binoviewers

Post by skyhawk »

I have w.o binoviewers, I also have binoculars which I have NO problem adjusting

Can anyone advise why it is that for some reason when I have 100% perfect focus on the left I am unable to get the right side to go "in" enough, it comes to the end of travel just mm from screwing down enough, help appreciated.

Your eyes have different dioptre correction and/or the light path length can differ both sides depending on binoviewer design.
Beamsplitter?

It might work with a Barlow or different eyepieces.

Or possibly if you wear glasses, or take them off if you normally wear them.

Forget it, I am a MORON, I didn't know you can adjust BOTH sides unlike binoculars

Many binoculars are independent eyepiece focus rather than centre focus.
Particularly military and marine ones.
