Caldwell 9 - Cave Nebula

I tried to image many objects in this area this year. And after a nasty cloudy summer, i was grateful to image anything.
This nebula is a bit feinter than other things i'd done up to this point. So i had to image for a while longer. And i must say, it taught me something. As my integration times started approaching 20-30 hours, my images really started going to another level. I used to stop in the 4-10 hour range. But for my set up and bortle, >20 was a sweet spot to aim for.

Description: Reprocessed and became much happier with it. Noise is better controlled and i was able to bring some of the feint stuff up a bit. And as always, the stars are much better.

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.
