NGC 520 in LRGB

This is a tiny FOV and a really fascinating galaxy to me! The interactions are visually amazing and looks like a tea spout pouring hot water and steam! The background is incredible with the tiny galaxies of all kinds as well.

NGC 520 is the product of a collision between two disc galaxies that started 300 million years ago, the discs of the parent galaxies have merged together, but the nuclei have not yet coalesced. NGC 520 is one of the brightest galaxy pairs on the sky, and can be observed with a small telescope toward the constellation of Pisces, the Fish, having the appearance of a comet. It is about 100 million light-years away and about 100,000 light-years across. The galaxy pair is included in Arp's catalogue of peculiar galaxies as ARP 157.

Imaged in LRGB on the Planewave CDK 1000 at Observatorio El Sauce, Chile.

Processed by me using Pixinsight and Photoshop.

Processed RGB using SPCC and BXT on stars only with manual preview using FWHM as a guide. Vibrance on starless RGB.
Processed Lum using BXT manual preview. Stretched 2 versions, one for the galaxy and one for the background and blended. Light application of LHE with care to avoid blowout areas.
Final touch ups after LRGBCombination to enhance details and color using Photoshop

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.
