The Sky-Watcher 80mm Esprit 80EDX Triplet APO Refractor is a highly portable instrument, while still having the imaging capabilities to deliver deep-sky astro photos of stunning quality. It's especially suited for those seeking wide field images and visual observations.
The air spaced apochromatic triplet lenses use the remarkable Ohara FPL-53 ED (extra low dispersion) glass, with exceptional colour correction over the entire visible spectrum there is no chromatic aberration even on bright objects! 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 available separately to iron out the natural off-axis astigmatism and field curvature of the objective lens, leaving a fully corrected 42mm field of view.
