Double Cluster in Perseus

One of my favourite clusters (and one of the first I saw through binoculars during the winter that entered me into the realm of astrophotography).

The acquisition process was really original, it was the first time I lost integration time due to lack of space on the hard drive ... Around 1 h of Luminance. Then 30 min of fits in Luminance could not be opened in Pixinsight, the header was corrupted...

An interesting information from Wikipedia: NGC 884 includes 5 red supergiants. The blue ones predominate: "There are more than 300 blue-white super-giant stars in each of the clusters". Their masses are estimated at 3700 for NGC 869 and 2700 for NGC 884 (I wonder how did they order the NGC objects, by making a 15 object detour to arrive at the cluster that's just by the side of the first...). These clusters are not part of the Messier catalogue.

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.
