Bynolyt Tern 10x45
The Bynolyt Tern 10x45 provides very clear, sharp images and image errors are history thanks to the use of lenses consisting of four glass components. The lenses and prisms have undergone a multi-layer coating process and image distortion is minimised. This Bynolyt Tern 10x45 performs well throughout the night.
Grip
The Bynolyt Tern 10x45 is comfortable to hold, thanks to its soft rubber covering and the thumb notch on the bottom. The good grip is enhanced by the pleasantly low weight. If you would like to use a tripod: the viewer has a tripod socket.
Additional information
The central focus works smoothly and this same mechanism also corrects differences in eyesight. The correct setting can be locked.
