Two Quite Different Aging Stars: Crescent and Soap Bubble Nebulas

This image includes two aging stars approaching the end of their lives. NGC 6888 is the bright Crescent Nebula at the top right which is energized by a Wolf-Rayet star (WR 136), a massive star which will end its life in a supernova. At the lower left you can see the Soap Bubble Nebula (PN Ju 1), a planetary nebula of a much smaller star, shedding layers as it nears the end of a much longer life. This planetary nebula was first discovered by amateur astronomers in July 2009.
The image was captured with 10.5 hours of exposures with a AT115EDT, the ASI2600MC, and the Antila ALP-T dual narrowband filter, using the CEM40, ASAIR+, and ASI OAG, with the ASI174mm mini for guiding. It was processed using APP and PS. I hope you enjoy this aging couple illuminating the night sky!

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.
