CLICK ON IMAGE FOR FULL SIZE VIEW (2800x2100) Scope: FSQ-106N at f/5, Location: DAA Observatory, Shelter Valley, CA, 11 November 2018, Camera: Atik 383L (Astronomik Gen 2 LRGB Filters) Exposure:
Exposure: 16 x 12min (1x1 bin) exposure with UV/IR block filter, 8 x
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 3354 x 2529 resolution. Final Image size is approximately
2800 x 2100. North is up in this image. The
large cloudy nebulosity in this image field is part bright nebula and part
various dark nebula. This field is part of the larger LBN 786 (AKA IC 360); it
is the southwest quarter of the LBN 786 region. The most prominent dark nebula is
a series of Dobashi dark nebulae that also includes Barnard 208 (darkest region
toward the upper left). The field also contains LDN 1498 and 1499 as well
as other dark structures noted in the TGU, Dobashi, and PGCC (Planck Catalog of
Galactic Cold Clumps) catalogs. There are several background galaxies - the most notable
is NGC 1508 with a redshift distance estimate of 326 million light years.
Others (UGC 02988, PGC 014451, 014493, LEDA 3089489) are annotated and have
distance estimates from 180 to 326 million light years.
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 2.57 arcsec/pix. Image center is approximately - Equatorial 2000: RA: 04h 10m 02s Dec: +24°53'02"
