Photoshop Version

I finished my polar alignment and my focusing on Altair and it was only 9:30pm, too early for the Soul Nebula in my location. So I did some research in Stellarium and found the Dumbbell Nebula was high enough in the sky but I didn't think my focal lenght of 447mm was long enough to image it. So I thought I would take a test shot and see what I could get and was very surprised at the result that showed up in NINA. I quickly created a sequence in NINA for the Dumbbell and began imaging. This is the processed version from Photoshop.

More data on Aug 19, 2021

I added another hour of data. Hopefully my post-processing skills also improved a bit.
