Vario-Okular D 15-56x/20-75x

All eyepieces have a quick-change bayonet fitting with safety lock and can be attached to both the 65mm and the 85mm spotting scopes. This results in different magnifications, 15-56X for the 65mm and 20-75X for the 85mm spotting scopes Especially practical zoom eyepiece: - small magnification for an overall view and for finding the object, then zoom in for more detail. - no refocusing necessary when zooming from high to low magnification. - still gives a bright image at twilight at lower magnifications (large AP) Note: This eyepiece fits all DiaScope spotting scopes. However, the bayonet connection locking mechanism works only with the newer 2010 DiaScope spotting scope models!
