Description

I have tried to catch a large area around NGC6888 with my Esprit100 plus Riccardi reducer on full format 24x36. I failed because of heave astigmatism and coma in all four corners. But the center part, about APS size was not too bad - not perfect in the corners still, but quite impressive and a smaller part of it is that image here.

Camera was Nikon D850 at ISO 800, 100 subs at 120sec each. One night...from almost from astronomical dusk to dawn..
