Orion SkyQuest XT8g GoTo Dobson Telescope - Opening 203mm f / 5.9

... innovative GoTo telescope with automatic tracking - over 42,000 objects are positioned at the push of a button


- Innovative GoTo telescope with all the advantages of a dobson but with automatic tracking and positioning of more than 42,000 objects by powerful motors.

- 203mm / 8 "opening show you the finest details of planets and the moon's surface and offer you fascinating views to distant galaxies or star clusters

- The telescope comes pre-installed with a comprehensive and illustrated German instruction manual for observation sequences from the beginning. Two bright stars in the sky suffice for calibration.

- The power supply is about 12V, the telescope needs about 2A, with a compact Powertank you can work several nights.

- The delivery is complete with 2 "Crayford extension with microcomputer, 2" 28mm DeepView wide angle eyepiece, 1,25 "Plössl eyepiece with filament cross illumination for the exact calibration of the mount, high quality illuminator, eyepiece holder, astro software and much more.

Further information:

Dobson Telescopes from Orion USA have very good selected optics and offer a very good mechanical quality, from the eyepiece pullout to the holder of the main mirror. This gives you the best possible picture for this telescope class.

With the GoTo Dobson telescopes, Orion combines the advantages of a dobson (large aperture, good transport and low cost) with the advantages of a GoTo telescope (automatic tracking and positioning). Comparable GoTo telescopes, e.g. Schmidt Cassegrains, cost almost double the price and can not offer more. Even astrophotography of the moon and planets are possible with these telescopes, through automatic tracking.

More than 42,000 objects can be approached after a short calibration. The telescoping of the telescope requires only a few minutes and you have an illuminated crosshair eyepiece, so that the alignment of the GoTo telescope is particularly good. The objects are then always positioned in the central area of ​​the high-quality 2 "overview eyepiece, so you have enough observation possibilities for a whole life, you can also visit comets by simply entering the coordinates.

Positioning at the touch of a button and simply observing - thanks to the automatic tracking, the object remains always in the eyepiece - even at the highest magnification. This allows you to also use eyepieces that have a particularly high sharpness on the optical axis and can focus fully on the target during the observation and do not have to constantly follow the object.

The high-quality 2 "Crayford extension with a 1:10 microcomputer allows for a very accurate focus, especially with the moon and the planets, and it is also the prerequisite for successful photos of these objects, with a reduction to 1.25" So you can use 2 "and 1.25" eyepieces and photo adapters.

The diffraction-limited 8 "f / 5.9 optics with forced reflectivity (94%) offers a bright, contrast-rich image with the main mirror having a central marking for an exact collimation.The mirror support consists of homegenic glass material with a particularly low expansion, within minutes The telescope is adapted to the outside temperature and you can start with the observation.

The Orion GoTo Dobsons come with optical encoders, even with manual adjustment, the astro computer does not lose the orientation. This provides you with all the functions of a normal dobson AND of a GoTo telescope with tracking. The motors are characterized by a low energy consumption (max. 2A), you can work with a compact power supply all night.
