Mount Palomar Observatory– A private facility owned and operated by California Institute of Technology (Caltech). The Facility has a great Visitors Center, and amenities. It is one of the only Working Observatories to offer Guided Tours . If you live in or visit Southern California you must see The 200″ Hale Telescope .
Pegasus Galaxy Cluster 1, rates as one of the most distant objects (faintest) observable with normal amateur Telescopes. This image’s field of view is 52’ 16” x 35’ 5”, It was capture with TEC 5.5” f/7 refractor and SBIG ST10XME at 1.436 arcseconds per pixel. In perspective the full moon is approximately 33’ 57”, about a half of a degree. This Galactic Cluster has an estimated diameter of 6.3 degrees. Currently composed of 13 galaxies (down from original 23) with firm evidence that it hosts an ongoing merger. The map of this image lists some of the galaxies in this image, I have counted 284. Do to its 12.7 magnitude, one needs 10” telescope to observe it visually.
Recent Data from the Gemini + GMOS imaging Globular Clusters fo both NGC 7619 and NGC 7626 support this ( LINK: https://www.gemini.edu/instrumentation/gmos/)
Pegasus Galaxy Cluster 1, is 175.3 (175,341,668.65 ) million lights years away consisting of 8-12 key members. Also known as Pegasus 1 group 50Mpc
NGC 7626 and NGC 7619 (E3) Elliptical Galaxies with a brightness of magnitude 11.2 (2.6×2.3) and 12.2 (2.6 x2.2) respectfully. NGC 7626 is 151,956,256.37 Light years (Ly) away, while NGC 7619 is 179,222,929.54 Ly.
