Description

The Takahashi FS-60CB refractor is the ultimate mobile instrument. It combines first-class optical and mechanical qualities with outstanding compactness.

It can easily be used for astronomical or terrestrial observation. Photographers will transform it into a wide field astrograph or a guiding instrument. A focal reducer (F/4.2) and a field corrector (FL-FS-60C or multi-flattener FC/FS MFL1.04X) are available as options for this purpose. A 1.7x extender (F/10) allows the refractor to be upgraded to the so-called FS-60Q version. A wide range of accessories adapts the FS-60 to your specific needs.

The FS-60CB's main advantage is its air-spaced apochromatic fluorite doublet, manufactured with the same care as all the Takahashi larger diameter telescopes. Performances will surprise many a purist. Takahashi's mechanical excellence makes the FS-60CB one of the best refractors of this diameter available on the market. Lightweight and compact, the FS-60CB will delight all observers with its versatility.

The spot-diagrams of the FS-60CB clearly show the excellent chromatic correction at the primary focus, ensured by the fluorite doublet lens, and the good performance of the diffraction task, even at more than 14 mm from the optical axis. We should also note the major role of the optional corrector in restoring the flatness of the field for wide field photographic use. It allows unrestricted use of the latest CCD cameras and digital cameras.
