Sombrero

Taken during several nights in March 2022 this is the famous so called "Sombrero Galaxy" (#104 from catalogue Messier).
Being found back in 1781, nowadays astronomers consider it one of the most interesting nearby galaxies.
It has a supermassive black hole in its center! Even with small instruments one can see its prominent dark dust lane which hides a lot of galaxy's light behind.

⭐⭐⭐

Calibrated frames in WBBP. Extracted 3 channels to work with each separately.
For every channel used LN with a reference made from best 20 frames which had no noticeable gradients.
Results were much cleaner than those without LN.
Rejection algorithm as always Winsorized Sigma Clipping.
No drizzling.

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.
