M77 #2

So this dataset is actually quite old (for me) -- fall/winter 2020 -- but my first attempts at processing it did not go well.
But after learning about the GeneralizedHyperbolicStretch in PixInsight, the game has changed! I was having a lot of trouble stretching it with the high background, but with GHS, I was able to get quite a nice stretch and still preserve a little of the dim outer arms. I'm quite pleased with how it came out!

M77 is a barred spiral galaxy in the constellation Cetus, and lies 47 million lightyears away. The bar is not obvious in visible light, but is apparent in infrared. It has an active galactic nucleus (AGN), which is a region at the center of a galaxy that is much brighter than it should be over at least some portion of the electromagnetic spectrum. They're thought to be the accretion of material around a supermassive black hole at the galaxy's center emitting a ton of radiation. It's the brightest, as well as one of the closest, galaxies with an AGN, so it is frequently studied.

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.
