BT 70 DL

Light weight 70mm binocular telescopes 45 deg. oculars





Description

Customers have been complaning that our long-range observation binoculars are just for men - what about the products for women who usually dislike the black, old-fashioned, rubberized look and want something much less heavier.  BT 70 DL is such a product - light enough, only about 3.6 kgs, pained body in white.  As all our binocular telescope, it has 45 deg. ocular and 1.25" focuser which accepts all the standard 1.25" eyepieces.

It comes with a pair of factory 16x eyepieces and alum case.  The fork mount and the alum tripod are optional.
