NGC 6888 - The Crescent Nebula - is an emission nebula located 5000 light-years away in the constellation of Cygnus.

This image was taken on my Astro-Physics 130mm EDT f.8.35 APO telescope platform, which uses a ZWO ASI2600MM-Pro camera, and is supported by an IOptron CEM60 Mount.

12.9 hours of narrowband and RGB broadband data were collected for four nights ending on September 2nd.

This imaging project finishes up with the data collected on our last imaging cycle - let's hope the next one has good weather so I can collect some new data to work on!

The image was processed by using a Synthetic computed Luminance image and extensive use of starless processing workflows. The final image is a BI-COLOR Ha/O3 image with RGB Stars.

The full story behind this image, along with a detailed processing walkthrough, can be found at:

This video is a kind of experiment. While I cover the image processing done for an image in great detail in the web post, sometimes it may not be evident what the strategy is - and you may lose the forest for the trees. With this video, I am attempting to provide an overview of the strategy and flow and follow the images as they evolve through the image processing chain until the final image is achieved. I don't know if this attempt will work - so your feedback is appreciated.

Please consider supporting my fledging YouTube Channel by Subscribing and ringing the bell!

(Note: The video sequences with my face on them turned out to have a slight distortion in the recorded sound. My Apologies! Most of the video is just fine. Still trying to learn this video stuff!)

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.
