13 June 2006; Camera: Artemis285
Exposure: 12 x 180 sec (1x1 bin) Luminance exposures with IR Block Filter, 7 x 90 sec (2x2 bin) RGB
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. Central Gradient was removed in Astroart. Channels were co-registered in
Astroart. Curves and Levels were applied in Photoshop to optimize object
appearance. Final LRGB combine was done in Photoshop using Luminance Layering (or
LLRGB). G2V color correction and final touches were done in Photoshop. SGBNR was used to smooth background noise on the
final result.
Final Image size is approximately 1386x1040.
