Description

I had neither heard of nor remembered seeing an image of this galaxy before Mike Feigenbaum uploaded a great image of it recently. It is mag 12.1 but has low surface brightness. This is a 10-hour LRGB+Ha exposure that took me a little over 3 weeks to acquire. I couldn't find much written about NGC-5792 - there is a 2022 paper that has evidence of a low luminosity active galactic nucleus including a nuclear ring of radio emission, and there is a Hubble Space Telescope image of its core (Judy Schmidt from USA - The Core of NGC 5792, CC BY 2.0, wikimedia.org):

My image seems to show an enormous band of young blue stars in the upper right (northwestern) galactic arm, and there is enough detail in the core to see some of the dust shown in the HST image. This galaxy has no common name that I've seen. It sort of looks like a footprint.
