Revision title: "The Celestial Diver" - Caldwell 33

This was not an easy process. My data besides not being great in general, had some strange background noise of some sort that was difficult to keep at bay. First I thought to just crop the Eastern Veil out and work on that separately. However I do like the whimsical structures of the Pickering Nebula and decided to go for it. I see now that I have oversaturated it while trying to get out a bit more of the filament structures. I will revisit this data a few more times....

The Eastern Veil is part of a large Supernova remnant, the Cygnus Loop with it's neighbors the Pickering's Triangle and the Western Veil Nebula. The entire structure lies at approximately 2400 LY from Earth, has a diameter of approximately 130 LY and a magnitude 7. This object was discovered in 1784 by William Herschel.

Description: I never completely liked the last processing of the Eastern Veil. There was just too much of a stark contrast between sky background an nebulosity and it just didn't look right. And the weather has not gotten better, so the only thing left is to exercise and get better with processing. It is now mid April and I had probably 5 clear nights in total since mid December...

Each time I look at this object, I see a diver in the middle of a back flip before diving into the depths of the Pickering's Sea...

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.
