The Sky-Watcher 80mm Esprit 80ED Triplet APO Refractor incorporates an air spaced 100mm Apochromatic Triplet lens system. made from FPL-53 extra low dispersion glass with knife edge baffles reduce internal reflections and increase contrast, helping to bring out faint structure in deep sky objects.

A 2-element field flattener is included to iron out the natural off-axis astigmatism and field curvature of the objective lens, leaving a fully corrected 42mm field of view.

The Sky-Watcher exclusive Helinear Track 11:1 dual speed focuser is rock solid with zero image shift and a 3″ barrel to avoid vignetting. Designed with photography in mind, it sits on two tracks above and below the barrel to prevent flexure with a heavy camera attached, and is fully rotatable to perfectly frame a target on the sensor.
