Located in Cassiopeia, NGC 7635 is a 7 light-year wide expanding cloud of hydrogen gas from the star, BD +60°2522. This star is classified as a type O star implying it is exceptionally hot and bright, with surface temperatures between 10,000 and 200,000 million times the surface of the sun. The energetic behavior associated with BD +60°2522 has resulted in layers of hydrogen gas being thrown off the surface of the star, expanding radially to form this characteristic bubble.

This target was shot in LRGB to try to highlight the highly active star field field surrounding the bubble. Some (way too much) hydrogen alpha was shot to help add some contrast and depth into the surrounding dust columns. We'll be shooting some Sii and Oiii data next year to present this target in a narrowband format.

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.
