The Celestron 80APO ED Glass Triplet APO Design Telescope is a high-performance refractor telescope engineered for astronomy enthusiasts and astrophotographers who demand sharp, high-contrast views with minimal chromatic aberration. Featuring a triplet apochromatic optical design, this OTA (Optical Tube Assembly) uses extra-low dispersion (ED) glass in its lens system to deliver crisp, colour-accurate images of celestial objects such as planets, moons, star clusters, and deep-sky formations.
Its compact and lightweight construction makes the telescope ideal for those who value portability without sacrificing optical quality. The dual-speed focuser enables precise focusing for both visual observing and imaging applications. While accessories like eyepieces, diagonals, and mounts are sold separately, the 80APO serves as a versatile foundation for a wide range of astronomical setups.
