GSO Newtonian GSN 2001 CR OTA
Aperture 200mm / Focal Length 1000mm / f/5 Optical Tube Assembly  - 94% enhanced coating

During the past couple of years - ever since prices for telescopes have considerably dropped due to production in the far east - the 200mm Newtonian with a focal length of 1000mm has become an increasingly popular choice for amateurs. We fully agree that a telescope of that aperture and focal length can be counted among the most versatile multi-purpose telescopes in existence.

The GSO Newtonian 200/1000mm is a new telescope in this range. It adds a package of extra features that are in our opinion unparalleled in this class:

-- high definition parabolical primary mirror, better than typical Chinese optics

-- thin secondary mirror spider vanes for minimized obstruction

-- larger illuminated field through use of a well-dimensioned secondary mirror. (Very important for astro-imaging and for observing with 2" eyepieces.)

--An ultra-smooth Crayford focuser for much smoother focusing motion and zero image shift.

-- Sufficient Back focus allows you to reach focus even with DSLR cameras.

-- 94% enhanced coating for a brighter image and shorter exposure times

The GSN 2001 - A True All-Purpose Telescope

This telescope not only offers excellent optical performance, but also high quality mechanics, forming a truly all-purpose telescope with nothing to be desired.

Optical Quality

This GSO Newtonian of course has a parabolic primary mirror for optimum performance. GSO has a reputation for making some of the finest mirrors in this price range. We guarantee diffraction limited performance, but in our experience the GSO telescopes are even much better than that. One particular advantage is the very smooth mirror surface that results in practically no light scatter.

Teleskop-Service guarantees a diffraction limited performance for all our GSO telescopes. Experience shows that the telescopes are even better than this usually!

We do careful tests of all shipments so that we can guarantee a constantly high level of quality.

Astro-Imaging

The GSN 2001 is not only a visual multi-talent, but also extremely well suited for astro-imaging. You can take high resolution images of the moon and the planets with a powerful Barlow lens and the Philips webcam.

But you can also take excellent images of deep sky objects. For this we recommend to use a Coma Corrector.

The focuser is not just a cheap plastic focuser and also not a rack and pinion design with plenty of image shift, but rather a smooth, zero shift Crayford focuser..
