Product Description
Skyoptikst 1.25" 45° Erecting Prism Diagonal – Correct Image for Telescope & Terrestrial Viewing!
This 45° erecting prism diagonal provides fully corrected, right-side-up images – perfect for both astronomical observation (Moon, planets) and terrestrial viewing (bird watching, landscape, sports). Unlike standard 90° star diagonals that produce mirror-reversed images, this 45° erecting prism delivers natural, correct orientation.
The 45° angle offers a comfortable viewing position, reducing neck strain during long sessions. Fits any telescope with a standard 1.25" focuser.

Important Note
💡 Perfect for: Bird watchers, nature observers, families, and astronomers who want a single diagonal for both sky and ground targets.
⚠️ For refractor telescopes only. Not suitable for Newtonian reflectors (which do not use diagonals).
⚠️ Never point your telescope directly at the sun – serious eye damage will result!
