Product Description


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 altaz mounts. The dovetail bar also has 1/4" thread sockets for use with conventional tripod panheads. 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".
