TS Optics TSELR1 Erecting Lens 1,5x - 1,25 inch for reflector telescopes

Each refractor shows an upside-down image with sides mirrored if it is used in direct vision (without star diagonal).

With these accessories, the image is upright again and, if an Amici prism is used, not mirrored anymore. On the other hand, view has a 90° angle or, with Amici prisms for terrestrial use, a 45° angle instead.

Especially when viewing at daylight, one oftens wants to look into the same direction as the telescope. The TS Erecting Lens solves this problem and you have a correct image orientation in your telescope, but without angled insight.

The TS Erecting Lens also works great with nearly any other type of telescope, apart from Newtonian telescopes, for which we offer a separate solution. At Schmidt-Cassegrains, Maksutov telescopes and refractors, it even replaces the star diagonal. That is useful if you want to view straight trhough the telescope. Here, it also offers a correctly orientated image where up is up and left is left.
