Core of Heart Nebula / Melotte 15

Here's the heart of the Heart Nebula, or Melotte 15 and surrounding the nebulostiy. When the light that made this photo left it's source 7,500 years ago, humans were just starting to figure out civilization and copper smelting... you could make the argument we are still figuring out civilization. Some of the large, young stars near the center of Melotte 15 are nearly 50 times the mass of our sun.

This data was my first light with the new Optolong L-Extreme duoband filter and so far I'm a huge fan. Considering half of this data was shot through thin, high level clouds from our suburban back yard and the moon was about 70% the entire time...pretty amazing!

Specs: 45x300" exposures. Calibrated with 30 darks, no flats or dark flats (I was lazy this weekend). TSO 130 Photoline Refractor, Skywatcher EQ6-R mount, ASI294MCPRO camera, Optolong L-Extreme filter. Cooled to 5 degrees F, unity gain. Captured in APT, stacked and Ha / oiii channels extracted with APP, Merged and processed in Photoshop, Final touches in Lightroom.

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.
