TS-Optics 102mm f / 11 ED refractor with 2.5 "RAP focuser
 

The new 102 mm f / 11 ED refractor is optimized for the visual observation and photography of the sun, moon and planets.
♦ Color-pure imaging through a 2-element ED lens

♦ Adjustable lens frame

♦ Improved 2.5 "rack drive RAP focuser with photo thread, 2" and 1.25 "adaption

♦ Retractable dew cap for better transport and optimal protection against stray light

♦ Deluxe viewfinder holder for the adaptation of viewfinder telescopes

♦ Binocular approaches can be used without path compensation

♦ CNC pipe clamps and EQ5 level prism rail included

♦ With only 4.6 kg, the ED is well carried by mounts like the Skywatcher EQ5 (note the long mechanical lever)




TS-Optics 102 mm f / 11 ED doublet refractor Optical tube
This telescope is optimized for visual observation and for photography of objects within the solar system. The ED is equipped with a high-quality ED lens and improved mechanics. The result of the new development is a practically pure image and a contrast to the moon and planets, which 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:

♦ Observation of nebulae and galaxies:
With suitable 2 "accessories you can survey a field of view of 2.4 ° in the sky. Large field observations are possible. But double stars, compact nebulae and star clusters can also be observed well.

♦ Photography and observation of objects in the solar system:
The wonderful contrast and the practically pure color image of the refractor enable detailed images of the moon and planets.

♦ Sun observation and photography:
The contrast performance of the ED lens makes the refractor a good solar telescope for observing and photographing the sun in white light, calcium and in H-alpha.

♦ Binocular observation:
If you remove the tube end piece on the back, the working distance increases from 150 mm to 270 mm when the extension tube is retracted. You can also combine binocular approaches and a 2 "zenith mirror and observe them without path compensation.

♦ day observation:
With an Amiciprisma you get an upright and right-sided image, like a spotting scope. However, the image is brighter and more contrasting than with a comparable spotting scope, which costs a multiple.

The advantage of a 102 mm f / 11 ED refractor:
In direct comparison to an achromatic refractor with a similar size, the TS 102ED offers better color-true imaging with excellent contrast. 102 mm aperture collect 63% more light than a telescope with 80 mm aperture. This also makes the 102ED an exciting telescope for deep sky observation. The relaxed aperture ratio of F11 and the high-quality 2.5 "RAP focuser enable very precise focusing. Even good inexpensive eyepieces can achieve the maximum magnification range of around 250x. The 102 mm ED is an exciting alternative for all star lovers who are looking for a flexible and portable telescope for all observation areas of amateur astronomy.
