EvoStar 120EDX APO Doublet
The Sky-Watcher Evostar 120EDX combines premium ED doublet optics with a versatile 120mm aperture, 900mm focal length, and f/7.5 focal ratio for both visual astronomy and astrophotography. The Evostar EDX refractor series are designed to deliver sharp, high-contrast views for both visual astronomy and astrophotography. Their doublet optics produce dark sky backgrounds and detailed views of planets and deep-sky objects, making the EDX series a strong choice for astronomers looking for high-quality, versatile performance.
Metallic High-Transmission Coatings
The Evostar 120EDX pairs a 120mm aperture with a 900mm focal length and f/7.5 focal ratio, making it well suited for detailed imaging of the Moon, planets, star clusters, and smaller deep-sky targets such as galaxies. Its matched ED doublet optics use FPL-53 glass and Sky-Watcher’s Metallic High-Transmission Coatings™ (MHTC™) to minimize false color and produce sharp, high-contrast images. Internal baffling helps control stray light, while the aluminum optical tube keeps the telescope lighter and easier to manage.
Doublet Affordability
Choosing a doublet refractor offers several advantages, including less glass, lower weight, and easier portability. The simpler design can also help keep costs down, leaving more room in your budget for a mount, camera, or accessories while maintaining a lightweight astrophotography setup! Please note any camera, mount, tripod, and other visual accessories imaged are not included.
Everything You Need to Get Started
Evostar EDX refractors come packed in a protective, foam-lined aluminum case with key accessories included. Each telescope features a 2.8" Crayford-style focuser, tube rings, camera angle adjuster, thread-on dew shield, focuser adapter ring, spacer, 1.25"-to-2" adapter, and V-style dovetail.
