The Sky-Watcher Esprit 100 ED APO Refractor is a purpose-built instrument for astrophotography, but is also great for visual astronomy. The triple air spaced optical design completely eliminates color aberrations, while the elite ED glass, fully treated with Sky-Watcher's propietary high-metallic coating, yields light transmission rates rivaling any scope on the market.

Still, the Sky-Watcher designers have gone two steps further to make sure the Esprit stands out among other elite astrographs. The scope comes with a 2-element field corrector, specially designed for this instrument, that guarantees a flat field across the entire imaging plane, much better than any third party field corrector ever could.

Also, the exclusive Helinear Track focusing system, which makes innovative use of bearings within a linear track system, keeps even heavier accessories nice and square inside the focuser, achieving smooth adjustment and zero image shift.

  • Specially crafted thread-on field corrector

Sky-Watcher Esprit 100 ED APO

This is my first imaging telescope. I combined the Esprit 100 with a Celestron CGX mount, Sky-Watcher guide scope, ZWO guide camera and a Canon DSLR.
Setup has been straight forward with lots of information available on-line. I completed my first polar alignment using Sharpcap and am waiting for some clear Colorado nights to get started. Thanks to Ryan at Telescope Space for helping me put this together.

This shroud covers it all.

This shroud blocks out all of the light trespass in my area. It has two slots for the eyepiece and the finder scope. A must have item for this instrument.

Nicely emersive experience.

This lens has me looking into more 2" eyepieces from the same series. The views are amazing and Crystal clear. Literally room to stretch out the eyes.
Ring Nebula is so beautiful through this lens, truly breathtaking.

Fast, reliable, spot on customer service.

I have been in the market for an Ultralight 12" Dobsonian telescope. Ryan helped me with useful information on Explore Scientific telescope. What an amazing purchase. A high quality instrument and a dream come true for collimation. Great company, great scope.

Coming equipped with two decent eyepieces and an adapter is nice. Will upgrade to a 2" eyepiece one day, but not in the budget right now. Thanks to Ryan for help with ordering.

Easy

I'm enjoying the telescope very much. It's not too hard to assemble, although very slowly the first time.
