Object name: IC0320
This field is on the far southeastern edge of the Abell 426 galaxy cluster. It is better known as the Perseus Galaxy Cluster or the NGC 1275 galaxy cluster. NGC 1275 is about 1.33 degrees northwest of this field. The cluster is about 230 to 240 million light-years distant. I was most interested in IC 320 and PGC 12816. The latter is has a non-redshift distance that fits the cluster. Though its redshift puts it about as much closer to us as IC 320 is further away. Both are listed as cluster members. Their redshift distances may be due to their orbital velocity and being on the outskirts of the cluster which is considered to be very large being over 800 minutes of arc across. I found no non-redshift distance measurements for it. Assuming the redshift distance of 310 million light-years is right for IC 320 I measure its size at 120,000 light-years. PGC 12816 is 95,000 light-years across at its redshift distance. If both are considered to be at the cluster's distance then IC 310 is 90,000 light-years across and PGC 12816 130,000 light-years across. They almost trade places. IC 320 was discovered by Lewis Swift on September 14, 1888. Dreyer says of it "extremely faint, pretty small, round, very faint star close to west". I measure that star at magnitude 14.6. That would be faint in my 10" reflector but easy in the 14" on a good night which this one wasn't.
