Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

This was a real ghost! After three nights fighting with the moon, ice on the camera sensor cover glass and other technical problems, I got at least enough data to process it. Also I had to shoot with gain 100 in RGB, which is rather uncommon, but the signal was so faint due to light pollution, since other wise nothing would have been visible. My location is definitely not the best place for dark nebula. But if you never try, you will never find out...

Since this is my very first try to go for a dark nebula I have noticed how hard it is to achieve a decent result. The raw data is definitely by far better than the actual result, but I am still figuring out the right approach.

Maybe I get the chance to add some data in a later session, but the whether forecast is less optimistic.

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.
