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.

IC1396 Elephant’s Trunk nebula

IC 1396 is a mixture of ionized interstellar gas and dust cloud located in the constellation Cepheus, approximately 2’400 light-years from earth. Due to relative proximity of the nebula, it didn’t fit into the field of view of my telescope/camera. My previous picture, which I captured by the same telescope, was created by using focal reducer and therefore nearly fit into the field of view of even smaller CCD chip. However, under dark skies of Milos, there is no need to use narrow band filters and very nice dark nebulae are nicely visible.
