Leo A (aka Leo III) an irregular dwarf galaxy in Leo

Leo A (also known as Leo III or UGC 5364) is an irregular dwarf galaxy, situated approximately 2.6 Mly from Earth. Its size is only about 6 500 light years. Although this galaxy has had fairly recent star formation, I found no evidence of Ha clouds (after 6 hrs of integration time).
There are quite a number of distant fuzzies in this image, up to about 7.4 Gly distant.

Description: Rework of this little gem from last year. Starless processing of widefield galaxy images is always tricky, because any star removal technique will also remove many of the faint fuzzies in the background. Nevertheless, I removed the stars with StarXTerminator (masking the galaxy), and used Pixinsight MMT on the starless image to enhance the weak clouds in the background. I also enhanced the main galaxy somewhat.

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.
