Processing: Images were captured Artemis Capture (as FITs). Aligned/stacked in Registax
3 and saved as FITS. Luminance and Color channels were scaled and rough color balanced in
Astroart. Channels were co-registered in Astroart. The 120 sec exposures were used as
the main luminance with level adjustments and curves to bring out object detail
and preserve core detail. Final LRGB combine was done in Photoshop using Luminance Layering (or
LLRGB). Color
balancing and final touches were done in Photoshop. Background noise was
subtracted (using dust and scratches difference layer with high threshold -
stars and object mask). SGBNR was used to smooth remaining background noise on the
Luminance Channel.
Final Image size is approximately 1392x1040 Image Center is approximately - Equatorial 2000: RA: 21h 40m 22s Dec: -23°10'43"
