NGC-6888 The Crescent Nebula and the Soup Bubble Nebula

The Soap Bubble Nebula, or PN G75.5+1.7, (Above and to the left of NGC-6888 in the image).
Is planetary nebula in the constellation Cygnus.   It was discovered by amateur astronomer
Dave Jurasevich using an Astro-Physics 160 mm refractor telescope with which he imaged
the nebula on June 19, 2007, and on July 6, 2008.  Its distance is estimated at 4500 light-years.

The Crescent Nebula NGC-6888 is about 5000 light-years distant.

This image is a combination of data that I took on Nov 2021 (3 hours and 25 minutes) and
the remainder of data on Oct 14, 2022. My goal was to get the Soup Bubble in the image.
With the 2021 data it was barely visible only if you knew where to look. Adding the 2022 data
especially with 10 minutes exposures, that brought it out.

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.
