Scope: Explore Scientific "Levy" Mak-Newt 152 mm at f/4.8,  Laguna Mountains and Dos Picos Park, Ramona, CA   2 and 9 July 2011, Camera: ST8300M

Exposure: 18 x 8 minutes H-Alpha (1x1 bin),  8 x 4 minutes RGB Exposures (2x2 bin) 

Processing: Images were captured with CCDSoft. Aligned/stacked and dark subtracted in Astroart ; Sigma Combine method was used for stacking subs.  All channels were scaled and rough color balanced in Astroart.  Gradient removal  was done in Astroart. Channels were co-registered in Astroart.   The 8 minute 1x1 bin H-Alpha  exposures  were  the main luminance construction. Level adjustments and curves were used to bring out object features.  LRGB combine was done in Photoshop.   A light background noise reduction was applied  to the Luminance channel.    Final touches and color balance in Photoshop. Final Image size is approximately 3272x2454 (cropped and resized to 2400x1800).

All exposures in this image were guided; North is up in this image. The field in this image is from the constellation of Cygnus. The Hydrogen emission structure in this field is a combination of LBN 215 and LBN 234.  The general region is rich with hydrogen emission as evidenced by the red nebulosity. This region in this image is part of a much larger complex known as IC 1318 - commonly known as the "Gamma Cygni Nebula" The Horizontal FOV is 88'.

Image center is located approximately - Equatorial 2000: RA: 20h 20m 00s Dec: +39°07'28"
