Individual refractor 102/1100mm - Aperture 102mm (4") - focal length 1100mm
Achromatic refractor with reduced colour abberation, 2" Crayford focuser with 1:10 transmission and retractable dewcap

A classical Fraunhofer system offers very good performance when it is designed correctly. Amateur astronomers are often surprised when they have a look through an excellent achromatic system like the TS Individual 102.

The TS Individual 102 has the following characteristica:
-- Apertue 102mm / focal length 1100mm / focal ratio f/11
-- Less false colour because of longer focal length and optimized acromatic objective
-- 2" Crayford focuser with 1:10 transmission
-- Retractable dew cap causes reduced transport length
-- Dew cap diameter: 124 mm
-- OTA length: 98cm
-- OTA weight: 5.4 kgs incl. CNC clampshells



The Individual 102's objective:
The objective has a thoroughly designed lens cell and is adjustable. It is tested for optimal centering before shipping.

-- Limiting visual magnitude: 11m8

(Diagonal mirror, eyepiece and viewfinder optional)

High-quality 2" Crayford focuser with 1:10 transmission:

The focuser is one of the most important parts of a telescope. It must not only support the accessories but also guarantee fine focus adjustment and smooth travel without radial shifting. This Crayford system fulfills these tasks and makes pinpoint focusing possible.
