Cocoon nebula, C19

Revision title: Reprocess with darker background to better show detail

The cocoon nebula is a popular summer target in the northern hemisphere. It's a star forming region and is rich in ha emissions. This is a target I have been working on a while. It always appeared dim in RGB so I experimented with longer subs and integration times to bring out details over four different nights in summer and fall. It has been hard to capture the nebulosity around it and get colors right, and has also been a good target to use to learn how to use some new tools in pixinsight, in particular doing continuum subtraction of red from Ha using pixelmath, creating a synthetic luminance layer, and other new tools.

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.
