Kim, They are hot pixels. I think they tend to migrate the direction your polar alignment is off in. The reason they are bouncing as they go is I dithered the shots. I didnt do any dark subtraction on the images. Probably should have done that as I have the darks. Cheers, David On 10/29/10 7:46 AM, Kim Hyatt wrote:
David, I'm seeing a couple of faint interlopers in your animation about which I'm wondering. One is just above center to the left and moves up and to the left during the animation. The other, and fainter, is to the lower right and moves in roughly the same direction. Their tracks are not smooth, but jerky and don't appear to be straight lines. Are these artifacts of the imaging/processing or are they something else? Cool animation, BTW.

Here is an interactive animation I put together in flash of some images I shot of Hartley over break.
