1.25" star diagonal for telescope 90 degrees erecting
Fits telescopes with 1.25" focusers or visual backs, 90° viewing angle, best for observing objects overhead.
Accepts standard 1.25" eyepieces, Barlow lenses, and other accessories with a 1.25" insert barrel.
The diagonal is threaded for 1.25" filters.
The 1.25" Star Diagonal slides into the focuser (1.25") of your refractor or catadioptric telescope and accepts standard 1.25" eyepieces, allowing you to view objects more comfortably.
A diagonal that is angled at 90° helps avoid neck strain when looking through through the eyepiece.
Please note that a 90° diagonal will display images that are right side up, but left to right orientation will be reversed.
