There are 4 short color bars in the final image. Each color bar is in red-green-blue format. These color bars can not be eliminated by dark/bias frame calibration or cosmetic correction or integration. I checked the original frames and found there are 4 star-like objects which move slowly between each frames around the place where color bars appear. Then I discussed with some people and they helped to verify that those objects are known asteroids. This is interesting for me because it is the first time that I noticed asteroids are captured in the DSO pictures that I captured.
