sh2-86 in Vulpecula (SHO version)

Revision title: HSO version

This is an emission nebula in Vulpecula that doesn't appear to be frequently imaged. The data for this image was accumulated during in total 9 nights between 1/9 and 10/9 2023. This target is weak in OIII, so a total of 15 hours were accumulated with a 6 nm OIII filter. In total the intergration time is just slightly more than 30 hours.

Ha: 23 x 15 min (5.75 hours)
OIII: 60 x 15 min (15 hours)
SII: 39 x 15 min (9.75 hours)

The seeing was particularly good over the entire period.

VERSION HSO:
The color scheme is an HSO mixture in PixInsight:
R = 0.75*Ha+0.25*SII
G = 0.75*OIII+0.25*SII
B = OIII
From this starting point I work mostly with yellow, red and blue color masks for stretching. I like this palette because I think it gives a more natural color.

VERSION SHO:
I felt like reprocessing the image with a more traditional SHO palette.

The stars are "RGB" stars synthesized from the narrowband star images produced by StarXTerminator.

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.
