For anyone who wants to get in to astrophotography, one of the obvious first questions is "How do I connect my camera to the telescope?". Well Celestron has an instructional video on how to. The 10min video covers all types of mounting/connecting methods like A-focal (mostly used with point and shoot cams), prime focus (used with DSLRs), web cam astrophotography, CCD based photography and piggybacking. Of course, it is a promotional video from Celestron, so obviously they promote Celestron products, but it is a good start :)
