Focusing on the GG: am I missing some optical principle?

[Doremus Scudder]

Why not?

Just a little good-natured ribbing, Bob, since you post regularly about how important it is to get your loupe to focus on the frosted side of the ground glass. Not to detract from the importance of your advice, but it seems there might be a little wiggle room there after all, depending, of course, on how flexible your eyes are

Best,

Doremus

Sorry, there is no wiggle room. The distance from the top to the bottom of the gg is too great.
