- Produces a large 44 mm image circle for astrophotography.
- Available with a 1.7x extender in the FOA-60Q package.
Simple and Unique High Visual Performance Doublet Refractor
The Takahashi FOA-60 is a compact yet remarkably refined apochromatic refractor, designed to deliver big-scope optical performance in an ultra-portable form. Built around a precision 60 mm fluorite doublet objective, the FOA-60 uses an innovative element spacing that achieves spherical aberration correction comparable to Takahashi’s much larger TOA series. The result is exceptional contrast, razor-sharp detail, and a Strehl ratio exceeding 96%, making this telescope equally impressive for high-resolution visual observing and demanding astrophotography—whether at home or on the road. Note: Mount, tripod, tube holder and finder not included.
