ED Triplet APO Refractor was designed by Sky-Watcher with astro-imagers in mind!

The air-spaced ED APO optics are fully multi-coated for extra clarity, contrast, and protection. Designed for the most demanding Astrophotographer, but also delivering exceptional visual observing. The two-element feld flattener, which comes standard with the Sky-Watcher Esprit, will ensure pin point stars across the entire focal plane. This system produces a full frame imaging circle, and you have plenty of back focus for additional imaging accessories.
The Helinear Track Focusing System, a Sky-Watcher exclusive, is a rock-solid 3” rack & pinion focuser that will perform smoothly, without any image shift. Capable of holding 10kg. The micro focuser allows you to make course and fine adjustments to the focus.

Included with every ESPRIT refractor.
