80 mm ED apochromatic doublet refractor with Japanese Ohara FPL-53 glass, 600 mm focal length and f/7.5 focal ratio. The Sky-Watcher Evostar 80EDX features a 2-inch 11:1 dual-speed Crayford focuser, 2.8-inch indexed drawtube and retractable dew shield.
Designed for astrophotography and visual observation, the Sky-Watcher Evostar 80EDX uses an 80 mm ED apochromatic doublet incorporating a premium Japanese Ohara FPL-53 glass element.
Its 600 mm focal length at f/7.5 provides strong chromatic correction and makes the telescope suitable for both deep-sky imaging and lunar or planetary observation.
The 2-inch dual-speed 11:1 Crayford focuser features a 2.8-inch indexed drawtube and integrated 360° rotatable adapter.
The aluminium optical tube incorporates internal baffling, a retractable dew shield, tube rings with carrying handle and a 45 mm dovetail bar.
FPL-53 ED Apochromatic Doublet
The 80 mm objective uses an ED doublet incorporating a premium Japanese Ohara FPL-53 glass element.
This design greatly reduces chromatic aberration and provides sharp, high-contrast images.
600 mm Focal Length at f/7.5
With a 600 mm focal length and f/7.5 focal ratio, the Evostar 80EDX provides a versatile configuration for astrophotography and visual observation.
Its 80 mm aperture and moderate focal length are suitable for star fields, clusters, nebulae, lunar observation and planetary viewing.
MHTC Coatings
The air-to-glass surfaces feature Sky-Watcher Metallic High-Transmission Coatings MHTC.
Sky-Watcher states light transmission approaching 99.5%.
11:1 Dual-Speed Crayford Focuser
Focusing is provided by a 2-inch dual-speed Crayford focuser with 11:1 reduction.
The indexed 2.8-inch drawtube assists with accurately reproducing previous focus positions.
360° Rotation
A 360° rotatable adapter is integrated into the focuser.
This allows cameras and accessories to be rotated without changing the telescope's position on the mount.
Retractable Dew Shield
The dew shield retracts to reduce the overall size of the optical tube during transport and storage.
Aluminium Optical Tube
The aluminium optical tube incorporates internal baffling designed to reduce unwanted reflections and improve contrast.
The supplied tube rings incorporate a convenient carrying handle.
