45-degree BT 80 follows basically the design of BT100 45 degree: its 1.25" non-proprietary focuser accepts all industry standard 1.25" eyepieces.  It uses a doublet objective design, but by using the best optical materials and the latest machine tools for the glass grinding, it has excellent optical performance. Due to its much lighter weight than BT100 45 degree, BT80 45 has more mobility and is easier for a quick set-up.

45-degree BT 80 comes with a wooden tripod or alum tripod, the fork mount or the normal mount, a pair of factory 20x eyepieces and a carrying case.  The optional accessories include the 7x50 finderscope.
