Comments Ninteen H-a exposures were taken over a month's time. While blinking to choose the very best, twelve asteroids were found moving through at various angles. All were fast movers between frames, one moved very slowly which was also captured in the RGB frames. Another fast mover passed this same area during one of the Blue frames. Sigma's 'Standard Deviation Masking' combine removed most asteroids except for a couple and the two located opposite and a little lower right inside the nebulea from the 'tornado' sticking out near the top.
