Crescent Nebula - NGC-6888 / Using Dual Band Filter

This has been a trying image for me and I know that its easy for everyone else. After my last one of the Crescent using my l-eHance filter I wasn't happy with the OIII data so I tried another filter (IDAS NBZ) recommended by a company (which will remain anonymous) and I wish I would have purchased the l-extreme now. That said the OIII is better with this image but still not what I wanted. I'm POSITIVE if a person with way more processing skills played with this data they could do way better but that's my limitations! I do think the star colors are better however.

Anyway the image was a struggle of 3-4 days (because of weather) of data totaling 5.8hrs of integration.

20 - 180sec frames

72 - 240sec frames

I used APP for the 1st time and was REALLY pleased at the way it worked once I figured out a few problems I ran into.

Finished up in Gimp for post processing.

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.
