45-degree BT 100 on fork mount is the long-awaited 45 degree version of straight-through 25/62x100. This is by far the most user-friendly binocular specifically designed and made for amateur astronomers - hopefully, the 45-degree together with the new factory fork mount will get rid of the back and neck strain while the users pointing the binocular all the way up to the zenith.

The same as 25/62x100, the non-proprietary 1.25" helica focuser is used to accept all standard 1.25" eyepieces - this is the major difference from 20/26/32x88 with the proprietary focuser which only accepts the factory eyepieces 20x, 26x and 32x.

The binocular comes with a wooden or aluminum tripod, the fork mount, a pair of factory 25x eyepieces and a traveller-style carrying case. The optional accessories include the 7x50 finderscope. The 15x, 40x, 60x and 125x eyepieces are under development and will be available in this June.
