Sky-Watcher Evostar 150EDX OTA Telescope

The Sky-Watcher Evostar 150EDX OTA is a premium apochromatic refractor engineered for serious observers and advanced astrophotographers who demand exceptional optical performance, build quality, and precision. Featuring a large 150mm objective lens and an impressive 1200mm focal length (f/8), the Evostar 150EDX delivers outstanding resolution, high contrast, and superior colour correction—making it a powerhouse for planetary, lunar, and deep-sky imaging.

At the heart of the system is a fully multi-coated ED objective utilizing MHTC (Metallic High-Transmission Coatings), ensuring excellent light throughput and minimized chromatic aberration. The generously sized 3" indexed Rack & Pinion focuser, CNC-machined for maximum stability and smoothness, offers dual-speed 11:1 precision control. Combined with a 360° rotatable adaptor, the focuser provides flawless framing and fine-tuning for heavy imaging payloads.

The telescope body is constructed from high-grade aluminium with internal baffling to reduce stray light and maximize contrast. The retractable dew shield enhances portability while protecting the optics in challenging environments. The OTA includes anodised aluminium tube rings with a top accessory rail/carry handle, a 75mm dovetail mounting bar, and a finderscope shoe compatible with all Sky-Watcher finderscopes.

Designed to support up to 450x practical magnification, the Evostar 150EDX excels in high-power visual observation while remaining fully capable for demanding astrophotography sessions. The package is completed by a durable aluminium carrying case, ensuring safe transport and storage of this precision instrument.
