Hello all,

Taking some flat frames and I noticed some artifacts on the downloaded image. The ADU count is at about 30000 on this stl11000m here. It starts off like the first image then as more images are taken, the artifact retreats to the right side of the frame and then disappears. it does not happen often, but does happen, sometimes during light frames to. does anyone know what this is?

Thanks
Josh
