CLICK ON IMAGE FOR FULL SIZE VIEW (3600x2703) 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"
