NGC6871 Open Cluster

NGC6871 is an open cluster located in Cygnus, has less than 50 stars and it is 5135 light-years from Earth. Constellation Cygnus is visually located on the galactic disk of the Milky Way; therefore there are many stars in the background. Particularly interesting are the dark nebulae, surrounding the cluster.

Picture was taken under dark skies of Milos Island and in total, it’s an integration of on 63 minutes.

IC5146 Cocoon Nebula

IC5146, sometimes called Cocoon Nebula, is an emissive nebula located in constellation Cygnus. Central star in the nebula is responsible for the excitation of the surrounding hydrogen gas. On the picture is also captured dark nebula Barnard 168, which creates the strip and it looks like the Cocoon Nebula has a tail.

NGC6946 Fireworks Galaxy, NGC6939 Ghost Bush Cluster

NGC 6946, sometimes called Fireworks Galaxy, is a beautiful spiral galaxy located between constellations Cepheus and Cygnus. It is approximately 22.5 million light-years away from Earth and it’s a part of Virgo Supercluster of galaxies. The name didn’t get from the shape, but due to frequent explosions of supernovae.

Next to the galaxy is located NGC6939 Ghost Bush Cluster, which is a part of our own Galaxy, therefore the distance from earth is “only” 4000 light-years.

The picture is the last one from the day. I slewed to target, switched on auto guiding and went to sleep. Therefore the picture is an integration of 73 photos, each 5 minutes long, i.e. 6 hours of total time. This is probably the picture with the longest integration time from Milos.

NGC7000 North America Nebula

North America nebula, also called NGC 7000, is a giant cloud of ionize hydrogen gas – HII region, located in constellation Cygnus. The shape reminds contour of the North America continent, specifically the eastern cost between Golf of Mexico and Florida. Visually, the nebula is big and it didn’t fit in my telescope/camera field of view. NGC 7000 together with Pelican nebula create a nebulae pair, which is approximately 2000 light-years from Earth.

The picture demonstrates how low light pollution on Milos Island is. The picture is an integration of only 27 pictures, exposure 3 minute each, i.e. 81 minutes in total. It’s impressive – no narrow band filters were used.

NGC 6888 Crescent Nebula

Crescent Nebula, also known as NGC 6888, is a HII region, hot ionized hydrogen gas cloud. The nebula got the shape by high speed stellar wind of Wolf-Rayet star, which is colliding with slow moving mass, ejected by this star during transformation into a red giant. The nebula is approximately 5000 light-years away from us and it can be located in constellation Cygnus.

The picture is the last one from 6.9.2018. In the evening I captured Omega nebula, M80. As a last deep space object I pointed on Crescent Nebula, started auto guiding and went to sleep. Therefore the picture is a stack of 64 pictures; each has 3 minutes of exposure time, thus total integration time 192 minutes.
