Frames 2 and 3 have small white dots that travel quite the distance across the frame. F#2 look bottom right quad (toward top edge), F#3 look bottom right quad (toward left edge) also another dot appears in bottom left quad (near top right corner). What might these be? By the tutorial I was given the impression that asteroids wouldn't travel quite this distance between frames. But they seem to be too subtle to be artifacts. Any help or insight greatly appreciated.

These are just hot pixels caused (most often) by cosmic rays striking the CCD. You can tell they are just 2-3 pixels big, i.e. quite smaller than all stellar objects.

Ok, Thanks a lot for the clarification. Cheers.
