I use a bunch of different cameras for astrophotography. The planetary images were made with a 10'-dobsonian (3x Barlow-lens) and with an unmodified webcam (Philips ToUCam). Recently I also use a Quickcam 9000. For deepsky (live) imaging I use the very sensitive Watec 120N (aka Stellacam II) video camera.
The polar caps are clearly visible
Series of images from the an overhead pass of the ISS. Taken with a Philips ToUCam (Webcam) on a 10 inch Dobsonian. Tracking by hand with a viewfinder. In terms of dimensions, looking to the space station at an altitude of about 400 km is similar as watching a small ant at the far end of your living room.
Pass of the Space Shuttle Discovery - STS 124 - 01.06.2008 (at this time several hundred kilometers behind the space station)

The Whirlpool Galaxy M51 (unguided exposure) - compare with the guided exposure (below)
For the construction, which took less than a week I adopted Reiner Vogels VNS (Virtual North Segment) design (Link). This platform (even though not optimized yet) works great for planet tracking but also for deep sky imaging.
Whirlpool Galaxy M51 - Raw image from Watec 120N (max gain, 256 frames, the sky background was in September still relatively bright). The image contains many hot pixels. The equatorial platform, is great for video astronomy. Compare with the unguided exposure of M51 above...
