Heart Nebula Melotte 15

The heart Nebula lies 7500 light years away in the Perseus arm of our galaxy. The nebula's red color is driven by the radiation emanating Melotte 15, Only 1.5 million years old, contains a few bright stars nearly 50 times the Sun's mass, plus many more containing only a fraction of a solar mass.

I imaged this, one evening from beautiful Bortle 3 skies at 3000 ft elev. I wanted to capture twice the time, but the second night was far too windy and dusty on top of the Mesa.

I then added L-Extreme data from my backyard a couple nights later.

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.
