Description

I captured this back in 2021 with my 16" dob, but just processed the data recently. I did a deep dive on some of the objects in the image to see which were associated with each other. As it turns out, NGC 5613 is about 210 million light years beyond NGC 5615 (Arp 178) and so they aren't associated with one another. On the other hand, little NGC5615 seems to indeed be a small satellite galaxy of NGC 5615 as it is at about the same distance. NGC 5613 appears to be about the same distance (390 million light years) as the edge on galaxy in the lower right, UGC9224 (PGC 51426).

I tried to focus on bringing out the inner dust ring and intertwined ring of star forming regions around the AGN core of NGC5614. There wasn't enough data to show the outer dust ring that shows up in some other images. Maybe I'll try to get a deeper image sometime!

Interestingly, there seems to be only one galaxy in the image (NGC 5609) between 390 and around 2 billion light years where there seem to be numerous galaxy clusters. Its as if there is a 1.5 billion light year void behind the brighter foreground galaxies. See rev B for more details on the objects in the image. I have color coded them to indicate distance, with redder being farther away.

The most distant named galaxy with a good redshift measurement that I could find is SDSS J142459.29+345510.9, which is a remarkably bright AGN (active galactic nucleus) galaxy despite being around 4 billion light years away. The more distant objects are all quasars, while the nearest object labeled is a white dwarf.
