For those who have a refractor with a 100-120mm extension piece you can remove for bino viewing.
Instead of screwing the extension back in for single eyepiece use, or threading anything else into place.
Has anyone got a quick solution that you could do in the dark without too much hassle?
[ I am a fan of clicklock clamping as opposed to 3 screws - 120 degrees apart for tightening lol ]
I am considering getting 2 of these.........
I could install one, add the diagonal, add the second one and I'm still not too far away from the focuser.
or if the viewing height is low stick in the diagonal first.
47mm x2 gets me to 94mm and usually I have ample travel back on my focuser.
