I have an MX that I want to use for astrophotography, and I understand it can take LX focusing screens. I would like to find an LX screen SD-11 (clear with etched crosshairs) but can't seem to find anybody selling them. If anybody knows where I can get one I would appreciate it.
Don't know about a New one, but B&H has a used one listed for sale at, $39.00
