NGC7822 - Modified SHO Palette

My first narrowband image! Target is NGC 7822 (Sh2-171) which is located in the constellation of Cepheus towards the North. This nebula contains structures which are similar to the "pillars of creation" from M16, The Eagle Nebula. This target has a weak OIII emission which required longer integration time to capture.

I used a 50/50 combination of a typical SHO and ForaxX SHO palette which results in this beautiful burnt orange and blue colour scheme, with just a hint of some green/turquoise. Although this monochrome data took longer to process compared to my one-shot colour camera, it was actually easier to process due to the extremely clean data, I'm very impressed with this camera and filters. With the QHY268M I used Readout Mode #1, with Gain 56 and Offset 25.

Back focus was in the right ball park, but not 100% correct. Next step is to fine tune this and get stars in the corners looking nice and round!

================

Revision B
I used the same data as the original version but made some minor proessing changes. This version includes the use of BlurXterminator during the deconvolution step, better framing of the target, and a better balance of the colour palette so it's more tri-colour than bi-colour. I much prefer this version as the gold yellow highlights the Sulphur data and adds more depth to the image.

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.
