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.

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.

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.

Open Cluster NGC 6802 Near the Coathanger Asterism

NGC 6802 is a tight little open cluster right next to Brocchi’s Cluster (a.k.a. Coathanger Asterism) in the constellation Vulpecula. I always picked this up on wide-field shots of the region, but this is the first time I put the big scope on this target. Dreyer’s original description of this cluster was Cl, L, vC, E 0deg, st 14…18 which translates to cluster, large, very compressed, extended to zero degrees, stars magnitude range from 14 to 18.
