Description

NGC 6946 The "Fireworks Galaxy" in Cepheus, up to now I did not now it exist. It is a beautiful spiral that is prone to photographed from the northern hemisphere with medium sized telescopes. There are some very colorful stars around this galaxy, in fact I did not apply any color saturation function.

In the summertime we have only less than 2 hours of night sky suitable for AP, hence the low total exposure time.
As clouds came in and the moon started to affect the image I came to the conclusion that 38x240s must be enough.

However for the first time in a long while we gathered with other AP crazies for a session and introduced an old schooler to his new ASIAIR. We had a blast and we need more of that again!

Hope you like it.

Wikipedia:NGC 6946, sometimes referred to as the Fireworks Galaxy, is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northernconstellations of Cepheus and Cygnus. Its distance from Earth is about 25.2 million light-years or 7.72 megaparsecs,[2] similar to the distance of M101 (NGC 5457) in the constellationUrsa Major.[3] Both were once considered to be part of the Local Group,[4] but are now known to be among the dozen bright spiral galaxies near the Milky Way but beyond the confines of the Local Group.[5] NGC 6946 lies within the Virgo Supercluster.[6]Discovered by William Herschel on 9 September 1798, this well-studied galaxy has a diameter of approximately 40,000 light-years[dubious – discuss] , about one-third of the Milky Way's size,[7] and it contains roughly half the number of stars as the Milky Way. It is heavily obscured by interstellar matter due to its location close to the galactic plane of the Milky Way.[8] Due to its prodigious star formation it has been classified as an active starburst galaxy.[5]Various unusual celestial objects have been observed within NGC 6946. This includes the so-called 'Red Ellipse' along one of the northern arms that looks like a super-bubble or very large supernova remnant, and which may have been formed by an open cluster containing massive stars. There are also two regions of unusual dark lanes of nebulosity, while within the spiral arms several regions appear devoid of stars and gaseous hydrogen, some spanning up to two kiloparsecs across.[5] A third peculiar object, discovered in 1967, is now known as "Hodge's Complex".[9] This was once thought to be a young supergiant cluster, but in 2017 it was conjectured to be an interacting dwarf galaxy superimposed on NGC 6946
