TS ED 102mm f / 7 APO Refractor telescope with 2 "Crayford Focuser

TS Premium 102mm f7 ED Refractor Telescope with improved image through ED duplex lens.

The TS 102 mm ED refractor with a 714 mm focal length is a recommended telescope for astrophotography and for visual observation.

♦ Premium 102 mm f / 7.0 ED 2-element lens with improved color correction and good light intensity

♦ Excellent mechanical processing with CNC tube, CNC pipe clamps and temperature compensated adjustable lens mount

♦ Very stable 2 "-Crayford eyepiece with oversized ball bearings and fine 1: 10 micro adjustment

♦ Good transportability thanks to a retractable dew cap - only 615 mm transport length

♦ Very good image field correctors and reducers for astrophotography are available as an option


The 102mm F / 7 Extra-Low Dispersion ED Refractor from Telescope Service is a well-placed "all-round telescope" for observation and astrophotography. The very well-corrected optics offer a nearly colorless picture due to the moderate opening ratio and the built-in ED glass. Use the APO refractor for astrophotography or for impressive observations. The good optics, the "photofriendly" eyepiece extraction and the good workmanship guarantee joy and success and wonderful experiences under the starry sky.

The advantages of the TS 102mm f7 ED refractor:

♦ very well corrected ED optics - adjustable
♦ very transportable due to insertable dew cap (only 615 mm transport length)
♦ Stable and accurate 2 "-Crayford extraction with the possibility to screw photoadaptions
♦ 360 ° rotation

The Duplett ED lens:

The hand-made lens is in an adjustable and temperature-compensated version. It is two-lined with an ED element for a good correction of the color error. We use the best possible multi-coating of the manufacturer on every glass-air surface for optimum contrast.


The TS Linear Power 2 "-Crayford pull-out:

♦ Reinforced ball bearings - no risk of tilting

♦ Stainless steel tread for soft, soft adjustment even at maximum load

♦ 2 "plug-in sleeve with ring clamp can be unscrewed and photo adaptations can be screwed over a 54 mm female thread.


Astrophotography by the TS 102mm f7 ED
The correctors are linked in the "Accessories" section.

TSFLAT2 - 2 "Field correction without changing the focal length ... Excellent illumination - also suitable for larger sensors - a field of approx. 40 mm diameter is 100% illuminated The working distance from the M48 thread of the corrector is 111 mm.

TSRED102 - 2 "Field Correction and Focal Length Shortening ... The focal length is shortened from 714 mm to 571 mm, the light intensity increases from F / 7 to F / 5.8 The exposure times are shortened accordingly We recommend the reducer for sensors up to approx 30 mm diameter, such as the APS-C format The working distance from the T2 thread of the corrector is 55 mm.
