GSO 680 Deluxe 200/1200 Dobsonian Telescope with Wooden Base

DESCRIPTION

The GSO 680 200/1200 Deluxe Dobsonian telescope is a complete and robust astronomical observing solution, combining a 200 mm BK7 parabolic mirror with a carefully designed wooden base. Its f/6 focal ratio makes it a versatile instrument, well suited for both deep-sky objects and planetary observation. The optical treatment with 94% reflectivity ensures bright, high-contrast images, while the low secondary obstruction preserves fine details. The mechanics feature an innovative system for adjusting the altitude movement tension, using two side knobs with an anti-slip surface, along with a counterweight system adjustable by sliding the tube. The new roller bearings on the azimuth axis replace traditional Teflon pads, providing smooth and precise tracking even at high magnifications. The 2" dual-speed Crayford focuser with 1:10 reduction allows accurate focusing without play or slippage, ensuring compatibility with heavy eyepieces and correctors. The package includes a fully multi-coated 8x50 finder, two eyepieces (a 30 mm 2" wide-field Erfle and a 9 mm 1.25" Plössl), and a closed optical tube offering improved protection against stray light and humidity. An excellent choice for visual astronomy enthusiasts seeking a solid, ergonomic, and efficient instrument.

When used with the MeMstar pointing assistance module (optional), this GSO 8-inch Dobsonian telescope becomes a real pleasure to operate. This accessory is available in the pointing assistance accessories category, under accessories > automation and calibration.
