Theย Sky-Watcher 100mm Esprit 1000EDX Triplet APO Refractor is a high-end instrument for astro-photographers seeking quality images, yet also need a telescope that can be easily transported.
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.
