Product description

Dobsonian Telescopes from GSO are often purchased by beginners due to their simplicity and ease of use. Dobsonian telescopes are designed for visual observing. GSO Dobsonians have a better coating and high quality mirrors for maximum success and fun under the starry sky. Its cost/performance ratio is truly unbeatable.

For best possible image quality you need high quality optics as well as optimized mechanics. The GSO Dobsonian has both. The thin spider vanes improve contrast and image sharpness compared with a simpler spider with thick vanes. The 94% enhanced coating on main mirror and secondary mirror produces a brighter image. Save up to 10% light against other telescopes with same aperture.

The simple and intuitive way to use this telescope makes it much easier for beginners to spend their first joyful hours under the starry sky. Set-up is as easy as you can imagine: Just put the rocker box on the ground, insert the telescope tube and put the springs in position and you´re ready to go!

A dobsonian telescope from GSO is a perfect starter telescope. You will get a high end optic for an incredible low price. Later you can upgrade the telescope with eyepieces, filters or with cradle rings to mount it upon a equatorial mount. Than you also can start with astrophotography through your newtonian telescope.
