NGC6888 2022 07 06 10Sec S PS

07/06/2022
The new Optolong 1.25" L-Enhance Dual Narrowband Light Pollution Filter came in today, along with the usual clouds.
Figuring that it would be a few days until the next, predicted, fair night, I closed up shop and went home.
Around 8 pm the sky grew clear and 4 of the 5 major weather sites called for 1-20 % clouds.
Who can resist the urge to test out new gear?
So, back to the shop.
By the time the scope was set up I found out that I had been lied to again by the weather sites and the sky was 85 % clouds.
But, there were breaks in the clouds, so I captured through the gaps, as best I could.
I chose NGC 6888, The Crescent Nebula, as it was in the least cloud congested part of the sky.
I was only able to capture 145x10 second subs before the sky turned 100% cloudy.
Enough to see how the new filter worked.
I am really impressed with what the filter/camera combo managed to pull out of such a short session!
Posting 4 versions of the final image.
First one is from PixInsight, second one is from Astro Pixel Processor, the third one is APP’s version with reduced stars, and then cropped.
