IC 1805 - The Heart Nebula

IC 1805, known as the heart nebula is an emission nebula located in the constellation Cassiopeia. Discovered in 1787 by William Herschel, the red glow of this 7500 light year distant target is caused by the radiation emanating from a small cluster of stars near the nebula's center. The cluster is known as Collinder 26 or Melotte 15 contains a small handful of stars the range up to nearly 50 times more massive than our sun.

The Heart Nebula is one of the few nebulae in the night sky that really does resemble its namesake. I had been itching for a month to get back out an image, with weather, the moon, and schedules preventing me from driving out into the high desert of southern California. But I finally managed to get out, and I am so glad I did. The conditions were great, and I was able to capture my longest exposure yet. I don't have the reducer for the 80PHQ, so I had to do a two-panel mosaic. This being my second time processing, I'm much happier with the results here. Thanks to Russel Astrophotography for his great mosaic tutorial. Now that fall is approaching I can barely wait for all the great targets in the night sky.

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.
