This 81mm astronomy binocular delivers crystal clear, sharp views through its new optical design. Its lightweight body ensures that you can take it to any observing location.
The air-spaced doublet optics in this 81mm are magnesium fluoride coated to help reduce the effects of chromatic aberration.
Mounting the binoculars is a simple process as they come supplied with a Vixen dovetail mounting bar for use with equatorial or alt-az mounts. The dovetail bar also has 1/4" thread sockets for use with conventional tripod pan-heads.
An optional altaz fork mount is available and allows the binoculars to be used on the optional SX-HAL130 or SXG-HAL130 tripods. These provide a stable but lightweight tripod base for this excellent "space binocular".
