NGC6888 / Sh2-105 (CYG) The Crescent Nebula - Where is my mind …

Summer nights aren’t astronomically dark, but I couldn’t resist in going after the crown jewel in Cygnus, the Crescent Nebula. Captured in Ha and Oiii, just before the moon glow would start to wash out the Oiii. A revisit of this DSO from year ago but this time with a bit more experience. It’s captured and processed in HOO, with a squeeze of rgb-like colours. Surprisingly, there is a lot more Oiii in the surrounding area, instead of only the veiled shell that surrounds the crescent.
Two images, a full version and a cropped (1/2), showing the crescent up close.
Happy to see the detail on the Oiii outflow around the crescent, and the details of the supernova remnant. It’s as if you can see the turmoil whirling around.

Happy with the outcome of 11 Hours of data. Although my processing has advanced over the last year, I still feel that this image could’ve been brought to a higher level, maybe I’m setting my quality bar too high (or not high enough). Anyway … true to my life’s principle: by reaching for the impossible, we achieve the improbable. Glad with what I’ve achieved on this one … so far …

Clear Skies everybody! 🤩✨🔭

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.
