The Meopta MeoStar Binocular Tripod Adapter is one of the very best tripod adapters available, because of how speedy it is to use.
It allows you to attach MeoStar binoculars, as well as most other
binoculars with a 1/4"-20 threaded tripod socket, to any tripod head
with a 1/4"-20 threaded protruding screw. Its advantage is that the
upper portion of the adapter remains attached to your binocular's tripod
socket, facilitating significantly quicker attachment/detachment from
the tripod head. No more fumbling to align and twist a
screw-and-threaded-hole connection. The piece remaining between your
binocular's objectives doesn't get in the way of your observing nor
lengthen the binocular's minimum interpupillary distance setting.
