thanks for the clarification. I asked them to post some photographs
