1.25-Inch 45-Degree Telescope Diagonal Prism

Change the eyepiece viewing direction on a matching refractor telescope. This diagonal prism provides a 45-degree viewing arrangement for a compatible 1.25-inch setup.

✅ View from an angled eyepiece position - The diagonal changes the viewing path rather than requiring a straight-through position behind the tube.

✅ Use a matching eyepiece format - The 1.25-inch fitting gives a defined interface to compare with the telescope and eyepiece.

Check the Telescope's Focus and Fitting

Use the prism only where the focuser and eyepiece match the actual barrel dimensions and optical arrangement. Available focus travel must accommodate the diagonal in the telescope.

The selection supplies one prism accessory rather than a telescope or eyepiece. Its role is to change the viewing path within a compatible observing setup, not to add magnification on its own.
