June 2013 Challenge (NGC6946) by Tyler Allred:

Here is my entry for the June challenge. It was taken with my homemade 12.5" Zambuto astrograph, dubbed the "Supernova Astrograph". I spent four nights on this target, but one night had terrible seeing... so bad that I decided not to use the data at all. The night I collected the color data wasn't a great night either, but much better. The luminance data was a different story. I finally have the collimation of my scope nearly perfect, and I got two great nights with stable skies, which is unusual here in Utah. We always seem to have the jetstream right over our heads and the seeing is frequently quite bad. At any rate, I combined the decent color data with really good luminance for this image. I have attached a 67% reduced crop, but the full version is worth a look as well.
