The Sky-Watcher Evostar 100ED APO Refractor Telescope delivers extraordinary optical performance using extra-low dispersion (ED) FPL-53 glass to virtually eliminate chromatic aberration. Perfect for both high-contrast planetary viewing and serious deep-sky imaging, this 100mm refractor telescope produces razor-sharp images of lunar ridges, planetary bands, and distant nebulae. Built for dedicated amateur astronomers, the Sky-Watcher Evostar 100ED sets a benchmark for portable, high-fidelity astronomical observation.
Precision Optics UnveiledExceptional Imaging and Visual Performance for Astronomers
Experience near textbook-perfect celestial imaging with the Sky-Watcher Evostar 100ED APO Refractor Telescope. Designed around an ED doublet objective lens utilizing premium Crown glass and synthetic FPL-53 ED glass, this optical tube assembly concentrates light into a ultra-sharp central point without diffraction pattern interference. Every lens element is individually hand-polished, light-baffled, and treated with Metallic High-Transmission Coatings (MHC) to eliminate unfocused internal reflections and maximize photon transmission. The buttery-smooth 2-inch dual-speed Crayford focuser guarantees exact focal adjustment whether you are observing Jupiter's swirling cloud belts or capturing long-exposure astrophotography targets. Complete with mounting tube rings, a 2-inch dielectric diagonal, an 8x50 RACI finderscope, two eyepieces, and a protective foam-lined aluminum carrying case, the Sky-Watcher Evostar 100ED telescope offers a complete solution for lifetime celestial exploration.
