Description

This image was captured on various nights in late September, October and November when the moon was not present or not a factor.  The data represents 10h45 with the Baader Moon and Skyglow filtre and 2.5h with the Optolong L-Enhance filtre (to see if I could detect some of the red nebulae).  The dust lanes are definitely more pronounced on the L-Enhance image but I was not able to get much red in the galaxy itself. I blended the two images using GIMP.  Fairly satisfied considering that many of those subs were taken in the glow of the city (Bortle 7).
