Sky-Watcher Evostar 72 ED OTA Refractor

Sky-Watcher presents an exciting opportunity for those looking to embark on a serious astrophotography journey. The Evostar series offers a range of telescopes designed to meet the needs of beginners and provide exceptional performance. With features like low-dispersion (ED) glass, a short focal length, and lightweight design, the Evostar series imposes lower requirements on the mount's carrying capacity compared to the popular Newton 150/750 telescopes commonly used by astrophotography beginners. Furthermore, these telescopes are also ideal for visual observations, serving as excellent sky survey instruments due to their short focal length.

Optical System

The Evostar 72 ED is a two-element refractor that incorporates low dispersion (ED) glass lenses. With a 72mm aperture and a focal length of 420mm, this instrument achieves a high light output at f/5.8. This characteristic makes the Evostar 72 ED perfect for astrophotography, enabling shorter exposure times compared to telescopes with lower light output. For visual observations, the short focal length provides an extensive field of view, further enhanced by the telescope's high-quality optics. As a result, the Evostar proves to be an exceptional instrument for exploring the celestial wonders.

Mounting

The tube comes without an assembly but is equipped with a dovetail. Thanks to its lightweight construction, the telescope can be utilized for astrophotography purposes with a relatively light equatorial mount. For visual observations, a stable photographic tripod or a lightweight altazimuth mount will suffice.

Focuser

The telescope features a precision Crayford focuser with micro-movements, offering dual-speed control and a 2" diameter.

Terrestrial Observations

The optical design of this telescope makes it well-suited for ground-based observations as well. By employing a diagonal prism, the telescope can function as a high-quality terrestrial observation instrument, allowing shooting at the desired focal length.
