In combination with spotting scopes and the Leica eyepiece, the Extender 1.8x enables a previously unheard 90-fold 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 1.8x between the spotting scope and eyepiece. The rubber-armed functional elements and comfortable eyecup provide excellent grip and pleasant viewing conditions. Handling of the eyepiece remains precise even when wearing gloves. Only to be used with angled spotting scopes.
