NGC 6888, Crescent and Soap Bubble HOO

Took an hour of Ha in early August. Last night was a bonus clear night and was able to gather quite a few subs for this, while the Moon appeared high up in the opposite part of the sky. Managed to get the Soap Bubble in the same frame in the bottom left corner. I haven't over stretched the OIII data for the outer shell, yet! Hopefully I'll get to add some more subs on this before Cygnus gets lower in the sky.
It's been quite a few years since I last imaged the Crescent Nebula, certainly one of my first images on Astrobin.

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.
