Takahashi Sky 90 O.T.A.

$2,400.00



This model from Takahashi is a truly portable design. The 90mm (3") f/5.6 fluorite doublet apochromatic optical system is of outstanding quality, with a focal length of 504mm. The optical tube assembly is only 13.8" long, weighing 7 pounds; small enough for an airline 'carry-on'. Not only is this instrument an excellent choice for astronomy, it can be used as a portable high-quality telescope for birding. The oversized focuser is supplied with adapters for 2" and 1.25" diagonals, and accepts the FS series photographic adapters.
