M83 - The Southern Pinwheel & Surrounding area

Revision title: Re-processed

The southern hemisphere doesn't have many spiral galaxies on offer (at least not many within range of smaller amateur scopes) but this one is a gem, even if not quite as large as the usual northern hemisphere suspects.

M83 was first discovered by Nicholas Louis de Lacaille in 1752, and was the 1st discovered galaxy that lies outside of our local group.
It is about 15 million light years from us, with an apparent size of approx 13 arc minutes.

I was truly impressed at how much resolution the drizzle integration was able to pull from my 100mm refractor.
Equally impressive is the number of faint galaxies in the full field background, and how distant some of those are (check out the annotated revision) ... PGC 713976 for example in the upper right corner is over 1 BILLION light years away! Mindblowing.

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.
