Leica Televid 25-50 WW Variable Eyepiece 41021
Leica Televid 25-50 WW Variable Eyepiece 41021, Leica's 25-50x WW Aspherical Eyepiece for their 65mm and 82mm Televid spotting scopes is an exciting watershed device a reason unto itself to choose Leica over the other premium brands.It is the first zooming telescope eyepiece which has a wide angle of apparent field of view throughout its zooming range instead of exclusively in the higher-magnification range as is the case with other zooms. The apparent field here goes from 59 to an astounding 80deg surrounding your eye with a view that is only more vast in a handful of fixed-magnification extreme wide angle specialists in the astronomy realm.Despite this eye relief maintains a constant comfortable distance of 19mm.Like any modern eyepiece it has a rubber armored body with helicoid-style eyecup and like all Leica eyepieces it is nitrogen filled and individually tested to assure its watertight status. * World's first zoom eyepiece with wide angle viewing at all magnification levels * Light silent and durable rubber-encased die cast magnesium housing * Leica's hydrophobic AquaDura external coating sheds moisture resists dust and debris and cleans easily * Extreme temperature operating range * Simple click-locking bayonet fitting * Broad turning style soft rubber eyecup * Individually tested to be watertight at 5 meters * Directly accepts Leica's Digital Adapter 3 for simple low-mass digiscoping
