A Rose of Galaxies. ARP 273 LRGB

Had a great inspiration to capture this target from an acquaintance and fellow astronomy club member. I thought his take on it was amazing, and obviously others did as well. About a week later he was awarded an IOTD. Congratulations James Peirce. Thank you for the inspiration.

My effort is presented here.

ARP273 is a member of the ARP (Halton Arp) atlas of peculiar galaxies. I have taken great interest in these lately. ARP 273, consisting of galaxies PGC8961 and PGC8970 approx. 300Mly away in Andromeda. These are an interacting pair that show distortions as they pass near and possibly through one another.

Acquisition was made from my backyard observatory (ROR).
11/8/2023 to 11/11/2023

268 X 90sec L 6.7 hours
42 x 240 sec R 2.8 hours
35 x 240 sec G 2.3 hours
38 x 240 sec B 2.5 hours

During processing a on-line friend and someone I look up to offered some data on the same target from their efforts. Thanks Mark Ellis.
I processed the LRGB master lights both separately and combined. In the end I ended up using the data I had acquired and a 50/50 mixture of the stars. Mine and his CDK with diffraction spikes.
I found this combination the most pleasing.

Enjoy,

Chris

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.
