Introduction
The spirit of perfection, by Sky-Watcher
Designed with the discerning astronomer in mind, Sky-Watcher top-of-the-line Esprit refractors
deliver the kind of imaging performance one would expect from telescopes costing much more. With
their three-element air spaced objective lens design, false color is completely eliminated, yielding
exceptional contrast and sharpness.
The 2.7" CNC machined 1:11 rotatable dual speed linear power focuser provides a smooth, rock-solid
focusing with zero image shifts. The Esprit ED 80mm refractor comes with a 9 x 50 right angle finder
scope, 2-inch Star diagonal, EQ5 (Vixen-style) dovetail, eyepiece and padded case. Everything you
need to get out under the stars.
The 2-element thread-on 48mm field flattener guarantees excellent field flatness across the entire 33
mm imaging plane. Its oversized lenses ensure a larger and clearer aperture and also extremely
minimized halation.

NEVER USE YOUR TELESCOPE TO LOOK DIRECTLY AT
THE SUN. PERMANENT EYE DAMAGE WILL RESULT.
NEVER USE AN EYEPIECE-TYPE SOLAR FILTER.
NEVER USE YOUR TELESCOPE TO PROJECT SUNLIGHT
ONTO ANOTHER SURFACE; THE INTERNAL HEAT BUILD-
UP WILL DAMAGE THE TELESCOPE OPTICAL ELEMENTS.
USE A PROPER SOLAR FILTER FIRMLY MOUNTED ON THE
FRONT OF THE TELESCOPE FOR VIEWING THE SUN.
WHEN OBSERVING THE SUN, PLACE A DUST CAP OVER
YOUR FINDERSCOPE OR REMOVE IT TO PROTECT YOU
FROM ACCIDENTAL EXPOSURE.
NEVER LET A TELESCOPE POINTING THE SUN
UNATTENDED.
