  • Sky-Watcher Evostar EDX 120 APO f/7.5 Doublet Telescope

    The Sky-Watcher Evostar EDX 120 APO f/7.5 Doublet Telescope combines a 120 mm aperture with a 900 mm focal length in a 6.74 kg (14.9 lb) optical tube. Its apochromatic doublet objective uses one Japanese Ohara FPL-53 ED element to control chromatic aberration; the highest practical power is 360x. The upgraded mechanical design includes a dual-speed (11:1) 2-inch Crayford focuser with an enlarged 2.8-inch indexed drawtube and a 360° rotatable adaptor.

    The 120mm f/7.5 APO Doublet with FPL-53 Glass

    The 120EDX keeps the f/7.5 matched optics of the earlier Evostar-120ED, including one Japanese Ohara FPL-53 ED glass element to control chromatic aberration. Sky-Watcher presents it as an instrument for both imaging and visual use, with the necessary accessories.

    Each air-to-glass lens surface carries Sky-Watcher's Metallic High-Transmission Coatings (MHTC), and the aluminum tube is internally baffled.

    Mechanical Upgrades: A 2.8-inch Drawtube and 11:1 Focuser

    The 120EDX adds mechanical upgrades over the Evostar-120ED, in a white and green livery. The 2-inch Crayford focuser is backlash-free and has dual-speed 11:1 fine focusing.

    The enlarged 2.8-inch indexed drawtube has a built-in 360° rotatable adaptor for turning the camera or diagonal, and the drawtube adaptor accepts a 2-inch star diagonal. The finderscope mounting shoe is compatible with all Sky-Watcher finderscopes.

    Visual Use

    The highest practical power is 360x.

    Sky-Watcher supplies the telescope without eyepiece, star diagonal and finderscope, so add a 2-inch star diagonal, a finderscope and at least one eyepiece. It includes a 2-inch to 1.25-inch adapter, allowing you to use eyepieces and accessories in both standard barrel sizes.

    Optional 0.85x Reducer/Flattener, 44 mm Image Height

    For imaging, Sky-Watcher offers an optional, optically matched 0.85x focal reducer/field flattener (code 20234), sold separately.

    With it, the image height is 44 mm.

    Tube Rings, Accessory Rail and 45 mm Dovetail

    The Evostar 120EDX optical tube assembly weighs 6.74 kg (14.9 lb) and comes ready to mount. It comes with tube rings and a 45 mm (Vixen-style) dovetail bar, so choose a mount with a Vixen-style saddle and a payload rating that covers the tube plus your accessories.

    A top accessory rail on the tube rings doubles as a carrying handle.

    Tube Length, Dew Shield and Case

    The aluminum tube measures 774 mm with the retractable dew shield retracted and 848 mm extended.

    An aluminum carrying case is supplied.

    Doublet or Triplet

    Evostar ED doublets have long been a choice of many astrophotographers for their imaging performance and affordability.

    With less glass, they are usually lighter and more convenient to handle than a triplet or other multi-element ED refractor of the same aperture. The 120EDX tube weighs 6.74 kg (14.9 lb).

  • What mount do I need for the Sky-Watcher Evostar 120EDX?

    The optical tube weighs 6.74 kg (14.9 lb) and comes with a 45 mm Vixen-style dovetail bar, so choose a mount with a Vixen-style saddle and a payload rating that covers the tube plus your camera and accessories.

    What is the highest practical power of the Evostar 120EDX?

    The highest practical power is 360x.

    What does the Ohara FPL-53 element in the Evostar 120EDX do?

    It is the ED glass element in the doublet objective, used to control chromatic aberration.

    Is there a reducer for imaging?

    Yes. Sky-Watcher offers an optional, optically matched 0.85x focal reducer/field flattener (code 20234). With it, the image height is 44 mm.

    What accessories do I need to start visual observing with the Evostar 120EDX?

    A 2-inch star diagonal, at least one eyepiece and a finderscope: Sky-Watcher supplies the telescope without them. The finder shoe takes all Sky-Watcher finderscopes, and a 2-inch to 1.25-inch adapter is included.

    Can I use 1.25-inch eyepieces with the Evostar 120EDX?

    Yes. The telescope is equipped with a 2-inch focuser, but it includes a 2-inch to 1.25-inch adapter. This allows you to use the full range of both 1.25-inch and 2-inch eyepieces and accessories.

    What does the 360° rotatable adaptor on the Evostar 120EDX's focuser do?

    It is built into the 2.8-inch drawtube and lets you turn the camera or diagonal.

    What are the main differences between the Evostar 120EDX and the older 120ED model?

    The 120EDX model features several mechanical upgrades while retaining the same f/7.5 optics. The key changes are an enlarged 2.8-inch indexed drawtube, a built-in 360° rotatable adaptor, a retractable dew shield, and a top accessory rail that also functions as a carrying handle.

    How portable is the Evostar 120EDX?

    The optical tube weighs 6.74 kg (14.9 lb) and has a retracted length of 774 mm. It comes with a durable aluminum carrying case.

    Will my Sky-Watcher finderscope fit the Evostar 120EDX?

    Yes. The telescope is equipped with a finderscope mounting shoe that is compatible with all Sky-Watcher finderscopes.

    Does the Evostar 120EDX come with a case?

    Yes, an aluminum carrying case is included with the telescope.
