Sky-Watcher Evostar 120EDX Apochromatic Refractor Telescope

The Sky-Watcher Evostar 120EDX is a high-performance apochromatic refractor designed for astronomers seeking premium optical quality in a versatile and reliable telescope platform. With its 120mm aperture, 900mm focal length, and f/7.5 focal ratio, it provides an excellent balance between light-gathering capability, image scale, and portability.

The optical system uses a high-quality ED doublet objective featuring low-dispersion glass to reduce chromatic aberration and improve colour correction. This allows the telescope to deliver crisp, high-contrast images with accurate colour rendition, particularly when observing bright targets such as the Moon, planets, and double stars. The improved optical correction also benefits astrophotography by producing cleaner star profiles and reducing unwanted colour fringing around bright objects.

The 120mm aperture provides a significant increase in light-gathering capability compared with smaller refractors, revealing more detail in a wide range of astronomical targets. The telescope is particularly well suited to detailed lunar and planetary observation, where the combination of aperture and 900mm focal length provides excellent resolution and useful magnification. It is also capable of delivering impressive views of brighter deep-sky objects including nebulae, galaxies, and star clusters.

With its 900mm focal length and f/7.5 focal ratio, the Evostar 120EDX offers a highly versatile optical configuration. The longer focal length provides a useful image scale for smaller deep-sky objects and high-resolution imaging, while the moderate focal ratio keeps exposure times manageable for astrophotography. This makes it an excellent choice for imagers looking for a refractor that can handle a broad range of celestial targets.

For astrophotographers, the Evostar 120EDX provides a strong imaging platform thanks to its well-corrected ED optics and imaging-focused mechanical design. The 360° camera angle adjuster allows convenient rotation of the camera orientation for accurate framing, while the precision dual-speed focuser enables fine focus adjustments needed for sharp astronomical images.

The telescope features a robust 2.8″ dual-speed focuser with fine adjustment capability, providing smooth and accurate focusing for both visual observing and camera setups. The integrated retractable dew shield helps protect the objective from stray light and moisture while allowing the telescope to remain compact during transport and storage.

A rigid tube assembly with CNC-machined tube rings, integrated carrying handle/accessory rail, and supplied dovetail mounting bar provides a stable and practical setup for use on compatible equatorial mounts. The included aluminium carry case also makes the Evostar 120EDX suitable for astronomers who require a premium refractor that can be transported safely between observing locations.

Combining excellent ED optical performance, a versatile focal length, and refined mechanical features, the Sky-Watcher Evostar 120EDX is a high-quality refractor designed for serious amateur astronomers who want a telescope capable of delivering outstanding results for both visual astronomy and astrophotography.
