Very nice processing! Is everything correct with the corrector segment? Because I also have such a quad, and I just can't fix the stars in the corners, even though the collimation is fine. I'm already starting to suspect it's made in China for Russia.

Thanks! The corrector is screwed onto the T-ring M48, and the back focus seems to be properly set.)
