Caldwell 12 is a spiral galaxy in the constellation Cepheus. It's also known as the Fireworks Galaxy. The galaxy gets its name from the frequent supernova that have been seen there. It's located on the border of the constellations Cepheus and Cygnus.

Caldwell 12 was discovered by astronomer William Herschel in September of 1798. It's about 22 million light years away and about 40,000 light years across.

Caldwell 12 is best viewed during the fall. It's catalogued as Caldwell 12 in the Caldwell catalogue of 109 deep sky objects that can be observed with amateur telescopes.

This picture was taken wih a GSO RC8 telescope at a Focal length of 1625mm. It is made up of an integration of 230 5 minute images. A touch over 19 hours of exposure.

The fireworks galaxy is not a very bright object and is fronted by numerous stars from our own galaxy. The galaxy is far beyond the starfield in the image.

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.
