IC1805 - Heart nebula

The Heart Nebula (IC 1805) is an emission nebula in the constellation Cassiopeia. Its distance is 7500 light years, its size is approx. 100 light years. It was discovered by William Herschel on November 3, 1787.
It mainly contains glowing, ionized hydrogen gas and darker dust lanes. The shape of the nebula is shaped by the stellar wind of the hot stars in its core. It also harbors many young, hot stars, including 24 giant stars with masses greater than 10 solar masses.
The nebula also contains the open cluster Melotte 20.
My longest collection/work so far.
Date of preparation: 16.12.2023-30.01.2024. between for several nights

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.
