Product Details

SharpStar has been crafting refractors for leading astronomy vendors across the globe for years. Now, they're bringing their own premium apochromatic refractors to the market under the SharpStar brand, which is rapidly gaining recognition for precision and performance.

The SharpStar 94EDPH, the third in this acclaimed series, boasts a 94mm air-spaced triplet objective with two ED glass elements, promising excellent color correction, high contrast, and superior image sharpness. Its compact size (468mm length with the dew shield retracted) and lightweight design (9.4 lbs) make it perfect for field use and travel. With a focal length of 517mm, it offers a wide 4.0 degree X 2.6 degree field when used with a full-frame camera.

This telescope also excels at visual observation thanks to its fast f/5.5 focal ratio. For those seeking advanced capabilities, an optional dedicated 2.5" f/4.4 reducer/flattener is available separately.

Priced exceptionally well for its performance, the SharpStar 94EDPH's value rivals telescopes costing three or four times as much. This value is even more prominent when used with smaller 1" and 4/3" sensor astronomy cameras. Cameras with larger APS-C and full-frame sensors may display minor aberrations at the field edge, particularly when using the focal reducer.

The SharpStar 94EDPH's top-notch optics are complemented by its mechanical quality. Its red CNC trim, white gloss tube, and carrying handle lend it a unique, eye-catching aesthetic. The telescope features a premium 3” dual-speed 10:1 rack-and-pinion focuser with 58mm of travel, comfortably accommodating most full-frame astronomy cameras. With a 1.25”-2” adapter for smaller accessories and a fitted hard case included, it's a complete package.

Alan Dyer, reviewing the 76mm cousin, the triplet SharpStar 76EDPH, says, "This is color correction that ranks with the best in the world of apos." We believe the SharpStar 94EDPH lives up to the same standards, and at a very reasonable price for its performance.
