Ancient Bubble

NGC 7635 - As a child, I used to enjoy blowing bubbles outside on a warm spring day when there was a slight breeze. My mother would mix up some household dish washing detergent and water in a shallow dish which I would then dip into with a plastic ring. As I blew my bubbles, I would try to make the biggest bubble possible. Now, years later, I’ve captured this image of a “bubble” 7 light years across. Most bubbles are short lived, but not this one. Estimated to be 4 million years old, it will survive another 10 million years until the bubble's bright star, SAO 20575, explodes into a supernova. Using Drizzle technology at 3x, I was able to improve the resolution to reveal the bubble's web like detail. Over 25 hours of the very best subs were selected to produce this final image.
Acquisition Details: Esprit 150ED, ASIAIR, ASI2600MM, EQ8-Rh Pro, Astronomik 6nm SHO filters, 720 second subs at Gain 100 under Bortle 5 skies.

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.
