M27 Aflutter in HOO

Large in apparent size and one of the more magnificent planetary nebulae in the sky, M27 is called the Dumbbell Nebula due to a dumbbell shape that's prominent in the eyepiece. I was really surprised how much extra gas was revealed beyond what one sees visually.

As it's located in the constellation of Vulpecula, it sits in a very dense starfield (the Orion Arm of the Milky Way to be specific), so I pulled the stars way back to bring focus to the nebula. The most attractive feature to me are the enormous tubes of doubly-ionized oxygen (blue) that encircle the core. OIII in this form has such a soft look to it that really adds an ethereal texture to this nebula.

The reduction of the bright center core was a challenge to me. This took me a long time and several tries in processing to get it to this point. I'll no doubt try it again some time later as I continue to learn PixInsight.

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.
