NGC 80 Group and Arp 65 (NGC 90/NGC 93)

NGC 80 Group with a beautiful interacting galaxy pair, NGC 90/NGC 93 (Arp 65) in the constellation of Andromeda. The NGC 80 Group also includes galaxies NGC 79, NGC 81, NGC 83, NGC 85, NGC 86, NGC 94, NGC 96, IC 1542 and IC 1546.

This LRGB image was constructed using the data acquired with my mobile setup, the 250mm f/4 Lacerta PhotoNewton and ZWO ASI2600MM Pro camera over a few nights in October, 2024. The luminance data was taken at f/6, while RGB exposures were taken at f/4. To increase image scale, images were x2 drizzle integrated. Images were processed using a combination of traditional image processing techniques (RL deconvolution, multiscale transform) and RC tools (BXT, SXT and NXT).
Exposure detail:
L: 57x300s (Gain 0) and 50x90s (Gain 100) taken @f/6
R: 42x180s (Gain 100) taken @f/4
G: 31x180s (Gain 100) taken @f/4
B: 34x180s (Gain 100) taken @f/4
Total exposure: 10.35 hours

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
