Caldwell 27 - Crescent Nebula (NGC 6888) - Bicolor

First attempt of a bicolor with data shot by my own new OIII filter! Quite fiddly to get the channels aligned in PI. In the end I saved the stretch and pre processed images and did the bicolor composition in PShop.

Also tried to do the sharpening solely with the APF-R technique, quite stunning how much detail you can get out without introducing any noise. If you are interested here is a very good site about that topic: http://www.cedic.at/apfr/

Let me know what you think!

Description: Just for fun the annotated version, I wanted to know some of the background stars and maybe even see if I can see the core of the Wolf-Rayet Star WR 136 who is responsible for NGC 6888

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.
