Scope: C8 203mm  at f/4.8,  Location: Blair Valley, Anza Borrego Desert, CA  3 November,  2007,   Camera: Artemis285

Exposure: 8 x 7 min H-Alpha (1x1), 8 x 1.5 min RGB Exposures (2x2). 

Processing: Images were captured  with Artemis Capture (as FITs).  Aligned/stacked and dark subtracted in Astroart with Sigma Combine.   H-Alpha  and Color channels were scaled and  color balanced in Astroart.  Channels were co-registered in Astroart.  Luminance construction consisted of the H-Alpha exposure.  Curves and Levels applied in Photoshop to the Luminance construction to optimize object features.  Final LRGB combine was done in Photoshop using Luminance Layering in LAB color Space. A color adjustment made to correct the color at low RGB signal levels.  A light background noise reduction was applied in PixInsight LE (SBNR)  Selective sharpening was applied to nebula features in Photoshop with a layer mask.  Final Image size is approximately 1040x1392
