Takahashi TOA-130NS 5" Ortho-APO Triplet Refractor
with 2.7" Rack & Pinion Focuser

The Takahashi TOA-150B is an amazing refractor that screams quality! Below is a list of key features pertaining to the Takahashi TOA-150B

  • The Takahashi TOA-130NS is ideal for both visual and photographic applications
  • The TOA-130NS is an Ortho-Apochromat with a "Double ED" triplet design that produces the highest level of color correction
  • Takahashi TOA-130NS comes with a dual speed 2.7" rack & pinion focuser
  • This Double ED Triplet has 1/12th wave accuracy and an airy-disc Strehl ratio of 0.992
  • Full 5 Year Manufacturer Warranty

Featuring a uniquely designed triplet that uses special elements to produce the highest of color correction, the TOA-130 is ideal for both imaging and visual astronomy. The TOA design consists of three elements just like any triplet, but the front and rear elements of the TOA telescopes are constructed from FPL-35 Extra Low Dispersion glass for stunning clarity and resolution. Takahashi engineers have taken great pains to eliminate spherical aberration while keeping axial chromatic aberration to a minimum in the visible light spectrum. In fact, the TOA design produces less than 1/100th the aberration of a typical apochromatic design!

The lens cells on the TOA-130 are carefully constructed and are capable of withstanding transport. They also allow for collimation if the owner wishes to make adjustments. With 1/12th wave accuracy and an airy disc Strehl ratio of 0.992, the optics on the Takahashi TOA-130NS Ortho-APO are as near to perfection as you can get!

The Takahashi TOA-130 Ortho-APO is very appealing to users who wish to use full frame or medium format cameras. Included with the TOA-130 is a heavy-duty dual speed 2.7" rack & pinion focuser that produces a usable 40 mm diameter image circle for virtually non-vignetted 35 mm prime focus photography. To ensure no image shifting, the TOA-130 is equipped with a large thumbscrew that locks the focuser tube in place. To allow the use of additional accessories, the focuser itself offers a generous 222.5 mm of back focus.

Long enough for high magnification of the moon and planets, the TOA-130 has a native f/7.7 focal ratio with a 1000 mm focal length. This superb double ED triplet refractor produces images with saturated color and amazing contrast due to its high order of color correction. The TOA-130 is packaged in a compact 40" tube (with the dew preventive lens shade retracted) that weighs only 23 lb. Overall, the TOA-130 is another fine, high-quality instrument by Takahashi.
