Scope: Megrez 80 mm APO at f/5.6,  Dos Picos Park, Ramona, CA   5 August 2011, Camera: ST8300M

Exposure: 13 x 9 minutes H-Alpha (1x1 bin),  8 x 3 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 9 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 3352x2532 (cropped and resized to 2400x1810).

All exposures in this image were guided; North is up and to the left in this image. The field in this image is from the constellation of Cygnus. The Hydrogen emission structure in this field is mostly designated in Lynd's Bright Nebula catalog as LBN310. LBN 310 is a large structure of 360 x  120 arc minutes - well beyond the field of view of this image. However, there are several other Lynd's Bright and Lynd's Dark structure is this view (LDN  905, 908, 910 and LBN 301, 313, 325, 326).  The general region is rich with hydrogen emission as evidenced by the red nebulosity.  The Horizontal FOV is 140'.

Image center is located approximately - Equatorial 2000: RA: 20h 17m 39.3s Dec: +44°39'23"
