75835 BT125-A
Discontinued January 2015
The BT125-A binocular features a pair of 125mm achromatic objective lenses at f6.1 and 760mm focal length. As with the BT81S, the 45° angled eyepiece holders make for comfortable viewing of the night sky or of distant terrestrial objects. The individually-focused eyepiece holders accept 1.25" eyepieces.
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".
