The Takahashi FOA-60Q refractor was designed to provide a compact instrument capable of delivering exceptional visual performance, similar to that achieved by the TOA series, a true benchmark in this field. Equipped with an apochromatic fluorite lens doublet at an F/D ratio of 15, the FOA-60Q will satisfy the most demanding amateurs. It remains very light, with a weight of only 2.4 kg, and very compact thanks to its retractable dew shield.
The FOA-60Q is simply the best scope in the Takahashi range, with its theoretical Strehl ratio of 99.8%, higher than those of the TOA-130 and TOA-150. The integrated Extender 1.7X can be removed, reducing the F/D ratio to 8.8 and transforming the refractor into a FOA-60.
