Condition:

This is a TS-Optics 102mm ED refractor OTA in pristine condition. The body is clean of any scratches or marks and the optics are whistle-clean as well.  This is just the OTA that you see in the photos, with rings, and that's it!  

Includes an Orion padded long-tube soft case.  We do not have the packing boxes for this, so this is available for in-store pickup only.  

The new 102 mm f11 ED refractor is optimized for the visual observation and photography of sun, moon and planets.

• Image free from chromatic aberration through 2-element ED lens with additional special glass, comparable to an FPL53 doublet with f/8
  
•  Adjustable lens mount
•  Improved 2.5" gear drive RAP focuser with photo thread, 2" and 1.25" adaption
•  Retractable dew shield for better transport and optimum protection against stray light
•  Deluxe finder holder for the adaptation of finder scopes
•  Binocular approaches can be used without path compensation
•  CNC tube rings and EQ5 style dovetail bar included in scope of delivery
•  With only 4.6 kg the ED is well supported by mounts like the Skywatcher EQ5.

Description:

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

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 binoviewers 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.
