Takahashi TOA-150B Refractor
The Takahashi TOA-150B is a premium 150 mm f/7.3 apochromatic triplet refractor designed to deliver uncompromising performance for both visual astronomy and astrophotography. Its advanced three-element objective features ED glass in both the front and rear lens elements, virtually eliminating spherical aberration while achieving outstanding color correction across the entire visible spectrum. The result is razor-sharp, high-contrast views with pinpoint stars and exceptional image fidelity.
Built for demanding observers and imagers, the TOA-150B features a precision 4-inch rack-and-pinion focuser with a 7:1 fine-focus reduction, a built-in 360° camera angle adjuster, and a retractable dew shield for easier transport. It is fully compatible with Takahashi's dedicated line of flatteners, reducers, and extenders—including the optional 67-series flattener, which supports an impressive 90 mm image circle for large-format imaging systems. An included tube weight helps balance heavy imaging or visual accessories, making the TOA-150B a versatile platform for serious astronomical observation. Please note: Tube rings, finder scope, mount, and tripod are not included.
