Processing: Images were captured Artemis Capture (as FITs). Aligned/stacked and dark subtracted in Astroart with Sigma Combine. Luminance and Color channels were scaled and rough color balanced in Astroart. Channels were co-registered in Astroart. The 2 min IR block exposures were used as the main luminance construction with level adjustments and curves to bring out dim stars. Final LRGB combine was done in Photoshop. Final touches were done in Photoshop. Final Image size is approximately 1392x1040.
