CLICK ON IMAGE FOR FULL SIZE VIEW (4078x2787) Scope: Celestron 9.25 Edge HD 235 mm at f/7, Location: DAA Observatory, Shelter Valley, CA, 24 and 25 March 2023, Camera: ASI294MM (Baader LRGB Filters) Exposure: L -
130 x 3.5 minutes (gain-121 2x2) , RGB - 34 each x 2.5 minutes
- (gain-121 2x2).
Processing: Data
Collection - Sequence Generator Pro (as FITs). Sub-frame calibration
- Pixinsight (WBPP). Sub-frame registration and integration (Average combine -
ESD 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 4078x2787. North is up in this image. This image shows
NGC 3953 along with galaxies MCG +09-20-023 and MCG +09-20-019. NGC 3953 is
a SB(r)bc galaxy at distance of about 57 million light years; MCG
+09-20-019 is a SB (RS)m galaxy at a distance of about 55 million light years.
These predominant galaxies are in a field of background galaxies and
quasars. The many background galaxies are visible in the full
size image. Some of the brighter ones are in the annotated
image and vary in distance from 435 to 1,076 million light years. The furthest objects
visible in this image are the Quasars and their distances (by light
travel time) range from 5.85 to 11.36 billion years (Lookback). These objects,
information, background galaxies, and some of the brighter stars are identified in the
annotated
image. A wider field view of this region
can be seen in an older image here. Horizontal FOV is approximately
39.7 arc minutes. Full size
image scale is approximately 0.58 arcsec/pix. Image Center approximately - Equatorial 2000: RA: 11h 53m 8s Dec: +52°15'25"
