On the software part, I use Tangra for measuring video imagery and AstroRecord
for measuring DSLR photographs.

For sidereally tracked telescopic CCD imagery I use Astrometrica.

These are all capable of getting arcsecond accuracies (depending on the optics
used of course. But even with a DSLR and 35 mm lens I get astrometric accuracies
of no more than 7" - the largest limiting error factor is the timing, not the
astrometric accuracy. With video and a 50mm lens the accuracy typically is
around 7" to 15", on single frame measurements).

Maybe also ad that a good time source is absolutely necessary. For photography I
use a DCF77 radio-controlled clock. For video a GPS time inserter.
