SH2-122 - Rarely imaged, faint molecular cloud and background galaxies in Pegasus(LRGB)

This is such a fascinating and rare target, thank you to Mike for imaging it so well and providing the data! The numerous galaxies are amazing too!!

SH2 122 is a faint molecular cloud in Pegasus. It is thought to be lit by an embedded star that is not visible and may be associated with the molecular cloud MBM 55 around 500 light years from here. The field hosts a great many background galaxies which are incredible to see when zooming in!

Left of the frame is Markab a magnitude 2.48 Giant blue star that may be a variable blue star, I liked the effect it had on the image and retained the color and reduced the intensity. Markab is the third brightest star in Pegasus it lies 133 light years from here, it is one of the 100 brightest stars in our night skies.

Given the morphology of Markab (it is running out of hydrogen) it will ultimately become a giant orange star and rather than going supernova it will end its life as a white dwarf star after casting off its outer layers which will become a planetary nebula.

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.
