Western Veil - C34 (Georg G Albrecht)

Western Veil - C34

Revision title: Western Veil - C34 in HOO

I chose my second mono narrowband image to be the Western Veil. Not necessarily one of my favorites, but it grew on me over the 4 nights I collected the data.
This was collected for a summer project our group on Nebula Photos is working on. I might still try to collect more Ha and SII data in the coming nights if weather permits.

The Western Veil or Witch's Broom, cataloged as Caldwell 34 or NGC 6960, is part of a large supernova remnant in the Cygnus constellation called the Cygnus Loop. The other nebulae are the "Eastern Veil" and Pickering's Triangle. The structure lies at 2400 LY from Earth and stretches over a distance of 3° in the sky, 6 times the size of a full moon. The entire structure is approximate 120 LY in diameter.

Title: Western Veil - C34 (PI process)

Description: After quite some time working now with PixInsight, I decided to revisit my second mono image and do a full PI processing from stacking to the end. There might have been a few lesser subs used as I selected more carefully. But what a difference in outcome. I still can get this better with more practice. Some of my friends and, I am sure lots of you too thinks: Uhhhh, why did he leave the green in it. Well, first I processed it the classical SHO way and killed all the green possible. Then I went to bed and during falling asleep I thought, I actually like that particular green above the main structure...and what the hack, the image is color mapped anyways and there is nothing natural to it! So, for this time I masked everything around and left the green, actually even intensified it a bit in the area I wanted it. It suits the Which well...

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.
