ASTRO: NGC 7793 (galaxy in Sculptor)

This is from the best night I had in Namibia. Seeing was very good and the
sky was perfectly transparent till right to the horizon. Stars were
disappearing almost undimmed behind the distant grass instead of 30 degrees
above horizon as they usually do in Berlin.
Actually only the luminance is from that night as I didn’t want to “waste�
such a good night on colour frames.

NGC 7793 is only 12.7 million lightyears away (according to Wikipedia), sort
of M33 a bit further out. I found an article in the web that said that a
microquasar had been found in this galaxy (a quasar that is not driven by
the supermassive black hole in the center of the galaxy). The microquasar
(or it’s jets) is the deeply red object at the upper left border of the
galaxy.
I also like the "horseshoe" of galaxies at the right edge of the picture.

Taken from Kiripotib farm in Namibia, 10" Meade ACF at f/8, Trius SX694
camera, 12x10min L, 4x10min RGB each, image scale 0,62"/pixel.

Interesting on the microquasar. I hadn't realized that any were within amateur range. Shows quite well in your image.

I think your horseshoe of galaxies is the galaxy cluster EDCC 373 which NED says has 21 members but lists no redshift for it or any of the galaxies in the horseshoe. Only the much nearer galaxy above it has redshift data. Though NED says the cluster is over 30 minutes of arc across but the horseshoe is only a minute across. So the identification is iffy.
