Default 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,

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