These spherically and chromatically very well corrected 2-lens FCD SD binoculars offes an extremely high contrast. The 45° viewing position and the 1.25" eyepiece sleeves make this glass very universally usable. The 45° variant can be used terrestrially as well as astronomically. In the basic supply we have included a set of our 18mm UF eyepieces, you can change the magnification by changing the eyepiece sets. The focus position was chosen so that TeleVue Delos, Nagler, Panoptik and the Docter 12.5mm UWA eyepiece can be focused. This model is also available with a 90° viewing position. In this equipment variant, we deliver our stable 1-arm center mount, which enables mounting on a tripod and allows longer observation sessions.
Slidable dew shields with front cover, a handle with sighting device, a photo tripod adapter with 3/8 "thread connection and 2 eyepieces with 22x magnification are integrated. With the UF 24mm eyepieces, the magnification is i.e. 17x.
