Description
Deep-sky capability and refined manual control define the GSO Dobson N 200/1200 DOB Deluxe Version, an 8-inch parabolic Newtonian reflector with a 1200 mm focal length and listed f/6 optical ratio. Its deluxe wooden rocker box uses steel roller needle azimuth bearings and adjustable CNC altitude clutches, while the 2-inch dual-speed Crayford focuser, 30 mm Erfle eyepiece, 9 mm Super Plossl, cooling fan, 8×50 finder, tripod, and accessory tray provide a substantial visual observing system.
The BK7 parabolic primary mirror uses enhanced aluminum reflectivity with quartz overcoat, while the 10:1 micro-gear focuser supports precise adjustment with 2-inch and 1.25-inch accessories. The manual rocker base requires no electronic power or alignment, and the active primary cooling fan can be used during preparation to help the mirror approach ambient conditions before higher-magnification observation.

Manual Deep-Sky and Planetary Observation
The supplied application focuses on galaxies, nebulae, star clusters, lunar terrain, and planetary surfaces, with the 200 mm aperture providing the listed deep-sky format while the f/6 focal ratio, dual-speed focuser, adjustable altitude clutch, and cooling fan support more controlled manual observation at different magnifications.
Why Choose GSO Dobson N 200/1200 DOB Deluxe Version
The Deluxe 8-inch Dobsonian is relevant when a manual telescope needs more aperture and mechanical refinement than a basic rocker box, with roller azimuth bearings, adjustable altitude clutches, 10:1 focusing, active cooling, 2-inch accessory support, 8×50 finding, and eyepieces covering wide and higher-magnification viewing.
- 200 mm aperture for the listed deep-sky configuration
- Dual-speed Crayford focuser with 10:1 adjustment
- Cooling fan, 8×50 finder, two eyepieces, tripod, and deluxe rocker base included
GSO 2-Year Limited Warranty
The supplied product information lists a 2-year limited warranty for this telescope, and the applicable US or regional warranty terms, mirror coverage, focuser coverage, cooling-fan coverage, rocker-box coverage, registration requirements, and authorized service process should be confirmed before purchase because GSO product support varies by distributor and market.
