LEI 1.8x Tele-extender for APO For times when you need to get closer, Leica has developed the Extender 1.8x for Leica APO-Televid spotting scopes (angled viewing). In combination with the Leica Eyepiece, it yields 45-90X magnification. With this unprecedented expansion of the zoom range, wildlife, nature and astronomical observations as well as digiscoping become an even greater pleasure. An integrated, automatic lock on the bayonet connector allows quick and easy attachment of the extender between the spotting scope and eyepiece. The Leica APO Televid can then be quickly adapted to varied applications.
