NGC 6914 Region in Cygnus



Scope: Megrez II  f/4.3 Location: Dos Picos Park, Ramona, CA   11 August 2005  Camera: Artemis285

Exposure: 8 x 300 sec H-Alpha, 10 x 90 sec IR Block, 8 x 60 sec RGB Exposures

Processing: Images were captured Artemis Capture (as FITs). Aligned/stacked in Registax 3 and saved as FITS. Luminance, H-Alpha,  and Color channels were scaled and rough color balanced in Astroart. Channels were co-registered in Astroart.  The H-Alpha exposure was the main exposure for the luminance construction - the IR block exposure was combined with the H-Alpha for star depth with the fainter stars.   Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB).  Heavy dust and scratches HA channel (exposing nebula and eliminating stars) was partially subtracted from the green and blue channels to balance the red in the nebula. 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 1382x1034.

All exposures in this image were guided; North is to the Left in this image.  This is region around a reflection nebula called NGC6914. This nebula is the small blue green nebulosity in the left central part of the image. The rest of the field in this image contains nebulosity consisting of  hydrogen in the characteristic primary emission band.  The Horizontal FOV is 90'.

Image center is located approximately - Equatorial 2000: RA: 20h 25m 15.224s Dec: +4210'46.156"
