This rarely imaged galaxy in Hydra about 22Mly distant has several unusual features.

According to ESO, it is bulgeless yet contains a massive black hole. It is an active star former.

It is thought that there are also two smaller black holes in its central region.

The core is quite bright but the outer arms are fairly faint, and really need more exposure than they have received here.

 

The image was shot with an Officina Stellare 300mm f/8 telescope, Moravian G4-9000 camera, Astrodon LRGB filters, DDM85 mount unguided. 3hrs L bx1; 50min each RGB bx2. FOV approx 35' x 30'.
