Celestron 1.25" 9 mm RK Eyepiece
This eyepiece is a true insiders´ tip if it comes to planetary observation or double star observation at medium magnification. The view is clearly more convenient than the one fo a Plössl eyepiece with a similar focal length. Even beginners will have no problems to overlook the field of view. However, the eyepiece uses only 3 elements. Correspondingly good are contrast and also image brightness.

Teleskop-Service recommends the RK9 to all amateur astronomers who are searching for a simple, but powerful eyepiece for medium magnification. The eyepiece can be used with all popular telescopes with 1.25" or 2" focuser.

RK eyepieces are a derivative of the classical Kellner. Compared to the Kellner, the sharpness in the field is improved. The view of RK eyepieces is also very comfortable, too.

RKs are a good choice for amateur astronomers wo are searching for a low priced and versatile eyepiece. The comfortable view makes RK eyepieces a recommendation for beginners. The RK is well suited also for centering and guiding.

The RK eyepiece has a rubber eye cup which prevents lateral stray light from entering. It is foldable for spectacle wearers.
