The Italian sky does not allow the use of very large telescopes. We have a seeing and a very high light pollution. I chose two specialized telescopes to fit in a single mount.
In the future I think of a 350 mm f 14 with classical cassegrain reducer and flattener, I'm talking to the manufacturer.
I'll put a video where you can also see the 350 mm with the cells.
