sectional view of a "brain" - NGC6888

Crescent nebula looks more like a brain to me, a brain structure surrounded by blue nerves. It is not an easy target with so much details and lot of gas around. Not to mention how faint the O3 signal is. I shot it over two months because of weather and issues with my Moravian 16200. The first issue was that I accidentally blew out the fuse and shortcut a zenner diode on power board. After I fixed it and completed the session, the mechanical shutter blade fell off:-)

This is my second try on NGC 6888. This time I shot it with much longer subs. That's a big advantage with CCD camera.

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.
