A Premium Apochromatic Triplet for Astrophotography and Visual Observing
The ED127 is a premium apochromatic telescope designed for both astrophotographers and serious visual observers, built around genuine HOYA FCD1 extra-low dispersion glass in an air-spaced triplet design that minimizes chromatic aberration.
A precision front cell allows fine collimation adjustments, and the robust 2-inch two-speed rack-and-pinion focuser with locks delivers stable, precise focus for imaging sessions.
The retractable dew shield keeps the tube compact for transport, and the integrated cradle ring handle does double duty as a DSLR piggyback mount and a Vixen-style dovetail for equatorial mounts.
