Hi Anthony,

Thanks for sharing. Looking at what you guys are doing helps me learn the
program and the optics.

Perhaps this is because the light spends more distance in a tilted lens?

I've been messing with John Upton's Ross Null setup. I find that defining
different autofocus methods also changes the focus a bit.
