Perseus Cluster, Abell 426 and NGC 1275 (Perseus A)

Revision title: The heart of the Perseus Cluster

Perseus Galaxy Cluster (Abell 426), is one of the most massive objects in the local universe, containing thousands of galaxies. Abell 426 is particularly bright in X-rays due to a large amounts of hot multi-million degree gas filling the space between its galaxies. In the center of the cluster sits a giant elliptical cD galaxy, NGC 1275 undergoing a merger with a spiral galaxy located in front of it. The core of NGC 1275 is very active with a supermassive black hole residing in the center and powering bright X-ray (Per X-1) and radio (Perseus A) sources. The network of H-alpha emission line emitting gas filaments seen in NGC 1275 is thought to be supported by relativistic outflows and magnetic fields generated by active galactic nucleus. The bluish tendrils seen in front of NGC 1275 are believed to be parts of the spiral galaxy that is being disrupted in the process of merging with NGC 1275.

This LRGB image of the Perseus Cluster and NGC 1275 was created using the data obtained with my mobile setup, the 250mm f/4 Lacerta PhotoNewton and ASI294MM Pro camera riding on the Orion HDX-110 EQ-G mount. The luminance image is a combination of a series of 300s exposures taken at camera gain 0. The RGB color data is comprised of 300s exposures taken at gain 108.

L: 86x300s (Gain 0, bin 1x1)
R: 42x300s (Gain 108, bin 1x1)
G: 36x300s (Gain 108, bin 1x1)
B: 36x300s (Gain 108, bin 1x1)
Total exposure: 16.7 hours

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.
