FS-60CB OTA

FS-60CB OTA

The Takahashi FS-60CB apochromatic refractor is the itinerant telescope par excellence. It features exceptional optical and mechanichal qualities (objective with Fluorite doublet) and an incredible compact design. All Takahashi is in it.

Its great versatility will charm all the observers. It can easily be used for the visual observation, as well as astronomical or terrestrial. For the photographers, it is transformed into wide field astrograph or guiding scope. For this last function, Takahashi proposes even an optional specific parallel support, the TGM.

Features:

Apochromatic objective with Fluorite doublet

Its first quality comes from its apochromatic objective with Fluorite doublet of 60mm of aperture, as good as refractors with higher diameter. The FS-60 will astonish more than one purist. When one knows what one can obtain from an excellent short focal length optic (F=355mm, F/D 5,9) in imaging, we immediately understand all the advantage of this small compact and transportable telescope.

Exceptional mechanics

Excellent Takahashi mechanics propels the FS-60CB at the top of the refractors of this category. Its tighted rack-and-pinion focuser is designed for astrophotography and CCD imaging. A thumb screw maintains the focuser in position whatever the direction of pointing is.

Versatility and performances

Light and compact, the FS-60CB can be easily change into planetary telescope or wide field CCD imager or auxiliary instrument for guiding, and this, thanks to a vast range of accessories.
