The Starfield ED102 F/7 APO Doublet Telescope delivers exceptional optical performance for both deep-sky astrophotography and high-magnification visual astronomy. Featuring premium FPL53 Extra-Low Dispersion glass paired with a Lanthanum element, this refractor telescope provides virtually color-free views with remarkably fast thermal cooling times. Built with a robust 2.5-inch dual-speed rack and pinion focuser, it easily supports heavy camera gear and visual accessories for demanding observers.
Advanced Optical EngineeringPremium ED Glass Performance Defined
Designed for demanding observers and astrophotographers, the Starfield ED102 F/7 APO Doublet Telescope sets a high standard in color correction and optical design. By pairing Japanese Ohara FPL53 ED glass with a high-end Lanthanum element, this optical tube assembly rivals the chromatic performance of complex triplet telescopes while offering significantly faster cool-down times. The precision-machined 102mm objective lens features a temperature-compensated cell and fully baffled interior to eliminate stray light and maximize contrast across the entire field of view.
Equipping astrophotographers for immediate success, the Starfield ED102 APO Doublet features a heavy-duty 2.5-inch rotatable dual-speed focuser with a self-centering lock, sturdy HD CNC tube rings, a Vixen-style dovetail bar, and a retractable dew shield for seamless transportation and setup in the field.
