Silver Dollar Galaxy, NGC253 or Caldwell 65 in Sculptor

From Wikipedia:
NGC253 is a spiral galaxy in the Southern constellation Sculptor. It is a starburst galaxy, currently undergoing rapid star formation. It is unusual in that its spiral structure is most evident in it's dust lanes.

NGC253 is between 10.9 and 12.8 million light years distant, depending on measurement method. It is believed to have a super massive black hole at it's centre, slightly larger than that of the Milky Way at about 5 million times the mass of our Sun.

NGC253 is a member of the Cladwell catalogue, designated Caldwell65. The Caldwell catalogue was compiled by Sir Patrick Moore as a list of deep sky objects visible to amateur astronomers. It consists of 109 objects ordered by declination, C109 being the most southerly. The Caldwell catalogue was first published in 1995 in Sky and Telescope magazine.

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.
