Processing: Images were captured with CCDSoft. Aligned/stacked and dark subtracted in Astroart ; Sigma Combine method was used for stacking subs.  All channels were scaled and rough color balanced in Astroart.  Central Gradient removal  was done in Astroart. Channels were co-registered in Astroart.   The 10 minute 1x1 bin  and 5 minute 2x2 bin H-Alpha  exposures  were  used  for the main luminance construction. Level adjustments and curves were used to bring out object features.  Ha and red exposures were blended for the Red channel.  LRGB combine was done in Photoshop.    A light background noise reduction  was applied  to the LRGB image.   Final touches and color balance in Photoshop. Final Image size is approximately 3352x2532 (cropped and resized to 2000x1500).
