The Skywatcher ESPRIT 100 ED Quintuplet 5 Element ED apochromatic refractor telescope offers premium imaging performance without compromise. This telescope is of the highest quality with optical performance rivalling or exceeding similar telescopes of even the most famous high-end telescope brands.

The Skywatcher ESPRIT-100ED Quintuplet Super Apo has been designed for the most demanding astro-imagers but is also a fine flat field telescope for visual observations. The premium, superbly-corrected optical system delivers high-contrast images full of detail with pin-point stars right up to the edge of the field and zero detectable colour fringing, even on the brightest of objects.

This teelscope offers a unique, highly portable 5-Element design using two ED elements. Most importantly, the design puts all five lenses in front of the focuser, leaving a free back focus of more than 150mm. A large variety of accessories (focus wheels etc.), both widefield visual and widefield photographic can be combined, without the need for additional corrector lenses. The large field, covering more than 5 degrees in the sky is presented in superb aberration-free quality. Astrophotographers will also appreciate the significantly fast focal ration of f/5
