It turns out that there is a catalog of peculiar galaxies! This is my type of catalog!
The Atlas of Peculiar Galaxies is a catalog of peculiar galaxies. It was produced by Halton Arp in 1966 and was originally published by the California Institute of Technology in the same year.
The primary purpose of the catalog was to present photographs of examples of the different kinds of peculiar structures found among galaxies.
There are a total of 338 galaxies presented in the atlas.
This is one of them. I captured it last night shortly after moonset.

The Arp 28, magnified, is below.
This galaxy was fun to find and tease out details because it is so small and dim,

So, what is peculiar about Arp 28? It is in the class of “Spiral Galaxy with One Heavy Arm.”
I can see that.
Arp 28 was one of the observing challenges for October 2019 in the EAA forum on Cloudy Nights. These challenges are alway fun and rewarding.
