Exposure: 15 x 240 sec  Luminance with IR Block Filter (bin 1x1); 8 x 120 sec RGB (2x2 bin)

Processing: Images were captured Artemis Capture (as FITs). Aligned/stacked in Registax 4 and saved as FITS. Luminance and Color channels were scaled and rough color balanced in Astroart. Central Gradient removal was performed in Astroart. Channels were co-registered in Astroart. The 240 sec IR block exposures were used as the main luminance construction with level adjustments and curves to bring out dim stars. Final LRGB combine was done in Photoshop.   Final touches were done in Photoshop.  PixInsight LE SGBNR was used for background noise reduction. Final Image size is approximately 1392x1044.
