Pacman Nebula - NGC 281 Dual Narrowband

I used my dual narrowband (IDAS NBZ) filter to shoot this over a 2 night period. I processed it in APP using the Ha/OIII Color algorithm and calibrated the background. All other post processing was done in Gimp.

Seeing: 3/5
Transparency: 1st night 4-5 / 2nd night 5-5
Bortle 4.2

I like this version but I'm working on another variation that has a different color appearance to it due to a star calibration tool I used. I don't understand how it changed the color so drastically but I kinda like what I see so I'm moving forward with it and will post it. Stay tuned!

Thanks for looking!

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.
