NGC6946 - The Fireworks Galaxy - Close in and Wide Field

[Laurin Dave]

The weather has been abysmal here for several weeks apart from a brief spell early last Tuesday evening.   The winter targets were too low so I captured some wide field data on the Fireworks Galaxy (2hrs lum on the Esprit100SX46, 50 mins Red 30 mins Green and 20 mins Blue with the GT71ASI1600) to which I have added hi res data of the galaxy I'd taken back in 2018 with my Esprit150ASI1600 and which I have just reprocessed for the umpteenth and possibly final time.  The wide field includes NGC6946  open cluster NGC6939 and part of dark nebula Barnard 150 

From Wiki.. NGC6946 is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus. Its distance from Earth is about 25.2 million light-years.  Discovered by William Herschel on 9 September 1798, the galaxy has a diameter of approximately 40,000 light-years. It is heavily obscured by interstellar matter due to its location close to the galactic plane of the Milky Way, with a dimming of ~1.5 magnitudes.  Due to its prodigious star formation it has been classified as an active starburst galaxy.

 

 

Thanks for looking

Very nice picts!

Very nice widefield that puts different objects into perspective. If only the weather would allow you to collect more data. Getting some colour in the dust would lift this image, I think.

Nice images.....You got part of the B150 dark nebula at the left edge of your wide image. 

The NGC6946 image has great color.

Thanks Wim..  yes indeed, I'll get more time on it next time around to try and get some colour and definition to the dust

Thanks John,   a panel to the left to complete Barnard 150 is in next years plan

Thanks Adam..  its a bit better than my first efforts with the data!
