Takahashi FS-60CP fluorite apochromatic doublet refractor OTA version

Takahashi FS-60CP fluorite apochromatic doublet refractor OTA version

The latest edition of a great classic, mechanically redesigned with the ultimate aim of having a compact and lightweight telescope developed for the modern era of digital astrophotography!

Takahashi FS-60CP fluorite doublet apochromatic refracting telescope OTA-only version. Diameter D=60 mm, focal length f=355 mm (F/5.9). Includes camera angle adjuster (CAA), 2" eyepiece holder and reduction to 1.25" with self-centering ring. Original rings and Vixen/GP-style dovetail available separately.

Improved mechanics to support a new high-performance gearbox

The optics consists of an apochromatic doublet with a very high-correction calcium fluorite crystal (CaF2) lens. The lens is unchanged from the FS-60CB version, however the tube is renewed to be more mechanically robust and to accommodate the new ultra-high performance 60CP FU Focal Reducer 0.65x that screws directly into the focuser body.

The supplied accessories now include a 2" eyepiece holder and also a high-precision mechanical camera rotator.

Using the dedicated focal reducer, the Takahashi FS-60CP apochromatic refractor becomes a high-performance wide-field astrograph with only 230 mm focal length and a very fast focal ratio of F/3.8 with very high correction even on the 24x36 mm full frame format! Stellar diameters remain confined to within 3 microns RMS radius. Illumination at the edge of the full-frame format reaches an excellent 80%.

The Takahashi FS-60CP apochromatic refractor is also compatible with the Takahashi Multi-Flattener 1.04x, with a resulting focal length of 370 mm and focal ratio of F/6.2.

Accessories and equipment

A high-precision CAA camera rotator is part of the instrument's standard equipment. A set of aluminium rings with an inner diameter of 95 mm (TKA11420) and a Vixen/GP type dovetail plate (TKA11423) are also available as separate accessories.

A 2" eyepiece holder and the classic system of reduction rings up to the 1.25" self-centring eyepiece holder typical of Takahashi are also part of the standard equipment.

The tube is oversized in the centre section and near the focuser (95 mm diameter) to accommodate the high-performance 60CP FU Focal Reducer.
