It should be possible to do a "parked scan" along the celestial equator ("stripe 82" and "stripe 10") with a Dobsonian telescope, as no tracking is required. I can foresee two issues, though: first, the camera software must support drift scanning; second, it must be possible to make fine adjustments to the orientation of the camera, so the columns are precisely aligned with the celestial equator.

Are these practical with "off-the-shelf" amateur equipment, such as an SBIG camera and a Celestron or Orion Dobsonian? If there is stuff I need to build by hand (a rotator, for example), how much skill and effort should I expect it to require? Are there any other major issues have missed?
