Exposure: 13 x 8 minutes H-Alpha (1x1), 8 x 3 minute 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.  A light background noise reduction was applied to the Luminance construction .  H-Alpha was blended with the red channel 80/20. Final LRGB combine was done in Photoshop  using Luminance Layering.  Color balance  was applied to Red mid range values.  A light sharpening  was applied to the final image.   Final Image size is approximately 1400x1166.
