• TAKAHASHI FOA-60Q ORTHO APOCHROMATIC REFRACTOR with a 1.7x EXTENDER:

  The FOA-60Q is a new compact apochromatic fluorite doublet refractor from Takahashi.  The base telescope features a 60 mm aperture and a 530 mm focal length.  It has a 1.7x extender, which increases the focal length to 901 mm. 

  The spacing of the doublet elements is such that the correction of the spherical aberrations is similar to that found in the much larger TOA series.  This innovative design results in a Strehl ratio in excess of 96-percent for the base unit and over 99-percent with the extender.

    

  • Compact design for relatively long focal length, making it ideal for transport
  • Outstanding visual and photographic performance, providing a 44 mm diameter image circle for full frame imaging
  • Available with a 0.93x flattener

   

  Image Note:  FOA-60 OTA (without the 1.7x Extender -Q) Shown in use.  Mount, tripod, tube holder, and finder shown for use only and are not included.
