A holder for at least one eyepiece is described. The holder includes an upper plate having at least two upper apertures therethrough, a top surface, and a bottom surface, and a lower plate having at least two lower apertures therethrough, a top surface, and a bottom surface. Each lower aperture corresponds to one of the upper apertures of the upper plate. When the upper and lower plates are mutually aligned, the at least one eyepiece may be inserted through corresponding upper and lower apertures. Furthermore, 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 to retain the eyepiece in the holder.
