Description

The central region of Abell 407 galaxy cluster about one hour East of Triangulum. My fov isn't quite big enough for all of it.

What caught my interest, and prompted this shot, is the tight group of 9 elipticals in the process of merging into a monster with fire breathing radio jets. The authors of the study linked below proposed naming the group 'Zwicky's Nonet'. They say Fritz Zwicky "noticed" it (not discovered, hmmm) in 1971. The study is excruciatingly detailed but also has some radio frequency pics of the jets.

Study is titled... ‘Zwicky’s Nonet’: a compact merging ensemble of nine galaxies

and 4C 35.06, a peculiar radio galaxy with dancing radio jets
