Heart Nebula IC1805

Finally managed to capture some images of this beautiful object. I would still like to capture more data and perhaps add to the existing files.

I am also not sure if I like the colors this turned out to be and who knows, maybe some day I will re-process this and change the color scheme. So many options...

Interesting information on this nebula:

The brightest part of the nebula (a knot at its western edge) is separately classified as NGC 896, because it was the first part of the nebula to be discovered.
The nebula's intense red output and its morphology are driven by the radiation emanating from a small group of stars near the nebula's center.
This open cluster of stars, known as Colliander 26 or Melotte 15, contains a few bright stars nearly 50 times the mass of the Sun, and many more dim stars that are
only a fraction of the Sun's mass.

The Heart Nebula is also made up of ionized oxygen and sulfur gasses, responsible for the rich blue and orange colors seen in narrowband images.
The shape of the nebula is driven by stellar winds from the hot stars in its core. The nebula also spans almost 2 degrees in the sky, covering an area four times
that of the diameter of the full moon.

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.
