Scope: FSQ-106N at f/5, Location: DAA Observatory, Shelter Valley, CA,   10 November 2020  Camera: ASI1600M (Astronomik Gen 2  RGB Filters)

Exposure:  32 x 7 min (1x1 bin, gain 124) Luminance exposures, 16 x 4 min (1x1 bin, gain 124) each - RGB exposures.

Processing: Data Collection - Sequence Generator Pro (as FITs). Sub frame calibration - Pixinsight. Sub frame registration and integration (Average combine - Winsorized Sigma Clipping) - PixInsight. Non-linear stretching, normalization and gradient removal - PixInsight.  RGB combine, Luminance layering - PixInsight. Final finishing - Affinity Photo. RGB photometric calibration - PixInsight.  This image is a LRGB combine with Luminance layering. Luminance channel was a blend of Luminance exposures of stars and starless images stretched at different levels. Images processed at 4656 x 3520 resolution. Final Image size is approximately 3600x2700.

North is up in this image. The dominant object in this image is  the reflection nebula LBN 534. This object stretches diagonally across the image. Within this structure are several molecular clouds classified in the Planck Catalogue of Galactic Cold Clumps (PGCC).  Also within this structure is the blue reflection nebula vdB 158. LBN 534 is about 1400 light years distant and calculates to be about 36 light years in its length. Central at the bottom if the image is a small planetary nebula PK 110-12 1 (also cataloged as PN G110.6-12.9). There are also a few background galaxies in this image ranging from 261 to 413 million light years distant. These objects and some of the brighter stars are identified in the annotated image. Horizontal FOV is about 115.  Full size image scale is  about 1.92 arcsec/pix. This image replaces  an earlier image in the Archives here.

Image center is approximately - Equatorial 2000: RA: 23h 56m 16s Dec: +48 55' 21"
