We are currently being a Vendor at Black Forest Star Party in Pennsylvania! Shipping will resume with our return on Monday! Come by the vendors tent and say hi!!!
Ortho-Apochromat, not just apochromat. The Triplet Ortho-Apochromat design, built around a highly air-spaced ED triplet with two S-FPL53 elements, completely eliminates spherical aberration while delivering the best chromatic correction in the entire Takahashi lineup.
Sharp planets, deep skies, same telescope. That optical formula lets the TOA-130NFB excel at high-resolution planetary work and deep sky imaging alike, fully exploiting the capabilities of today's largest camera sensors.
A focuser built for serious payloads. An oversized 4" (102 mm) rack-and-pinion focuser with a 1/7 microfocuser delivers the fine control heavy imaging trains demand, backed by a CAA (Camera Angle Adjuster) ring for effortless photographic framing.
Ready to find what you're aiming at. The built-in FQR-1 base accepts a 7x50 finder scope, so locating targets stays simple even with a 130 mm aperture up top.
Go wide, go deep, or go long. Pair it with the TOA-35FL field corrector for native-focus imaging, the TOA-35RD focal reducer for faster deep sky work, or step up to the 67FL super-corrector for a massive 92 mm image circle, giving this one tube serious range.
Packs smart despite the size. A retractable dew shield shrinks the tube from 1155 mm down to 1022 mm for storage, keeping a 130 mm apo as manageable as a scope this size can be.
Resolutely turned toward imaging. Every element of the TOA-130NFB, from the focuser to the finder base, is engineered to support the heaviest photo setups without a hint of mechanical strain.
