TS 102mm f/11 SD - Apochromat with 2.5" RAP focuser


The TS 102 mm f/11 SDP Apo offers excellent chromatic aberration correction by combining FPL53 with an additional special glass

♦ Very good correction of the chromatic aberration thanks to a 2-element APO lens with FPL53 from Ohara and an additional special glass

♦ Very good correction even in the violet color range, where brighter SD cameras give in a little

♦ The sharpness is retained even at 250-300x

♦ Adjustable lens mount

♦ Improved 2.5" toothed RAP focuser with photo thread, 2" and 1.25" adaptation

♦ Retractable dew cap for better transport and optimal protection against scattered light

♦ Deluxe finder holder for adapting finder telescopes

♦ Binocular approaches can be used without path compensation

♦ CNC pipe clamps and EQ5 level prism rail included

♦ At just 4.6kg, the ED is easily supported by mounts like the Skywatcher EQ5

TS-Optics 102mm f/11 SDP APO refractor
A refractor with a 2-element lens and a correction like a triplet apochromat is realized by the TS 102 mm f/11 SDP Apo. The lens consists of two special glasses, including FPL53 from Ohara (Japan). The apochromat not only provides good color 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 from 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 extension tube retracted. This means you can also combine binocular approaches and a 2" diagonal mirror and observe without path compensation.
