Sky-Watcher Professional ESPRIT 3-Element ED apochromatic refractors are instruments of the highest quality with optical performance rivalling or exceeding similar telescopes of even the most famous high-end telescope brands. The ESPRIT Super Apo Triplets are designed for the most demanding astro-imagers, for use with the optional M48 field flattener, but are also fine telescopes for visual observations. The premium, superbly-corrected optical systems deliver high-contrast images full of detail and zero detectable colour fringing, even on the brightest of objects.
