About this image

The coma has expanded substantial since i imaged 29P five days ago.  There was a window of about 1 hr when high cloud thinned, but the Moon was present.
The first set of images had strange black streaks on the frame as though the pixels had died. One of the USB connections dropped, but i couldn't tell what part was missing.  Drive and data collection continued, any why something effected the frame quality. The second set of images was fine
