NGC7822

NGC7822 is a young star forming region in the constellation of Cepheus, and this is the last image that was taken with my TOA-150. Frankly, not my favorite nebula, but it does have one interesting thing about it. Namely, the star TYC4294-6-1. This eclipsing binary contains an O5V star that is one of the hottest discovered within 1kpc of the sun, with surface temperatures of nearly 45,000K and 100,000 times the luminosity of the sun. It is one of the primary stars illuminating the nebula and is shaping the column like formations directly above it in this image. I have shown the location of TYC4924-6-1 in the mouse over image.

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.
