  In the bottom right hand corner there are 2 lots of dots 1 and 2 are moving top to bottom . 3 and 4 are moving right to left and to me that does not make sense , I thought that the asteroids were in a slight curved path not moving through right angles . Ian

  I think that those dots are just hot pixels caused (most often) by cosmic rays striking the CCD.

  All are just hot pixels. You can tell them apart from stellar (like) objects by that they are just 1-2 pixels big, and don't have dimmer edges than the center (not to mention they appear only on a single image out of the sequence)
