NGC6888 - Crescent Nebula in HOORGB

Another one of my favorite objects, NGC6888 is formed by the stellar winds of WR 136 colliding with the slower moving stellar winds from this star when it became a red giant 250,000 to 400,000 years ago. Because it is nestled right in the constallation of Cygnus, there is plenty of beautiful nebulosity surrounding the crescent. I wanted to feature that nebulosity, explaining (I hope) my unconventional framing around the object. I always liked the Crescent in HOO, but I really dislike HOO star colors, so I decided to shoot RGB stars and include them in the image.

It's great to have my TOA-150 back up and running again. This is my first complete image taken from the amazing skies of the Sierra Remote Observatories.

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.
