NGC 7822 is a young star formation complex in the constellation Cepheus that includes an emission region designated Sharpless 171 and a young star cluster called Berkeley 59.
The SH2-171 complex also includes one of the brightest and hottest stars known to us, BD + 66 1673, which is an eclipsing system of two super-giants that exhibit a surface temperature of nearly 45,000K and a brightness approximately 100,000 times that of the Sun.
The "Little Rosette" nebula, also known as SH2-170, is the H2 region located in the constellation Cassiopeia. This region of gas and dust is about 7,500 light-years away in the Perseus arm of our Milky Way galaxy. The bright star in the nebula's center ionizes the surrounding hydrogen and causes it 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.
