Bubble Nebula and M52

Revision title: updated processing

My second reprocess of this SHO image in PI, this time adding RGB stars from my D810 from a few years ago.
SHO data taken 25 and 27 Aug 22 at Mt Pinos CA, and RGB data taken July 18 2020 in Death Valley CA.

previous effort: https://www.astrobin.com/cgusi0/B/

Utilitzed Bill Blanshan's SHONormalization v.5 script to help process the SHO image.
Also used the RC Astro BlurX, NoiseX and StarX, along with some curve work and screened the RGB stars back into the SHO image.

Chroma H-alpha 3nm Bandpass 36 mm: 68×300″(5h 40′)
Chroma OIII 3nm Bandpass 36 mm: 60×300″(5h)
Chroma SII 3nm Bandpass 36 mm: 36×300″(3h)
D810 RGB : 29×300″ (2h 25')
Total integration of 16h 5'

The famous Nebula also known as NGC 7635, Sharpless 162, or Caldwell 11,
is an H II region emission nebula in the constellation Cassiopeia.
It lies close to the open cluster Messier 52.

Thanks for looking.

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.
