Scope: C8 203mm  at f/4.6,  Location: Laguna Mountains, CA  15 September,  2007,   Camera: Artemis285

Exposure: 10 x 8 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. Central gradient removal was performed in Astroart.   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 (or LLRGB) in LAB Color Space. A color adjustment was made to correct the color at low RGB signal levels.   Selective sharpening was applied to nebula features in Photoshop with a layer mask.  Final Image size is approximately 1044x1392
