Claim:
A holder for at least one eyepiece, comprising: an upper plate having at least two upper apertures therethrough, a top surface, and a bottom surface; a lower plate having at least two lower apertures therethrough, a top surface, and a bottom surface, each lower aperture corresponding to one of the upper apertures of the upper plate, where one of the plates is selectively slidably fixed in one dimension with respect to the other plate; a lock mechanism for locking the relative position of each plate; whereby when the upper and lower plates are mutually aligned, the at least one eyepiece may be inserted through corresponding upper and lower apertures, and when one of the plates is selectively slid with respect to the other plate, the upper and lower apertures become misaligned to bind the at least one eyepiece in a secured position to retain the eyepiece in the holder, the lock mechanism locking the relative positions of each plate in the secured position.
