Arp270 and Leo Minor Galaxy Cluster in LRGB

Leo Minor Galaxy Cluster in LRGB, March 2023

RGB (3 x 15 x 180s exposures, Bin 2x2 Gain 100)
Total Integration Time = 3.7 hours

This Galaxy Cluster in Leo Minor seemed a very interesting target as it contains a rich field as well as a member of the ARP catalogue of unusual galaxies.
ARP270, or NGC3395/3396, lie on the left hand side of the frame and actually consists of two interacting/merging galaxies, both of which are undergoing intense star forming activity as a result of the tidal interaction.
The largest galaxy in the field of view is the more stable spiral NGC3430. Nearby is the "Hamburger" shaped NGC3424. These and the next smallest CI2608 nearby are called a "cluster" but, but actually range from 26 to 72 million lys apart. By that measure, the Milky Way might be considered part of the same "cluster" when viewed from an different point.
For this image, I actually changed up my processing path, deciding to do more intense noise reduction at the linear stage rather than at the end. I think I like the result.

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.
