M58 Barred Spiral Galaxy

It's probably kind of nuts but I keep trying to stretch the limits of how far and how faint of a deep sky object I can image. This latest attempt is a barred spiral galaxy called M58. These kinds of galaxies are somewhat rare and there are only 3 other barred spirals in the Messier catalog. The poor thing doesn't have a fancy name, so maybe you can suggest one. M58 is located 68 million light-years from Earth and is a very dim magnitude 10.5. I like how you can clearly see the bar structure at the center of the galaxy. It also has a supermassive black hole at its center with a mass of about 70 million solar masses. I could see great clouds of pine pollen flying through the air when my headlamp was turned on, so that may have detracted from this image. It's always something!

This image is from a stack of twenty-four 300-second exposures at 2310mm focal length, calibrated with 20 each dark, flat, and dark flat frames, then post-processed with StarNet++ and 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.
