Lacerta Pentaprism 1.25" (90 deg)

The Lacerta pentaprism has an astronomically correct image, so the image is inverted (as if you are looking into a telescope). There is a distinct advantage over a star diagonal that requires mirrored maps. Compared to the Amici prism, a pentaprism usually offers a better imagee with great contrast on bright objects and high magnifications.

Optically and mechanically, the prism is at a high level, the 5-sided prism is made of BK-7 glass. For maximum light transmission it is made with fully multi-coating. The 1.25 " barrel has a filter thread, the eyepieces is fixed with a clamping ring.
