IC 1805 HOO RGB stars

Revision title: Melotte 15, candles of the heart

Two different telescopes were used for RGB stars and HOO. For the RGB stars I used the 150 mm. In order to blend the stars I used the pixelmath expression In PixInsight: combine(ImageHOO,ImageRGB,op_screen()). Then I worked on curves in PI and Adobe Lightroom Classic CC.
In this picture we can contemplate the central region of IC 1805 comprising the open cluster Melotte 15 formed by young stars of 1,5 million years of age. The dust and gas are ionized and light is reflected in multiple ways giving profound shadows and subtle illumination on this turbulent and romantic cosmic scene.

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.
