Why we love the Sky-Watcher EvoStar 100ED APO Refractor Telescope OTA (S11120)

We love high quality refractors. These SkyWatcher doublets give crisp views with no distortion or false color. These are fantastic grab-and-go astrographs. If you're looking for a light, portable imaging rig, the Evostar should be on your short list.

Product Description

Sky-Watcher's Evostar apochromatic doublet refractors are the perfect blend of superior extra-low dispersion glass and affordability. The Evostar refractor lens assembly utilizes a proprietary combination of matched lenses, delivering tack-sharp stars with charcoal-black, contrast-rich skies. All ED glass elements are fluorite-based and feature our proprietary Metallic High-Transmission Coatings (MHTC), virtually eliminating all false color while triple-baffles prevent stray light from affecting your photography. Like the optics, the tube is beautifully crafted using aluminum and finished with a black diamond metal-flake finish.

Using a doublet refractor instead of a triplet has some advantages: less glass means less weight, less weight means a less expensive telescope, so you can dedicate more money for your camera or laptop while benefiting from a lightweight astrophotography rig.

The Evostar 100ED comes in a foam-lined aluminum case fully loaded with accessories, including: 2-inch Crayford-style focuser, 2-inch dielectric diagonal, two 1.25-inch eyepieces (5mm and 25mm), an 8x50 right-angle finderscope, tube rings, and a V-style dovetail.

First impressions - Excellent scope, finder scope did not work for me, eps ok

First impressions
- Excellent scope for visual work, only a few observations so far. I think this scope will be a much better balance of portability vs aperture vs my 8" dob. I bought a cheap tripod elsewhere, which was a mistake. Explore Scientific Twilight I tripod is on the way, hopefully that will work much better.
-Finder scope did not work for me. I was not able to calibrate it, may have been a build quality problem. Red dot finder on the way.
-Eyepieces are ok. 2" 38mm and 1.25" 15mm eyepieces have arrived to fill in gaps around 25 mm and 5 mm, will try these out once the proper tripod arrives.
