Description

A test with the medium format lens Mamiya 645 150mm f/2.8 A with aperture diaphragm f/3.5 on the OSC camera ASI6200 MC.
Green and blue appear in focus at the same time, unfortunately red is then slightly out of focus.
So here in the picture I tried to bring the red Stars to their senses  with a mask .
In an earlier test with the ASI6200MM mono camera, all the stars were round right down to the corners, provided the focus was refocused after each filter change.
I hope you like the picture given the short focal length.
