A wide angle eyepiece for a higher magnification to Swarovski ATS/ATM 80 and ATS/ATM 65. Will also fit perfectly to the old Habicht At80. The eyecup is of twist-type, with a rubber cover which is integrated with a thread around the eyepiece. The unit is waterproof also when not mounted on the spotting scope.
A very good alternative if you seek a little bit higher magnification without the zooming function. All this without loosing any light or field of view, as the zooming eyepieces unfortunately can cause.
