Crescent Nebula -or- The Brain from Planet Arous

Revision title: More OIII shell

Those unfamiliar with the joys of 50s-era "B" sci-fi movies are going to have to Google that. (OK here's a link)

Shooting through a heat dome in the PNW was pretty wavy but shooting straight up helped. Shot 125 each Ha and OIII and some RGB for stars over three nights. Processed Yuan HOO (and straight HOO) with RGB stars added in. I left a lot of stars as the size of the nebula seemed able to support it.

SkySafari describes it as an outwardly moving star-shedding envelope colliding with an inwardly moving envelope the star shed much earlier. Or is it really The Brain from Planet Arous coming to take over our minds!!!!!????

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.
