Hearth Nebula's Core SHO-RGB

Revision title: v2

September 2023 Sii data and RGB stars are added here to Ha-Oiii recordings taken on October 2022.
As shown in the picture below, the Sii signal returns a completely different image than the Ha, that gives increased color saturation and dynamic to the SHO composition.
The stars RGB data was taken in 2022, yet never used before.

A wide field of the nebula, taken with a shorter focal, is visible here.

The Heart Nebula (Running Dog Nebula, IC 1805, Sh2-190) is an emission nebula, 7500 light years away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. The nebula morphology and emission is shaped by the radiation emanating from a small open cluster of stars, known as Collinder 26 or Melotte 15, that 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 “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.
