Our take on the Sky-Watcher Esprit 100 ED Super APO Triplet

The Sky-Watcher Esprit 100 is a premium triplet refractor telescope. These are fantastic sets that come with a great hard case, a couple of good quality eyepieces, a reducer, a guide scope and some excellent mounting hardware. This is one of the best telescope options for visual astronomy and astrophotography.

Designed with the discerning astrophotographer in mind, Sky-Watcher's top-of-the-line Esprit refractors deliver the kind of imaging performance one would expect from telescopes costing thousands of dollars more. With the Esprit's three-element, air spaced objective lens design, false colour is virtually eliminated, yielding exceptional contrast and sharpness. Each element is fully multi-coated with Sky-Watcher's proprietary Metallic High-Transmission Coatings (MHTC), producing a transmission rate that rivals any refractor on the market.

Description of the Esprit 100 ED

In addition to superb optics, all Esprits feature exclusive dual-speed, Helinear track focusers, which provide smooth, rock-solid focusing with zero image shift. Using a captain's wheel design all focusers can be rotated, giving astrophotographers flexibility when framing their image.

As is customary, Sky-Watcher supplies everything you need to get out under the stars, including a 2-element field corrector, which guarantees a flat field across the entire imaging plane. All Esprit refractors also come with an 8x50 right angle finderscope, 2-inch star diagonal, M48 camera adapter, mounting hardware, and padded case.

Esprit 150

I have purchased the Esprit 150, bigger brother, 2 years ago from AS telescope, and I could not be happier. It was a very big investment for me, you could call it dream scope. Prior to the purchase I have received advise from AS telescope about the scope and my wishes. The Telescope had to be ordered, I was kept informed of the status and its arrival time . After about 2 months the scope arrived at All-Star telescope where it was inspected prior to being shipped to me. The scope arrived in a case which was in a double lined sturdy carboard box. I am using it for what it was designed , deep sky wide field imaging
Thank you All-Star Telescope

Outstanding Clairty

Recently purchased Sky-Watcher Esprit 100ED... This telescope is amazing! It comes with a superior case and includes high quality extras. My favorite is the field flattener that is a must for astrophotograpy. The first view through this telescope was Jupiter. So sharp and vivid that I could easily see the planet's clouds in the image. Spectacular! Can't wait to start photographing when the sky finally clears.

This superior telescope is paired with a HEQ5 Pro mount, more than enough heavy duty features for Esprit 100. Also, the EQ6 PRO mount is highly recommended, just a bit more bulk for transporting to dark sky locations. The HEQ5 is my personal choice because it is a bit more portable. Together they are a great set of gear for star gazing and definitely not a disappointment.

Finally, I can't say enough about the excellent service I received from the crew at All-Star Telescope. Real professionals and a pleasure to do business with. Thanks.
