Description

Continuing my journey in alt/az imaging.

I learn more and more about how to best guide my motorized SkyTee2 mount - aka "Omegon TwinView AZ" and "TS-Optics AZ5" in Germany. This time it guided within 1.5" for over two hours. In my seeing this means I am only limited by field rotation. The only subs I had to discard were the ones with tree-tops reaching into the image.

This is over 12 hours of exposures using my 25-year old C8, Celestron's 0.63x Reducer and my unmodded Nikon D3400.

Pretty happy. There's some noise still visible, but not overly. Gradient removal was tricky. But I got good flats for the first time with my C8.
