I've wondered what options are available for mounting a fairly heavy digital SLR camera, with a long lens, in such a way that I can track with sidereal motion. Well, at least I think that's how I want it to move. ;-) But seriously, I know of barn door mounts, and I wondered how effective they are, and what their practical limits are. Beyond that, would it make sense to try and locate a used NexStar base, and adapt it to pointing a camera? Just curious, what have been your experiences?
