Astro: Sh2-171
Well part of it anyway. I'd need a heck of a lot of frames to get it
all. Many of the interesting "Pillars of Creation" in this guy are out of frame. Hints of some can be seen on the left. The Luminosity and red frames are a blend of H-alpha and the L or R image using the ordinary LRGB data as the background and blending H-alpha at 50% using the lighten blend mode. This preserved the stars at their L level and their color at the R level making for a much more natural star treatment. There's likely a better way of doing it but so far its the best I've been able to reinvent. I couldn't find much on this guy's distance. One reference says 3000 light years. 14" LX200R @ f/10, L=4x10' Ha=4x30' RGB=2x10' binned 3x3, STL-11000XM, Paramount ME Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

Very nice image Rick. You picked an interesting region in this nebula.
