Esprit ED refractor - triplet apochromat telescope from Skywatcher

These three lens element Esprit apochromats are the new top-of-the-range models in Skywatcher's stable. Skywatcher is offering quality high-end telescopes in apertures of 120mm and 150mm for astrophotographers and demanding observers.

The triplet lens consists of an Ohara-FPL 53 lens and two elements from Schott. This combination shows no detectable colour fringing and provides a high contrast image.

Flat image field

An additional built-in flat-field corrector means Esprit apos always deliver absolutely flat and sharp images. The corrector sits directly on the focuser and provides very well corrected shots even if you are using a full format chip camera.

Linear Power focuser

The 3" Linear Power focuser provides you with all the options you need for astrophotography. Its size means that even full frame camera chips are optimally illuminated. Additional adapters reduce this large opening to the standard 2" or 1.25" sizes, as required.

This new Linear Power focuser can support even heavier accessories. The drawtube runs on a sturdy stainless steel rail and additional four roller bearings. The focuser is hence just as easy to use as a Crayford focuser, but able to carry much larger loads. This focuser can also be rotated which is immensely useful for astrophotography, so you can easily find the right camera orientation for your favourite photo subjects.

The 1:11 reduction ratio always guarantees sensitive and accurate focusing to give the optimum sharpness for camera and eyepiece.
