TS Optics Apochromatic Refractor AP 102/1122 ED OTA

This telescope is optimized for visual observation and photography of objects within the solar system. The ED is equipped with a high-quality ED objective and improved mechanics. The result of the new development is an image practically free of chromatic aberration and a contrast of moon and planet that sets standards in this telescope class.

The 102 f/11 ED is a portable all-round telescope:

• Watching nebulae and galaxies: With suitable 2″ accessories, you can see a field of view of 2.4° in the sky. Large field observations become possible. But also double stars, compact nebulae and star clusters can be observed well.
• Photography and observation of solar system objects: The beautiful contrast and the practically non-existing chromatic aberration of the refractor allow detailed images of the moon and planets.
• Solar observation and solar photography: The contrast performance of the ED objective makes the refractor a good solar telescope for observing and photographing the sun in white light, calcium and H-alpha.
• Binocular observation: When you remove the rear end of the tube, the working distance increases from 150 mm to 270 mm when the extension tube is retracted. You can also combine binoviewer approaches and a 2″ star diagonal and observe without path compensation.
• Daytime observation: With an Amici prism you get an upright and non-mirrored image, like through a spotting scope. The image, however, is brighter and more contrasting than with a comparable spotting scope, which costs many times more.

In direct comparison to an achromatic refractor of similar size, the TS 102ED offers better color fidelity with excellent contrast. 102 mm aperture collect 63 % more light than a telescope with 80 mm aperture. This makes the 102ED also an exciting telescope for deep sky observation. The relaxed aperture ratio of f/11 and the high-quality 2.5″ RAP focuser allow very accurate focusing. The 102-mm-ED is an exciting alternative for all star enthusiasts who are looking for a flexible and portable telescope for all observation areas of amateur astronomy.
