Product description
TS CF-APO 80/480 mm FPL55 Triplet Apochromat

The 80 mm apo is pure in colour and bright in light and is equally suitable for visual observation and astrophotography. Thanks to the FPL55 APO element (comparable to FPL53) the image is first-class and in practice cannot be distinguished from the world-famous LZOS lenses from Russia.

The APO is very compact and is well supported by small mounts from EQ3 class. It is ideal for mobile use. The extra long prism rail makes it possible to use heavy cameras and still keep the telescope balanced on the mount or phototripod.

The objective of the 80 mm apo:
The triplet lens with 80 mm aperture and 480 mm focal length fulfils the criteria of a full apo. Even at magnifications of 300x, the image is free of annoying chromatic aberrations. Even bright stars are shown on astrophotos without disturbing blue fringes.

The APO element consists of FPL55. A further special glass supports chromatic correction. The air-spaced triplet objective is fully adjustable. Each optical glass-air surface is multi-coated. The objective is in a temperature compensated, adjustable cell.

The photographic 2.5" rack&pinion focuser:
The 2.5" CNC focuser is optimized for photography and can handle a load of up to 6 kg. The adjustment of the draw tube is done by gear drive. We also offer motorized focusing for the focuser. An M63x1 internal thread is available for screwed adaptations.

Astrophotography with the APO
To achieve the optimal imaging in the field, a corrector is needed. The corrector is screwed directly to the M63 thread of the apo. We recommend two correctors, both are suitable for cameras up to full format. The working distance from the M48 thread to the sensor is 55mm.

TSCFRED80 - 0.8x corrector
  • The corrector is specially calculated for this APO. It reduces the focal length to 384mm and improves the focal ratio to f/4.8.

TSFLAT25koll - 1.0x corrector
  • The corrector provides maximum illumination. It does not change the focal length and focal ratio. The working distance from the M48 thread is variable and can be fixed at 55mm by simply setting 26.2mm on the corrector.
