Double Cluster, NGC 869, NGC 884

Containing 300 to 400 visible stars each, the double cluster (including outer members) is estimated to actually contain over 20K solar masses. The two clusters (NGC 869 and NGC 884) are only separated by a few hundred light-years. The distance to the clusters is about 7600 light-years, and the cluster age is estimated at 13 million years. The field covers ~1 degree.

In this image, it's not entirely clear whether the innermost halos are reflected light from remnant molecular cloud particles, or if the RASA's "feature" of creating halos from brightest stars is affecting the view. Regardless, the view is appealing, and a 16:9 format covering the 1 degree field makes for a nice presentation.

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.
