Levenhuk Ra 150C Cassegrain OTA Telescope

Levenhuk Ra 150C Cassegrain OTA is a reflector with Cassegrain design that is ideal for deep sky observing. It has an outstanding design. The primary mirror is paraboloid and the secondary mirror is hyperboloid. Thanks to this, the transmitted image does not have spherical distortion throughout the entire field of view, even at maximum magnification. This optical tube (OTA) will please experienced users with demanding needs.

The optical elements are made of quartz glass with a silicon dioxide aluminum coating. The optical system has a reflectivity index of 92~96%. The dual-speed Crayford focuser is slack-free, allowing for precise focus adjustments. The optical tube is made of steel. Its interior has high-quality blackening, and on the outside there are two supports: for the eyepiece holder and for installing the mount (dovetail plate). The Levenhuk Ra 150C Cassegrain optical tube is compatible with almost all modern frames.

Attention: The mount, tripod, finderscope and eyepieces are not included in the kit. Some recommendations are made under the description. If you have any questions, contact our customer service center.
