Luminance and Color channels were scaled and rough color balanced in Astroart. Channels were co-registered in Astroart. The 1 minute IR block exposures were used for the main luminance construction. The 1 minute SkyGlo exposures were used for star size reduction on the larger stars. Level adjustments and curves were applied to bring out dimmer stars. LRGB combine was done in Photoshop. Final touches applied in Photoshop. Final Image size is approximately 1392x1040.
