NGC 6946 - C12 - the Fireworks Galaxy
NGC 6946, also known as the Fireworks Galaxy, is a 9th magnitude face-on spiral galaxy positioned on the border between Cepheus and Cygnus. At 22.5 Million light-years it's one of the nearest galaxies outside of the Local Group. In the past 100 years, 9 supernovae have been observed in NGC 6946, hence the nickname the Fireworks Galaxy. NGC 6946 was discovered by William Herschel on September 9, 1798. It's best seen from northern locations during the months of October, November and December. From latitudes greater than +30N the galaxy is circumpolar. However, from southern locations it appears low down or never even rises at all. Distance 22.5 million light-years, Radius 37,500 Light-Years, number of stars >100 Billion.

NGC-6939 GHOST BUSH CLUSTER
NGC 6939 is[b] [/b]an open cluster in the constellation Cepheus. It was discovered by William Herschel in 1798. The cluster lies 2/3° northwest from the spiral galaxy NGC 6946. The cluster lies approximately 4.000 light years away and it is over a billion years old.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
