Mirror diagonals are well known for superior performance over prism diagonals, but they are typically a high cost item. This is not the case with these fine diagonals from Arcturus! These mirror diagonals use a top quality first surface mirror. Includes dust cap.

Fits telescopes with 1.25” focusers or visual backs, 90º viewing angle, best for observing objects overhead.

Accepts standard 1.25” eyepieces, Barlow lenses, and other accessories with a 1.25” insert barrel.

Please note that a 90º diagonal will display images that are right side up, but left to right orientation will be reversed. The Arcturus 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 90º helps avoid neck strain when looking through through the eyepiece.
