Scope: FSQ-106N at f/5, Location: DAA Observatory, Shelter Valley, CA, 18 November and 18 December 2022,  Camera: ASI2600MM (Astronomik type 2c LRGB filters)

Exposure: Exposure:  Panel 1 - Lum 64 x 3.5 min (gain-120 1x1),  RGB 22 x 2 min (gain-101 1x1). Panel 2 - Lum 64 x 3.5 min (gain-120 1x1) ,  RGB - 22 x 2 min (gain-101 1x1)

Processing: Data Collection -  Sequence Generator Pro (as FITs).  Sub-frame calibration - Pixinsight (WBPP). Sub-frame  registration and integration (Average combine - Winsorized Sigma Clipping) - PixInsight (WBPP).  Mure Denoise - PixInsight. Non-linear stretching and gradient removal - PixInsight.  Generation of starless nebulosity Luminance images for later processing - Star XTerminator. Stars only image separately stretched, Luminance starless and mono stars only combine for luminance construction - PixInsight. RGB combine, RGB stretching, Photometric RGB calibration, and Luminance layering - PixInsight. Final finishing  - Affinity Photo. MosaicByCoordinates and GradientMergeMosaic - PixInsight Annotation - PixInsight, Aladin (Simbad), and Affinity Photo. This image is a  LRGB wide band image  with Luminance layering.  Image processed at 6090x7916 resolution. Final Image size is approximately  4308x5600.

North is up in this image.  This image shows the open cluster NGC 1333 / reflection nebula vdB 17 (Ced 16). Also included are vdB 13 and vdB 16. This region is the western part of the large star forming region called the Perseus Molecular Cloud.  Also in this region are dark nebulae Barnard 202 through 206 as well as a few background galaxies. The various components of the Perseus Molecular cloud are about 1,000 light years distant. These objects and some of the brighter stars are identified in the annotated image.  Vertical FOV is approximately 3.22 degrees. Full size image scale is about 2.0 arcsec/pix.

Image center is located approximately - Equatorial 2000: RA: 3h 26m 51s Dec: +30 04' 38"
