GSO 6" f/4 Imaging Newtonian Reflector Telescope - Steel OTA (White)

Sales Tax Included

    The GSO 150mm (approx. 6") f/4 imaging Newtonian offers a fast focal ratio that's ideal for capturing wide-field images of hundreds of celestial objects. The short 600mm focal length keeps the tube length to a compact and easy-to-handle 21.75", making it straightforward to guide during extended exposures. With a total weight of only 13lbs-7oz (9lbs-12oz with OTA and focuser only) this scope is ideal for use with compact and precision equatorial mounts such as the Celestron AVX, Skywatcher HEQ-5, or Orion Sirius. And with a price that's far less than a small ED refractor or Ritchey-Chretien scope, this OTA offers an economical alternative for beginning and advanced imagers.
