NGC 6946

#1

Post by kc75star »

Hi

This is NGC 6946 galaxy from light polluted skies in Greece.

https://albireoobservatory.blogspot.com ... -6946.html

NGC 6946 is a spiral galaxy with a pair of branching arms that have a puzzling propensity for supernova explosions. In the 20th century terrestrial astronomers witnessed nine supernovae blazing forth in that galaxy (SN 1917A, SN 1939C, SN 1948B, SN 1968D, SN 1969P, SN 1980K, SN 2002hh, SN 2004et, and SN 2008S). The longest duration between these events was 60 years, suggesting that, as of this writing, another seems about due.



Technical details:

Optics: Vixen VC200L @ f/6.4
Mount: Skywatcher HEQ5 Synscan Pro (belt mod)
Guiding: ST-237 guide chip of SBIG ST2000XM
Camera: SBIG ST2000XM
Filter Wheel: SBIG CFW9
Filters: L
CCD Temperature: 0 degrees Celsius
Constellation: Cygnus
Date: Jul 3, 2021
Location: Korinthos - Greece - Albireo Observatory 1
Exposure:
L=12x600 sec bin 1x1
Calibration: Darks, Flats, Bias

Thanks! You have a fascinating blog. I am impressed with the longevity. You obviously cannot get out often to observe, but you have been reporting for over 15 years.

Really nice shot. Lots of nice grey tones, letting the nature of the galaxy really show through. Thanks for sharing! :)
