Object name: NGC7619

Designation(s): NGC7619, NGC7615, NGC7617, NGC7621, NGC7623, NGC7626, NGC7631,

Two giant elliptical galaxies are at the heart of the Pegasus I galaxy cluster which is about 160 million light-years distant. NGC 7619 is the brightest member and likely the most massive but otherwise is a rather normal elliptical galaxy. The other major member is NGC 7626. It is a shell galaxy indicating it is the result of a rather recent merger. The shell is easiest to see on the eastern (left) side. Notes at NED indicate it has a dust lane at the core though I was unable to find it in my image. These features, as well as others, cause it to be classified as being peculiar. It also has a LINER core, another indication of the merger that created the shell. Notes also indicate that NGC 7619 likely harbors a lot of dust areas as well. NGC 7619 is about 180,000 light years across its major axis. NGC 7626 is slightly larger, about 195,000 light-years. This larger size is likely due to the merger and only temporary. Both are likely larger than my estimates as determining where the edges are is difficult though NED gives sizes somewhat smaller than I'm seeing. Both were discovered by William Herschel on September 25, 1785. Both are in the second H400 program.

Another rather distorted galaxy in the group is MCG +01-59-058. It is listed as SB? by NED. It seems a rather normal small spiral except for that huge faint arm that pushes the main disk way to the east side of the galaxy making it look "Sloshed". UGC 12510 is listed as E in NED but I see faint arms making it look like a disk galaxy rather than an elliptical. Note the apparent bright linear feature in the lower arm is due to unresolved stars in our galaxy plus a distant background galaxy. They do add to the spiral appearance. It's best to look to the northern side where such background and foreground objects are lacking.

There are 6 other NGC galaxies in the image. I've listed their discoverer and the date below.
NGC 7611, May 26, 1863, Heinrich d'Arrest
NGC 7615, August 16, 1830, John Herschel
NGC 7617, September 23, 1864, Heinrich d'Arrest
NGC 7621, November 25, 1864, Albert Marth
NGC 7623, September 26, 1785, William Herschel This one is in the second H400 program.
NGC 7631, August 30, 1851, Bindon Stoney

In making the annotated image I found nearly all with distance data were members of the cluster so carry a distance of about 160 million light-years. For those, I omitted writing 0.16 over and over. Only those obviously not a member have their distance shown. Some rather bright galaxies had no redshift data. Those are listed with na for not available. They are likely cluster members but I can't say for sure.

Two asteroids are shown in the annotated image as well.
