Here is an intriguing beast, the chaotic galaxy NGC 7793. NGC 7793 joined the hit parade in 2014 when a Hubble image uncovered the galaxy’s secret. According to NASA, “NGC 7793 is actually a very dramatic and violent place. Astronomers have discovered a powerful micro-quasar within NGC 7793 — a system containing a black hole actively feeding on material from a companion star. A micro-quasar is an object that has some of the properties of quasars in miniature. While many full-sized quasars are known at the cores of other galaxies, it is unusual to find a quasar in a galaxy’s disk rather than at its center.”

I used a 27 inch Planewave located at iTelescope in Siding Springs, Australia. 1.2 hours of imaging time, divided equally among R, G and B, binned 1X1. Subs aligned and stacked in PixInsight, everything else in StarTools, except for some minor twiddling in Affinity Photo.
