Scope: Explore Scientific MN152 at f/4.8, Location: DAA Observatory, Shelter Valley, CA, 10 and 13 June 2021  Camera: ASI1600M (Astronomik Gen 2  LRGB Filters)

Exposure: Exposure: L - 71 x 4.5 minutes (gain-170 1x1) ,  RGB - 20 each x 3 minutes  - (gain-139 1x1).

Processing: Data Collection -  Sequence Generator Pro (as FITs).  Sub-frame calibration - Pixinsight. Sub-frame  registration and integration (Average combine -  Winsorized Sigma Clipping) - PixInsight.  Mure Denoise - PixInsight. Non-linear stretching, normalization and gradient removal - PixInsight. Generation of starless nebulosity image (Luminance) - Star XTerrminator.  Curves, Levels, RGB combine, Luminance layering - PixInsight.  Final finishing  - Affinity Photo.  Photometric RGB calibration - PixInsight. Annotation - PixInsight, Aladin (Simbad and NED), and Affinity Photo. This image is a  LRGB with luminance layering. The monochrome starless was combined with a full monochrome image (one stop down in stretch) to minimize star bloat (using pixel math). Image processed at 4656x3520 resolution. Final Image size is approximately  3600x2703.

North is up in this image.  This image captures several Bright Reflection Nebulae - vdB129 (LBD133, Ced 167), and LBN 133. The Dark Nebulae in this image are LDN 768, 769, and 772 as well as a few others from the Dobashi and TGU catalogs. The core structure of vdB 126 can be better seen in the full size image. These objects, information, and some of the brighter stars are identified in the annotated image. Horizontal FOV is approximately 83 arc minutes. Full size image scale is approximately 1.38 arcsec/pix.. 

Image center is approximately - Equatorial 2000: RA: 19h 13m 09s Dec: 22 51' 02"
