Description

The Takahashi FOA-60 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 F/8.8, the FOA-60 will satisfy the most demanding amateurs. It remains very light, with a weight of only 1.5 kg, and very compact thanks to its retractable dew shield.

A 1.7x extender allows the 4-lens optical formula to evolve, at F/15. This version called 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.
