CLICK ON IMAGE FOR FULL SIZE VIEW (2600x1950) 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 obscuring the Super Nova Remnant SNR G082.2+5.3
(the SNR structure would be better observed in OIII).
This SNR structure is difficult to see in this image due to several other objects from the LBN and DWB catalogs
that dominate - (LBN
313, 325, 326 and DWB 142, 145, 147, 148, 156, 165, 167, 168, 170). Some of
these Ha emissions may be related to but behind the SNR shock wave. Perhaps only
1/6th of the SNR arc is encompassed by this field. 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: +46°09'25"
