 After watching the animation , the still frame's Comets almost appear to move very slowly.

I noticed several small satellites in the animation traveling from the middle left side going approx. 45 degrees right toward the top.  Found at least 30 satellites and I know there must be more.  Tesla anyone?  Please respond if you see them. A few of them are pairs.  If you want to be crazy like me use a magnifying glass on the screen to view them. <grin>

(jeanc)  Hot pixels do not move acrossed the screen.  The images I see are moving in the same direction at the same speed.  Check the actual animation and you will see what I mean.

They do move if the telescope wasnt precisely tracking the stars - in fact the motion of the pixels appears to be roughly the same as 260P.

 

They're clearly hot pixels, they have a much narrower PSF than the stars.

 

Anyway, I got 6.5 hours of data of these two on Saturday night, and will try to make my own movie!
