Double Cluster in Perseus (NGC 884 & NGC 869)

Captured September 30, 2018

2 hours integration

These gems of Perseus, located right near the border of Cassiopeia, lie about 7,500 light years distant. They can be spotted as a hazy patch with the naked eye with a dark enough sky, or easily through binoculars even from a moderately light polluted suburb. They are believed to be composed of young stars with an approximate age of 12.8 million years, relatively young in stellar terms. The two clusters are moving towards us at 38-39 km/s. Fun fact: if the clusters were the same distance from us as the Pleiades (444 light years), they would fill up a very large portion of the northern sky with many stars similar in brightness to Vega!

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.
