IC1805 The Heart Nebula

Following extended cloudy nights, I managed to gather some data to present a decent narrowband image of the Heart Nebula. Lots of data from nights with either a full moon or below average seeing, but I can't be picky these days. And that is a shame as this is a beautiful emission nebula 7500 light years away, located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel in 1787. It displays glowing ionized hydrogen gas and darker dust lanes.

I minimized the stars to have the nebula pop out more, but I am not sure if I really like this look (original version). So, I added another version with a more pronounced starfield.

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.
