CLICK ON IMAGE FOR FULL SIZE VIEW (2600x1950) Scope: FSQ-106N at f/5, Location: DAA Observatory, Shelter Valley, CA, 10 September 2018, Camera: Atik 383L (Astronomik Gen 2 Ha LRGB Filters) Exposure:
Exposure: 16 x 15min (1x1 bin) exposure with UV/IR block filter, 8 x 4.5 min (2x2 bin) RGB
exposures.
Processing: Data
Collection - Sequence Generator Pro (as FITs). Exposure calibration,
LRGB registration, and stacking (Median combine - Winsorized Sigma
Clipping) - PixInsight. LRGB channel registration,
equalization and gradient removal - PixInsight. Curves, Levels, RGB
combine, Luminance layering - PixInsight. Final finishing -
Photoshop. RGB calibration - eXcalibrator. This image is a RGB combine
with Luminance layering. Images processed at 3352 x 2532 resolution. Final Image size is approximately
2600 x 1950. North is up in this image. The
main feature of this image field is the series of molecular clouds from lower
left to upper right. These clouds are cataloged in the Planck Catalog of
Galactic Cold Clumps (PGCC), but they are not in any of the well known
Astronomical catalogs. Also in the field is a significant number of background
galaxies - some of them are visible through the molecular clouds. One of these
galaxies is from the NGC catalog (NGC 7223). Many of these background
galaxies are members of galaxy groups. The two galaxy groups in this field are
[CHM2007] HDC 1179 (total of 10 members) and [CHM2007] LDC 1503 (total of 18
members, some out of the field of this image). These objects and some
of the brighter stars are identified in the annotated
image. Horizontal FOV is approximately 120 arc minutes. Full size
image scale is 2.77 arcsec/pix. Image center is approximately - Equatorial 2000: RA: 22h 09m 51s Dec: +41°33'30"
