GSO - 8"f/6 Dobsonian GSD 680 - 200 mm aperture - 1200 mm focal length
Successful observations from the first light on - with first class equipment.
Join the growing number of happy users of GSO quality telescopes! We are very proud of GSO´s exceptional image quality at a very affordable price. Thousands of objects are within reach of this 8" Newtonian telescope. With its highly refined Dobsonian style mount the telescope is the ideal companion for discerning beginners and for advanced observers alike!
Galaxies will reveal their spiral structure. Planetary nebulae will display splendid detail where a smaller telescope will hardly show anything.
The quality optics from GSO will at the same time offer razor sharp images even at high magnifications. Planets and the moon will be seen in great detail. The visibility of details is not limited by the telescope, but rather by the observing conditions!2" Crayford Focuser
This is one of the best focuser this manufacturer has to offer. It is far superior to most classic rack-and-pinion focusers:
New Altitude Tension and Balancing System
- no image shift when focusing
- large load capacity: Up to approx. 3kgs with a firm friction setting
- 1:10 dual speed microfocuser for far improved focusing precision
- compression rings for 2" and 1.25" accessories
On most Dobsonian telescopes the altitude bearing is a very simple design. GSO has developed an improved altitude bearing with additional functionality: A strong steel shaft bears the weight of the tube. The tube is guided and kept in position through two CNC machined surfaces. The desired tension can be freely adjusted with a large knurled knob on both sides. This is particularly helpful when changing eyepieces where the telescope is temporarily out of balance also you can adjust the balance of the tube.
The telescope can be balanced by moving it up or down a couple of
centimetres. This may be necessary when adding a second finderscope
(e.g. a Telrad) or when using very heavy eyepieces or a binoviewer. A
scale on both sides allows you to easily achieve a symmetric bearing
position. Azimuth Roller Bearing
A modern industrial roller bearing is attached in the azimuth, so you can easily move the scope. Metal plates above and below the bearing prevent the rollers from
sinking into the softer wood of the rocker box, so the movement will
remain smooth even after years of use.Delivery contents
