NGC 5777 and UGC 9570 are a pair of galaxies in Draco about 100 million light-years away. NGC 5777 is an Sb spiral. It is possible there is a small plume to the S edge of the galaxy but being edge-on it is hard to tell. The companion, UGC 9570 is listed as a dwarf spiral with the same redshift indicating it is probably interacting with ngc 5777. It has a very indistinct structure. There are quite a few very faint quasars in the field as indicated by Simbad but I am unable to identify any in my image. Halton Arp has a thing about quasars not being at redshift distances but being ejected from the cores of active galaxies. Whether he ever showed any interest in ngc 5777 I cannot say but there does appear to be an unusually high number of quasars around this galaxy. My image the result of 45 x 120 second exposures on a hazy summer night a couple of months back.
