I can do 3 minute unguided images with minimal (1-2px) drift and guide indefinitely without imaging with sub pixel corrections. But when it downloads images it makes a massive correction and looses the star (one such correction was 12px in RA. I am wondering if possibly the shutter is sticking a little bit such that the first guide image after image download is blank, the camera initiates a correction then the shutter opens and the next guide image the star is lost.

I experimented with high priority downloads on and off to no avail.
