NGC 7822: An emission nebula in Cepheus

NGC 7822 is an emission nebula with the embedded star cluster Berkeley 59. The nebula is about 3000 light years away and has one of the hottest stars in this radius to the sun. On the right is the open star cluster NGC 7762.

I was able to expose for two nights in spring 2023 and have now processed the data with Pixinsight:

1) GraxpertAI
2) BXT correction only
3) SPCC
4) NXT with very small amount
5) SXT for the separation of nebulae and stars
6) Increase colour saturation
7) Arcsinstretch and GHS for the nebula and simple stretch for the stars, thereby reducing the size of the stars
8) Curves
9) very light BXT to starless image
10) NXT
11) Merge nebula and stars
12) Fine tuning in Capture One

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.
