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.

NGC 1245 Open Cluster in the Constellation Perseus

NGC 1245 is a beautiful open cluster that is found in the constellation Perseus. Visible with binoculars, the majority of the stars in this cluster hover around magnitude 12.

Tech Specs: Meade 12” LX90, Celestron CGEM-DX mount, Canon 6D stock camera, ISO 3200, 27 x 60 seconds using Backyard EOS with darks and bias frames, guided using a Canon 400mm lens with an attached ZWO ASI290MC camera. Image Date: November 24, 2017. Location: The Dark Side Observatory in Weatherly, PA.

Planetary Nebula NGC 1501 in Camelopardalis

NGC 1501 lies in the constellation Camelopardalis (the Giraffe) and is roughly 5,000 light-years away. The internal complexity of this nebula is only hinted at in my image, you can see the various light and dark bands inside. It has also been referred to as the Oyster Nebula, from the bright central star peeking out of the cloudy shell around it. The surrounding cloud was formed when the central star blasted off its outer shells.

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.
