NGC 2336 / IC 467 Galaxy Pair



Scope: Celestron 9.25 Edge HD 235 mm at f/7, Location: DAA Observatory, Shelter Valley, CA, 18 Dec 2022,  Camera: ASI294MM (Baader  LRGB Filters)

Exposure: L - 72 x 3.5 minutes (gain-150 2x2) ,  RGB - 22 each x 2 minutes  - (gain-121 2x2).

Processing: Data Collection -  Sequence Generator Pro (as FITs).  Sub-frame calibration - Pixinsight (WBPP). Sub-frame  registration and integration (Average combine -  Winsorized  Clipping Rejection) - PixInsight (WBPP).  Mure Denoise - PixInsight.  Non-linear stretching, normalization and gradient removal - PixInsight.   Curves, Levels, RGB combine, Luminance layering - PixInsight. Generation of starless Luminance image for later processing - StarXTerminator. Photometric RGB calibration (SPCC) - PixInsight.  De-convolution - BlurXTerminator.  Final finishing  - Affinity Photo.  Annotation - PixInsight, Aladin (Simbad and NED), and Affinity Photo. This image is a  LRGB with luminance layering.  Image processed at 4144x2822 resolution. Final Image size is approximately  3200x2203.

North is to the Left in this image.  This image shows NGC 2336 - classed SAB(rs)bc and at a distance of about 102 million light years. Along with  NGC 2336 is a paired galaxy IC 467 - classed SAB(S)c? and at a distance of about 104 million light years. This pair are separated by about 0.6 million light years (angular separation of about 20.3 arc minutes). The field has multiple background galaxies that can be seen in the full size image. Some have redshift estimated distances  - PGC2781510 is 1,960 million light years; PGC2782391 is 1,176 million light years. The furthest objects visible in this image are the Quasars  and their distances  (by light travel time) range from 3.419 to 10.56 billion years (Lookback).  These objects, information, background galaxies, and some of the brighter stars are identified in the annotated image Horizontal FOV is approximately 38.4 arc minutes. Full size image scale is approximately 0.72 arcsec/pix.

Image Center approximately - Equatorial 2000: RA: 7h 29m 9s Dec: +8004'04"
