Levenhuk Ra 150C Cassegrain OTA is a Cassegrain reflector that is perfect for observing deep sky. It features a distinguished design. The primary mirror is paraboloid and the secondary mirror is hyperboloid. Due to this, the transmitted picture has no spherical distortion across the entire field of view up to the maximum magnification. This Optical Tube Assembly (OTA) will be appealing to demanding and experienced users.

The optics are made of quartz glass with a silicon dioxide coating. The optical system has a reflectivity index of 92~96%. The dual-speed Crayford focuser has no backlash, so that it enables precise focus adjustments. The optical tube is made of steel, inside there is a high-quality blackening, and on the outside, there are two mounts: for the holder and for mount installation (dovetail plate). Levenhuk Ra 150C Cassegrain OTA is compatible with almost all of the modern mounts.
