A refractor with a 2-element objective and a correction like a triplet apochromat, which is realised by the TS 102 mm f/11 SDP Apo.
The objective consists of two special glass elements, including FPL53 from Ohara (Japan). The apochromat not only maintains good colour correction in the spectral range of 480-656 nm, but thanks to the relaxed aperture ratio of f/11 and the additional special glass, the correction is also very good in violet and short-wave blue light. This makes the Apo a fine telescope for observation and photography if you want to get the best performance out of a 102 mm aperture.
Binocular observation: If you remove the rear tube end piece, the working distance increases from 150 mm to 270 mm with the focuser tube retracted. This allows you to combine binocular attachments and a 2" diagonal mirror and observe without having to adjust the focus.
