Description
Compact long-focus visual astronomy starts with the GSO Dobson N 152/1200 DOB Telescope, a 152 mm parabolic Newtonian reflector with a 1200 mm focal length and listed f/8 optical ratio. Its wooden rocker box, powder-coated steel tube, 2-inch Crayford focuser, 6×30 finder, 25 mm Plossl eyepiece, collimation cap, spring-tension components, and accessory tray create a practical manual Dobsonian system for lunar and planetary observation.
The BK7 plate-glass primary uses high-reflectivity aluminum and silicon dioxide protective coating, while the 2-inch Crayford focuser provides a wider accessory interface with a 1.25-inch reducer profile. The manual rocker base requires no batteries or electronic alignment, and the supplied spring-tension and collimation components support setup and adjustment before observation without introducing motorized tracking or GoTo controls.
