NGC 206 – A Huge Open Cluster in the Andromeda Galaxy

NGC 206 is a huge open cluster found in one of the spiral arms of the Andromeda Galaxy. It is composed of about 300 super bright blue supergiant stars. This object presented a lot of difficulty, at least for me, to resolve the individual stars and took several imaging sessions to get the right composition of images.

From the information I found, this cluster spans over 4000 light years and the stars are probably less than 10 million years old.

Tech Specs: Meade 12” LX90, Celestron CGEM-DX mount, Canon 6D stock camera, 85-minutes combined exposures at ISO 2500 and IISO 3200 using 60 seconds, guided using a Canon 400mm f/5.6 lens with an attached ZWO ASI290MC camera. Image Dates: October and November 2017. Location: The Dark Side Observatory in Weatherly, PA.

ARP 37 (Messier 77) in the Constellation Cetus

Messier 77, also known as ARP 37 (#37 in Arp’s Catalog Of Peculiar Galaxies and NGC 1068 in the New General Catalogue) is a barred spiral galaxy about 47 million light-years away in the constellation Cetus. M77 is the first galaxy in the Arp catalog listed as a low surface brightness galaxy with companions on the arms.

The second image has been over processed in an attempt to bring out additional details in the arms of the galaxy – you can see some of the bright condensation areas around the core.

ARP 229 (NGC 507 + 508) Concentric Ring Class Galaxy

This is another galaxy from the Arp Atlas of Peculiar Galaxies, it contains NGC 507 and NGC 508 and are listed due to NGC 507 having “concentric rings” that I sure can’t make out. They are listed in the Arp Catalog as ARP 229. I’ve included labeled and unlabeled views.

ARP 212 (NGC 7625) Irregular Galaxy in Pegasus

Here is another galaxy from the Arp Atlas of Peculiar Galaxies designated as ARP 212 (also known as NGC 7625). You can just start to make out some of the strange dust lanes in the galaxy in my 59-minute exposure.

Tech Specs: Meade 12” LX90, Celestron CGEM-DX mount, Canon 6D stock camera, ISO 3200, 59 x 60 seconds using Backyard EOS with darks and bias frames, guided using a Canon 100mm lens with an attached ZWO ASI290MC camera. Image Date: October 18, 2017. Location: The Dark Side Observatory in Weatherly, PA.

Edge-On Spiral Galaxy NGC 891 in Andromeda

The edge-on spiral galaxy NGC 891 (in the constellation Andromeda) is what many think our own Milky Way Galaxy would look like if viewed from the edge. This galaxy is about 30 million light-years away in the constellation Andromeda and was discovered by William Herschel on October 6, 1784.
