With apologies in advance to those who work only in brass, I removed the scope from my Nitto sextant, installed duct tape, put two 1/16" (1.6 mm) holes as far apart as I could, and looked at the full moon last night. I couldn't see any difference through the hole near the frame versus the hole further out.
The Nitto is a bit odd in that its horizon mirror is half mirror and half nothing so there is no glass between my eye and the horizon. Even looking at half nothing and half reflected moon at the same time from either hole - no difference that I could see.
I'll try again with my Davis sextant to see if the clear glass makes any difference.
Regards, Noell
