The Bubble Nebula

Widefield Bubble Nebula. An emission nebula in the constellation Cassiopeia.. I am happy I was able to fit both NGC 7654 and M52 in the same frame. I left the final image at full size, opting not to re-size the image in processing.

From Sky Safari;

“NGC 7635 is about 11,000 light years away. The "bubble" in NGC 7635 is about 10 light years across. It was created by a fierce stellar wind from the hot, young, massive central star, which has blasted out the structure of glowing gas against denser material in a surrounding molecular cloud. The nebula is being energized by the hot central star, causing it to glow. The central star SAO 20575 is thought to have a mass of 10-20 solar masses.”

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.
