NGC 7822, Sh2-170, vdB 2, Berceley 59, NGC7762, King 11

First light of my new Petzval-Apo TSAPO71Q.
It has an improved lens compared to the old Photoline optics

I tried to represent NGC 7822 aka "The Cosmic Question Mark" as realistically as possible.
NGC 7822 is actually a very frequently photographed nebula.
The inconspicuous and faint open star cluster “King 11” (see the annoated revision b) is usually overlooked and is rarely well resolved in the images.
King 11 is a very old open star cluster, which can be seen from the yellowish-pale color of the stars.

The open star cluster “Berkeley 59”, on the other hand, is very young with an age of "only" a few million years.
It contains extremely hot stars that cause NGC 7822's gases to glow.

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.
