The screenshot is a little lackluster but the video below shows it off better. The camera is an APSC sensor but the picture fills a full frame with very little vignetting. Up to 100x it looks pretty good but yeah, the DoF is literally micrometers thick.
I took this approach as well but I let Grub add Windows as a boot option. No mashing keys at post and Windows doesn’t get to touch Grub or Debian.
