NGC 6712 in Scutum



Scope: C8 f/6.9; Location: Dos Picos Park, Ramona, CA;  11 August 2005; Camera: 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
