Image recorded during windows of clear sky on the nights of 21, 26, 27 November  and 13 December 2022, and matched here with a spectacular infrared image from Spitzer Space Telescope. It is interesting to see how different are the two images, with the infrared ability penetrate dust, and the stars showing different relative luminosity.
I applied 2x2 drizzling in order to avoind pixelated stars from under-sampling.

Sh2-199 - Radio Source W5
Often called Soul Nebula, the infant-shaped Sh2-199 is ionized by stars belonging to the IC 1848 cluster and is also the location of the radio source W5. Like the nearby Heart Nebula (Sh 2-190, not visible in this picture) and surrounding smaller nebulae, Sh 2-199 is embedded in the Cas OB6 association.
Kharchenko gives a distance of 2002 parsecs and an age of 4.4 million years for IC 1848 and lists 5 ionizing stars: HD 17505 (O7, although SIMBAD gives an O6Ve class), HD 17520 (O9V), HD 237019 (O8V), HD 237007 (B0V), and HD 237011 (B2, although SIMBAD gives a slighter hotter B1.5 class).
Avedisova places Sh 2-199 and Sh 2-201 in star formation region SFR 137.57+1.08, with 65 components, including 16 infrared sources, 2 masers and 4 young stellar objects.

Comment to Spitzer Image - Image credit: NASA/JPL-Caltech/Harvard-Smithsonian CfA
Generations of stars can be seen in this infrared portrait from NASA's Spitzer Space Telescope. In this wispy star-forming region, called W5, the oldest stars can be seen as blue dots in the centers of the two hollow cavities (other blue dots are background and foreground stars not associated with the region). Younger stars line the rims of the cavities, and some can be seen as pink dots at the tips of the elephant-trunk-like pillars. The white knotty areas are where the youngest stars are forming. Red shows heated dust that pervades the region's cavities, while green highlights dense clouds.
W5 spans an area of sky equivalent to four full moons and is about 6,500 light-years away in the constellation Cassiopeia. The Spitzer picture was taken over a period of 24 hours.
Like other massive star-forming regions, such as Orion and Carina, W5 contains large cavities that were carved out by radiation and winds from the region's most massive stars. According to the theory of triggered star-formation, the carving out of these cavities pushes gas together, causing it to ignite into successive generations of new stars.
This image contains some of the best evidence yet for the triggered star-formation theory. Scientists analyzing the photo have been able to show that the ages of the stars become progressively and systematically younger with distance from the center of the cavities.
This is a three-color composite showing infrared observations from two Spitzer instruments. Blue represents 3.6-micron light and green shows light of 8 microns, both captured by Spitzer's infrared array camera. Red is 24-micron light detected by Spitzer's multiband imaging photometer. For reference: visible spectrum ranges from 0.4 to 0.7 micron.
