FireWorks on the 4th, NGC6946

Kind of a coincidence that I finished this project today on the 4th. I've been tweaking my camera sensor tilt plate for the past 6 nights while imaging this target. I'm finally got it figured out. My EFW is the main part of the problem, but thanks to Tom Gray's suggestion to use ASTAP (which works on my Mac!), I've adjusted to an acceptable level. I now have another step in my setup process each night! In this image, I blended Ha to the red channel before channel combination of RGB. I used just a tiny bit of Topaz Serere Noise setting of 5 for remove noise, 15 for recover original detail, all other settings zero. I used only 60% of my subs...I have 6 full nights worth!

So happy 4th of July to all in the USA, but all of us in the world blessed by having freedom need to give thanks and work for justice for all on the earth.

L 80x300, RGB 42X300 each, Ha 25x300

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.
