The double cluster in Perseus

The "Double cluster of Perseus" is made up of a pair of open clusters: h + χ Persei or ngc884 and ngc869. They are external to the galactic plane and were born from the same giant cloud of gas, but still internal to the Milky Way. They sit in the Arm of Perseus, an outermost spiral branch of our Galaxy and immediately following the Arm of Orion (where our solar system resides). Both are young clusters, aged between 3 and 6 million years, and distant from each other. about 800 light years; the fact that they are so clearly visible even from a great distance (our solar system is about 7000 light-years from them) is an indication of a great real brightness, as well as their size, estimated around 70 light-years in diameter for both objects. Ngc 869 is mag 5.3 and contains about 200 stars, while NGC 884 is mag 6.1 contains about 120. The brightest stars in the Double Cluster are around mag 7.

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.
