Sharpstar, renowned for crafting refractors for esteemed global astronomy vendors over the years, now offers their own line of premium apochromatic refractors at remarkably affordable prices. The Sharpstar 94EDPH marks the third installment in their series of instruments under the Sharpstar brand, swiftly garnering recognition for precision instruments tailored for both visual observation and astrophotography.
Featuring a 94mm air-spaced triplet objective with dual ED glass elements, this scope ensures outstanding color correction, contrast, and image sharpness. Sporting a focal ratio of f/5.5, it boasts a compact length of 468mm with its dew shield retracted and a weight of 9.4 lbs, making it ideal for field expeditions and travel. With a focal length of 517mm, the 94EDPH delivers an expansive 4.0-degree by 2.6-degree field with a full-frame camera, doubling as an exceptional fast-focal-ratio telescope for visual observation.
An optional dedicated 2.5" f/4.4 reducer/flattener is available separately for enhanced versatility.
Despite its modest price, this swift apochromatic telescope offers remarkable value, rivaling telescopes priced significantly higher. Its prowess is particularly notable when paired with astronomy cameras featuring smaller 1" and 4/3" sensors, although cameras with larger APS-C and full-frame sensors may exhibit minor aberrations at the field's edge, especially when employing the focal reducer.
Beyond its superb optics, the 94EDPH excels in mechanical quality. Adorned with striking red CNC trim and a carrying handle, coupled with a sleek white gloss tube, this scope exudes a distinct and appealing aesthetic. Furthermore, it boasts a premium 3” dual-speed 10:1 rack-and-pinion focuser with 58mm of travel, accommodating most full-frame astronomy cameras with ease. Equipped with a 1.25”-2” adapter for compatibility with smaller accessories and packaged in a fitted hard case, this refractor epitomizes excellence in both form and function.
