Melotte 15 - The Heart of the Heart

Melotte 15 is a open star cluster at the center of IC1805 also known as the Heart nebula. Located in the constellation Cassiopeia, the cluster contains many bright stars that are up to 50 times as massive as the sun. They are blasting the surrounding hydrogen gas with intense radiation which causes the region to glow and emit light.

The Melotte 15 cluster is literally the heart of the Heart nebula, and the main source of the energy required for it to glow in the familiar heart shape. The entire complex is roughly 7,500 light years away from earth. This image is a closeup of the star cluster itself. Little of the surrounding nebula is visible in the frame.

Fortunately, I have had a full week of clear nights that have been perfect for imaging. Unfortunately this means very little sleep. But I'll take a bit of sleep deprivation after the long wet season! I was able to capture 25 hours of data on this target.

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.
