This Galaxy was believed to be an irregulars galaxy, but in 2005 two spiral arms were discovered. They were missed because of the core’s brightness and their blue color. Star bursts from M82 indicate a hotbed of super nova activity from young massive stars.
The Hubble Space Telescope (2005), revealed 197 massive clusters in it’s star-burst core. The clusters average 200,000 Solar Masses. M82 has an apparent size of 11.2′ x 4.3′ and lies 12.4 Mly away. In 2010 radio astronomers found a strange object that may be a micro quasar.
In perspective M81 lies approximately 130,000 light years away. Making for a nice view of two galaxies in most amateur telescopes. This Galaxy is also known as NGC 3034, 5322, Arp 337, Cigar Galaxy, PGC 28655 and 3C 231.

This pair of Galaxies are a beautiful site in armature telescopes and visible through binoculars. Both galaxies fit within the field of view of binoculars and small telescope. They are gravitationally locked, approximately 12 Million Light Years from Earth.
This was an early attempt to image with new DSLR cameras. This image was taken with a Canon 20D. Canon 20D: 8.2 megapixel APS-C 22.5mm x 15.0mm. Amp glow was an issue with this camera. The ISO 100-1600 extended to 3200-with lots of noise. Series of 7×300 sec. images at ISO 800 & 1600. Darks were taken to minimize noise and amp glow. It was a far cry from current DSLR’s and Mirrorless Cameras.

The Perseus galaxy cluster (Abell 426) is about 250 million light-years from our galaxy and contains more that 500 catalogued galaxies. The brightest member is NGC 1275, at magnitude 11.6. NGC 1275 is a strong source of radio waves and x-rays. Abell 426 is the dominant member of the Perseus-Pisces Supercluster, spanning 15 degrees.. The super cluster extends to 300 million light-years and covers 40 degrees of the winter sky.

Information: NGC 7626 & NGC 7619 & Galaxy Pegasus 1 Galaxy Group
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.
