NGC 6946, The Fireworks Galaxy

A spectacular Fireworks Galaxy, NGC 6946 located on the border of the constellations of Cepheus and Cygnus. NGC 6946 has a high rate of star formation and is a host to numerous supernovae. Because of the frequent supernova outbursts observed in NGC 6946 (with 10 supernovae detected over the last 100 years), it is often referred to as the "Fireworks Galaxy".

The galaxy was imaged over a few nights in July and August of 2021, right before the beginning and after the end of the Southwest monsoon season. This image is a combination of the LRGB and H-alpha exposures taken with the 250mm f/4 Lacerta Photonewton and ZWO ASI294MM Pro imaging camera:

L: 48x300s (Gain 0, bin 1x1)
R: 40x180s (Gain 108, bin 1x1)
G: 28x180s (Gain 108, bin 1x1)
B: 32x180s (Gain 108, bin 1x1)
Ha: 21x600s (Gain 200, bin 1x1)
Total exposure: 12.5 hours

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.
