NGC 253 - an island of stars

NGC 253, the Sculptor Galaxy, is the brightest galaxy in the constellation Sculptor. It is about 11 million light years away from us and is, as I like to say, a southern beauty. In Central Europe it can only be seen very low on the horizon in the fall, on Hakos it moves almost through the zenith.

The data for the image comes from two different observatories, the WAA Southern Observatory and the WAA Remote Observatory, and is therefore the first "pritty picture" with data from the upcoming WAA Remote Observatory which is currently in test mode.

Please note: The following tables are updated every 24 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.
