I was driving from one job site to another today and had this probably crazy idea of adding some crosshairs to my 35mm Panoptic so that it could actually be used for alignment.
What I had thought of would be getting a cheap 2" clear filter and gluing a guitar string into a +, this could then be threaded into the bottom of the Panoptic.
Now the rational part of me says that it is too far away from the entry/exit pupil of the lens to be able to see the cross hairs, but is it? Or will I just get nasty/irritating diffraction patterns?
I'd test it but the only clear filter I have is an unmounted 36mm Astrodon L filter which I am not inclined to glue a guitar string onto
