Heart nebula - IC1805

From Skysafari:

IC 1805 is part of a large complex of faint nebulosity is located in Cassiopeia. Derived from its shape, it is nicknamed the Heart Nebula. The very brightest part of the Heart nebula is separately classified as NGC 896, and was the first part of this nebula to be discovered.C 1805 lies some 7500 light years away, in the Perseus arm of the Galaxy. The loose open cluster Melotte 15 lies at the center of IC 1805. The nebula's gorgeous red color is driven by the radiation emanating Melotte 15. Only 1.5 million years old, this cluster contains a few bright stars nearly 50 times the Sun's mass, and many more containing only a fraction of a solar mass.

I managed some decent integration time on this one, relative to my common practices. 🙂 As always this is an unguided series of subs, stacked in APP, and, *no filters* were harmed in the making of this image.

It looks like I caught the fishhead nebula as well. 🙂

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.
