Neewer 1.25" 45-Degree Erecting Diagonal

Enjoy a comfortable posture when stargazing with your refractor or catadioptric telescope with the 1.25" 45° Erecting Diagonal from Neewer. The diagonal slips into a 1.25" telescope focuser and accepts 1.25" eyepieces, angling them upward at 45°. The diagonal's prism features antireflective multicoating for maximum light transmission, so the view is bright and sharp with good color fidelity. It also allows your telescope to be used for terrestrial viewing, since the prism produces an image that's right-side up and left-right correct with refracting and catadioptrics.
