A Little Orion Nebula – NGC 1931

NGC 1931, in Auriga, is a combination of an emission and reflection nebula lying about 7000 light years away.  It is a small, but active star forming area that has been called the miniature Orion Nebula because of the similarity with it, including a smaller version of the Trapezium stars.

Tech Specs: Meade 12” LX90, Celestron CGEM-DX mount, Canon 6D stock camera, Antares Focal Reducer, ISO 3200, 21 x 60 seconds using Backyard EOS with darks, bias and flat frames, guided using an Orion 60mm guide scope with an attached ZWO ASI290MC camera.

Messier 38 Open Cluster in the Constellation Auriga

Messier 38 (M38 or NGC 1912) is a large open cluster found in the constellation Auriga. It lies at a distance of about 4,200 light years away from Earth and is about 13 light years across. Dreyer described it as “Cluster, bright, very large, very rich, irregular figure [shape], large & small [bright and faint] stars”.

Tech Specs: Meade 12” LX90, Celestron CGEM-DX mount, Canon 6D stock camera, Antares Focal Reducer, ISO 3200, 9 x 60 seconds using Backyard EOS with darks and bias frames, guided using an Orion 60mm guide scope with an attached ZWO ASI290MC camera. Image Date: December 14, 2017. Location: The Dark Side Observatory in Weatherly, PA.

Messier 36 Open Cluster in the Constellation Auriga

Messier 36 (M36 or NGC 1960) lies at a distance of about 4,100 light years away from Earth and is about 14 light years across. There are at least sixty members in the cluster. The cluster is very similar to the Pleiades cluster (M45), and if it were the same distance from Earth it would be of similar magnitude.

Tech Specs: Meade 12” LX90, Celestron CGEM-DX mount, Canon 6D stock camera, Antares Focal Reducer, ISO 3200, 13 x 60 seconds using Backyard EOS with darks and bias frames, guided using an Orion 60mm guide scope with an attached ZWO ASI290MC camera. Image Date: December 14, 2017. Location: The Dark Side Observatory in Weatherly, PA.

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.
