Sky-Watcher 120/600 AZ3 Refractor Telescope

The Sky-Watcher 120/600 AZ3 Refractor Telescope is an impressive large-aperture instrument that provides exciting "rich field" views of star fields, clusters, and nebulae at a reasonable price. Its two-element, air-spaced, fully multi-coated achromatic objective captures significantly more light than smaller models, yet the telescope remains lightweight at under 4kg. With a short tube length of approximately 50cm, this refractor is a breeze to transport and serves as an excellent "first telescope" for beginners or a high-performance traveling companion for advanced observers. Because it features low-maintenance, enclosed optics that come fully collimated, it is remarkably quick and easy to set up for a night under the stars.

Beyond its astronomical capabilities, this telescope is a fantastic tool for terrestrial observation and photography. The "fast" f/5 focal ratio makes it an excellent fixed-aperture 600mm lens for capturing nature photographs or lunar and solar eclipses, while the eyepiece holder includes a T-mount thread for direct attachment of camera adapters. The system is supported by the AZ3 Alt-Azimuth mount and a sturdy aluminum tripod, which features slow-motion control cables on both axes for precise horizontal and vertical tracking. Whether you are using it for wide-field 2" diagonal views of the Milky Way or for long-range terrestrial spotting, the included tube mounting rings ensure easy installation, rotation, and perfect balancing for any application.

Product Features in Detail

Massive 120mm Light Gathering

With its generous 120mm objective lens, this telescope gathers significantly more light than standard 70mm or 90mm refractors. This allows for much brighter views of faint deep-sky objects like the Andromeda Galaxy or the Great Orion Nebula.

2" Diagonal Compatibility

The focuser is designed to accept 2" diagonals and eyepieces. This is a premium feature that enables truly "awesome" wide-field views, allowing you to see massive swaths of the sky at once—perfect for scanning the star clouds of the summer Milky Way.

Precision Slow-Motion Control

The AZ3 mount is equipped with two flexible slow-motion cables. These allow for micrometric adjustments in both the horizontal (azimuth) and vertical (altitude) planes, making it easy to track moving targets or center a planet at higher magnifications.

Hinged Tube Mounting Rings

The telescope includes hinged mounting rings that allow for rapid installation. More importantly, these rings can be loosened to rotate the tube, ensuring the eyepiece and finderscope are always in the most comfortable position regardless of where the telescope is pointed.

Multi-Purpose Imaging Tool

The built-in T-2 thread on the focuser drawtube turns the telescope into a powerful 600mm telephoto lens. By adding a simple T-ring for your specific camera brand, you can begin capturing high-resolution photos of nature, the moon, or terrestrial landscapes.

Low-Maintenance Refractor Design

Unlike reflecting telescopes that require regular mirror alignment (collimation), this refractor's optics are permanently aligned and enclosed. This makes it a "grab-and-go" favorite that is ready to perform the moment it is taken outside, regardless of temperature shifts or transport.
