The Sky-Watcher Esprit 80 is a fast f/5 triplet apochromatic refractor that is perfect for capturing wide field astronomy images. 

Designed wtih the discerning astrophotographer in mind, Sky-Watcher USA's top-of-the-line Esprit refractors deliver the kind of imaging performance one would expect from telescopes costing thousands of dollars more. Combined with a DSLR having a typical APS-C size sensor, this 80 mm telescope will offer up a photographic field more than three degrees wide by two degrees high. This is ideal for imaging popular large objects such as the Andromeda galaxy or Veil nebula.

With their three-element air spaced objective lens design, false color is completely eliminated, yielding exceptional contrast and sharpness. The included 2-element field corrector guarantees a flat field across the entire imaging plane. The Sky-Watcher exclusive Helinear Track focusing system provides a smooth, rock-solid focuser with zero image shift.

All Sky-Watcher USA Esprit refractors come with a 9 x 50 right angle finderscope, 2-inch Star diagonal, 2-element field flattener, camera adapter and padded case. The 80mm Esprit includes a Vixen style dovetail. Everything you need to get out under the stars.
