| Notes: | I had a tough time with this cluster ... I started imaging this field on 01/15, and gathered 70 subs in three nights. However, the nearly full moon was only 12-18 degrees away, and was basically shining right down the tube. I found I could not process the glow out without completely washing out the field. I settled for 34 subs taken with the moon out of the field. The large collection of stars to the Southeast (lower left) is M38, the faint swath of nebulosity is LBN 794 |
