Based on more than 68 hours of image data captured with a small telescope, this is the spiral galaxy NGC 6946 and the open cluster NGC 6939. Notably, NGC 6946 has seen supernovae discovered 10 times over the past century, with the most recent observation occurring in 2017. Compared to the average occurrence of supernovae in our galaxy, which is about once every 100 years, this frequency is high. For this reason, NGC 6946 is also known by the nickname 'fireworks galaxy.'
