Scope: C8 f/6.4; Location: Blair Valley, Anza Borrego, CA;  27 March 2009; Camera: Artemis285

Exposure: 10 x 6 min Luminance exposure (bin 1x1) with IR/UV Block Filter; 7 x 3 min RGB (bin 2x2)

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. All combined stacks were up-sampled to 1392x1040 (1x1 bin resolution). Central Gradient was removed on all channels in Astroart. Channels were co-registered in Astroart. The 6 minute IR block exposures were used for the main luminance construction with level adjustments and curves to bring out object features.   LRGB combine was done in Photoshop. G2V  factors applied to color channels.  Background noise reduction was done with a blurred background layer set on a lighten blend .  Selective sharpening was applied to galaxy features. Final Image size is approximately 1392x1040.
