"Not Qualified" - 2 points

1) Focus/Sharpness - Yes, appropriate for DSI-II color camera
2) Composition - No - comet too low in frame
3) Star Quality - No - elongation apparent, some unnatural colors
4) Processing Skills - No - Needs flat frame calibration, background colors not normalized, Ring & some stars are clipped
5) Exposure/Depth/Detail - No - Lack of exposure is the main problem with this image.
6) Technical Bonus - Yes - due to the nature of the target
