The Grus Quartet.
This gravitationally bound spiral group of galaxies, NGC 7582, NGC 7590, NGC 7599, and NGC 7552, makes up the Grus Quartet which is located in the constellation Grus. The centre galaxy NGC 7582 contains a supermassive black hole with a mass approximately 10 million times that of our Sun. The distance to this galaxy group is estimated to be between 60 and 70 million light-years. This is just over an hour of data captured from my backyard. 127×30″ unguided from suburbia.
