Sky-Watcher Esprit 80mm ED Triplet APO Refractor

The Sky-Watcher Esprit 80mm ED Triplet Apochromatic Refractor Optical Tube Assembly is geared towards serious astrophotographers who want absolutely no compromise in the clarity of their images and exposures while being reasonably priced for a telescope of its quality. The clarity and excellent light transmission and virtually non existent chromatic aberration or false color of the Esprit 80ED is mainly credited to the apochromatic three element design, ED glass and Sky-Watcher's Metallic High Transmission Coatings (MHTC for short).

The Sky-Watcher Esprit 80ED comes with a dual speed Rack and Pinion Helinear track focuser which helps faciliate smooth and accurate focusing with no image shift, a major crucial factor in high quality exposures and a flawless visual session. The focuser can be rotated as well to correspond with how the imager is taking their exposure frames.

Other included items are a 2 element field corrector, 8x50 right angle finderscope, 2" diagonal, M48 camera adapter, mounting hardware and padded case.
