Esprit PRO
Skywatcher Esprit 100 ED 5-element£2,390.00 The new Sky-Watcher Professional Esprit-100ED Quintuplet 5-Element ED apochromatic refractor is designed for the most demanding astro-imagers. The compact 5-Element design includes 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, both widefield visual and widefield photographic can be combined, without the need for additional corrector lenses. The large field covers more than 5 degrees of sky. Astrophotographers will also appreciate the fast f5 focal ratio. |  | | Skywatcher Esprit 120 ED PRO Triplet£2,645.00 120mm F7 APO Triplet Refractor with Doublet Field Flattener
Skywatcher Esprit 120 Review by SkyNews Magazine:
"The Esprit 120 has a triplet objective with one element made of prized Ohara S-FPL53 glass. I compared its performance with high-end Officina Stellare and Astro-Physics 105mm and 130mm apos employing similar premium glass. Even at high magnifica- tion with a 3mm eyepiece, star images appeared just as sharp, aberration-free and colourless as the best. I was impressed.
On subzero (°C) nights once the telescope cooled down (after 30 to 45 minutes), it exhibited none of the aberration oddities I’ve seen in some test telescopes, effects created by cold temperatures pinching optics. This is evidence of the Esprit’s excellent lens cell design, the area where aspiring apos sometimes fall short."
