Description:
TS-Optics 102 mm f/11 ED Refractor with 2.5" RAP Focuser
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, we recommend the refractor especially for the following areas:
Observing 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.
Here you can find some astrophotographs made with this telescope model: Link to Astrobin
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.
