Levenhuk Ra 250N F4 OTA is a Newtonian telescope with a 250-mm primary mirror and a focal length of 1000 mm (f/4). This model is best-suited for astrophotography. The telescope tube is made of metal, following a more traditional design.
This telescope is fitted with the modern 2" dual-speed Crayford focuser. Linear ball bearings of this focuser provide for additional stability, and further reduce backlash. The 2'' focuser allows you to use accessories - including coma correctors - from other manufacturers, reduces vignetting and allows you to attach your camera with ease.The telescope tube has a built-in primary mirror cooling fan. Even though Levenhuk Ra 250N F4 OTA was designed with astrophotography in mind, it still performs wonderfully during celestial observations.
