TS-Optics 102mm f/7 ED-APO refractor for astrophotography and observation

Teleskop-Service's 102mm f/7 Extra-Low Dispersion ED Refractor is an easily transportable "complete telescope" for observing and astrophotography. Well-corrected optics offer a nearly colorless image thanks to the moderate aperture ratio and built-in ED glass. Use the APO refractor for astrophotography or impressive observations. The good optics, the "photo-friendly" 2.5" focuser 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

♦ Stable and precise 2.5" focuser - ball bearing drive tube - rack and pinion adjustment

♦ 2" bushing reduced to 1.25" with compression ring and photo additional thread M63x1 and M68x1 for threaded connections

♦ Robust tube construction with fixed dew cap and CNC tube rings guaranteeing the best mechanical stability

The Duplex ED lens:

The handcrafted lens is in an adjustable, temperature compensated mount. It is a dual lens with an ED element for good chromatic aberration correction. We use the best possible manufacturer's multi-coating on every glass-to-air surface for optimal contrast.

The TS 102mm f/7 ED refractor is ideal for astrophotography:

The precise focuser and bright optics make the 102mm ED Refractor a good telescope for astrophotography. To correct the field of the image, we recommend the following correctors, which are also linked in the accessories area.

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. Working distance from the corrector's M48 thread is 111 mm With With the TSFLAT2A adapter kit you get a tailor-made adaptation for your camera.

TSRED102 - 2" field correction and focal length reduction ... focal length is reduced from 714mm to 571mm. Light intensity is improved from F/7 to F/5.8. Exposure times are reduced accordingly.We recommend the reducer for sensors up to 30mm in diameter, such as those in APS-C format.The working distance from the T2 thread of the corrector is 55mm.
