Telescope-Refracting Telescopes-Sky-Watcher Esprit 150 mm ED APO Triplet Refractor

What We Like About the Sky-Watcher 150mm Esprit Refractor

• The views you will get through almost 6″ of clear aperture will be amazing!
• The 150mm air-spaced ED APO Triplet optics, made of FPL-53 ED and Schott BK-7 glass, and coupled with multi-layers of a high transmission coating, yield sharp, high contrast views with no extraneous color.
• A thread-on doublet field flattener is included in the SkyWatcher Esprit 150 Refractor package, providing a flat field from edge-to-edge.
• A good focuser is imperative when imaging, and this SkyWatcher 150mm APO refractor comes with a 3.3″ linear power focuser with M74x1 threads and micro-focusing capabilities.
• The dew shield on the SkyWatcher Esprit 150 retracts, making the length 7″ shorter for storage and travel.
• A nice selection of accessories comes with this SkyWatcher 150mm APO refractor, including a 2″ dielectric diagonal with 1.25″ Adapter, a 9 x 50 erect-image finder, a Canon camera adapter, tube brings, and an aluminum case. Add a mount (the rings have a Losmandy- style dovetail bar) and a few eyepieces to this SkyWatcher 150mm APO refractor, and you’re good to go. Curious to learn more? Check out the video below!

More About Sky-Watcher Esprit ED Triplet APO Refractors

Designed with 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.

With their three-element air spaced objective lens design, made of high quality Schott BK-7 and FPL-53 ED glass, false color is completely eliminated, yielding exceptional contrast and sharpness. Knife-edge baffles in the optical tube increase contrast even further, and 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.

The SkyWatcher Esprit 150 comes with a 9 x 50 right angle finderscope, a 2″ star diagonal, a 2-element thread-on field flattener, and a camera adapter as well as a D-style dovetail and padded case.
