Cautiously optimistic about the SV205 for lunar. Tested it today and the image quality seems good. Was only getting 13.5 fps (old laptop with no USB 3) but that should be ok for lunar. Won't really know until I have a clear sky with a Moon to test.
One possible concern is that there are only two selections available for color space, mjpg and YUY2. The former I know is compressed, but I'm not sure if the latter is as well. I don't know a lot about video color spaces and I've found conflicting information about whether YUY2 is a compressed version of YUV or just is a version of YUV that compresses better. If it's compressed, that would be bad, although stacking would (hopefully) mitigate any compression artifacts.
