Comet C/2007 N3 (LULIN) Animation

Comet Lulin is moving closer to Earth. At closest approach (0.41 AU) on February 24th, the comet may be as bright as 4th magnitude becoming a naked eye object.

We imaged Comet Lulin on 16 January 2009 and on 17 January 2009 to show its motion on the background stars.

Here You can see the animation composed of 2 stacks of 5X120 seconds each, taken remotely from Mayhill (NM) through a 0.10 f/5 reflector + CCD:

In the animation, could I just ask what's the small feature moving around the lower half of this animation?

If I've understood correctly what is the feature you are talking about, it's not a real object but probably a ccd defect.

Thanks for your comment
