Scope: FSQ-106N at f/5, Location: Tierra Del Sol - SDAA Club Site, CA, 7 June 2018,  Camera: Atik 383L (Astronomik Gen 2 Ha LRGB Filters)

Exposure: Exposure: 8 x 8 min  (1x1 bin) exposure with UV/IR block, 12 x 12 minutes (1x1 bin)  exposure with Hydrogen Alpha filter, 8 x 4 min (2x2 bin) RGB exposures.

Processing: Data Collection -  Sequence Generator Pro (as FITs).  Calibrated, stacked (Kappa Sigma Combine) - Deep Sky Stacker. LRGB channel registration, equalization - Astroart.  Curves, Levels, RGB combine - ImagesPlus. Luminance Layering, final stretch, and finishing  - Photoshop.  RGB calibration - eXcalibrator. This image is a  RGB combine with Luminance layering.  Color saturation in LAB color.  The H-Alpha filter exposure was screen blended into the IR/UV Blocking filter exposure stack and used for the luminance layer. Ha was screen blended into the Red channel -  emission balance of RGB done with Channel Mixer in Photoshop. Images processed at 3352 x 2532 resolution. Final Image size is approximately  2600 x 1950.

North is up in this image.  The large red emission nebula is a portion of the Super Nova Remnant SNR G082.2+5.3. This SNR  contains several other objects from the LBN and DWB catalogs (LBN 313, 325, 326 and DWB 142, 145, 147, 148, 156, 165, 167, 168, 170). There is also a faint Barnard Dark Nebula 345. The SNR structure is estimated to be about 5,000 light years distant. The bright blue star in the upper right is 30 Cygni; the red star is 31 Cygni which has a component star 31 Cygni B. This field is part of the Cygnus-X region in the constellation of Cygnus. These objects  are identified in the annotated image.  Horizontal FOV is approximately 120 arc minutes.

Image center is approximately - Equatorial 2000: RA: 20h 17m 33s Dec: +4609'25"
