Takahashi TOA-130NFB Ortho APO Refractor
130mm f/7.7 with 4" Dual Speed Rack & Pinion Focuser

The Takahashi TOA-130NFB Refractor has a unique Ortho-Apochromatic optical configuration. 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-53 Extra Low Dispersion (ED) 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! With an airy disc Strehl ratio of 0.992 and 12th wave accuracy, you will be delighted with your views! 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.

The Takahashi TOA-130NFB is a dream come true for both visual astronomers and serious astrophotographers. The NFB model includes a 4" dual speed rack and pinion focuser with a built-in camera angle adjuster. This camera adjuster allows the astrophotographer or observer to turn the camera or eyepiece 360 degrees. This flexibility helps place an image at its most pleasing angle and is especially helpful for astro-imagers. The TOA-130NFB focuser offers a generous 274.5 mm of back focus, 7:1 fine focus capability, and a beefiness that will handle the largest cameras with ease.

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 27 lb. Overall, the TOA-130 is another fine, high-quality instrument by Takahashi.
