Gran Turismo 81 APO with Internal Focus Design and 32mm UniGuide

The William Optics Gran Turismo 81 APO is an 81mm f/5.9 triplet refractor telescope featuring a patented internal focuser for stability and no vignetting, plus FPL-53 glass for sharp, color-free images. This apochromatic triplet refractor features a unique and patented focuser design where the mechanism is internal to the tube of the scope, making it much more stable when cameras and other accessories are attached, and virtually eliminating vignetting. Ideal for astrophotography, the GT81 uses premium FPL-53 glass to produce incredibly beautiful, false-color-free images and high contrast clarity required for deep-sky imaging, with the cutting-edge internal focus design ensuring rock-solid stability and zero image shift. Optionally available with a 32mm UniGuide finder scope and field flattener reducer, this compact refractor excels at capturing nebulae, star clusters, and planetary targets.
