The Tecnosky 102/1100mm refractor offers a very good image and high contrast on moon and planets
♦ High-quality 2-element objective - glasses from Ohara (Japan)
♦ Significantly less chromatic aberration than with f/9 or f/10 refractors according to Fraunhofer
♦ Retractable dewcap for better transport and optimal protection against dew and stray light
♦ 2" Crayford focuser with 1:10 dual speed and receptacle for finder shoe
♦ Eyepiece side connections 1.25" and 2" - the refractor can also be equipped with 2" accessories
♦ The refractor is well supported by mounts of the EQ3 and EQ5 class
♦ CNC tube rings and Vixen / EQ5 style dovetail are are included in the scope of delivery
Tecnosky has given the classical achromat a modern design which fully exploits the optical possibilities of a quality lens. The result is powerful telescope for many fields of application:
♦ Observation of moon and planets with very good resolution and contrast.
♦ Photography of objects of our solar system.
♦ With suitable solar filters, the TS 102 mm f/11 refractor is a very fine solar telescope.
♦ Great telescope for deep-sky observation. You can also use 2" accessories. With the 2" eyepiece, the refractor turns into a wide-field telescope with 2.3° field of view of the sky, that is almost 5 times as large as the full moon.
The lenses come from Ohara (Japan) and the multicoated objective is built into a high-quality, temperature-compensated cell. Due to optics and mechanics, this refractor stands above simple mass products and is a true alternative to many ED refractors.
Besides the 2" Crayford focuser, the retractable dewcap is an important feature. With this, the refractor becomes more transportable and shorter than a 102 mm f/10 refractor with fixed dewcap. When the fixed dewcap is extended, it offers optimum protection against stray light and dew.
