Artemis285
Exposure: 12 x 120 sec Luminance exposure (bin 1x1)with Baader IR Block Filter; 8
x 72 sec RGB (bin 2x2)
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. SGBNR was used to smooth background noise on the
final result.
Final Image size is approximately 1392x1040
