82 mm ED apochromatic doublet refractor with a 530 mm focal length and f/6.45 focal ratio. The Sky-Watcher Evolux 82ED features a 2.4-inch dual-speed 11:1 rack-and-pinion focuser, retractable dew shield and compact design suited to wide-field astrophotography.
Designed for wide-field astrophotography and visual observation, the Sky-Watcher Evolux 82ED uses an 82 mm ED apochromatic doublet with a 530 mm focal length and f/6.45 focal ratio.
Its air-spaced objective incorporates an ED glass element and features Sky-Watcher MHTC multi-coatings, with stated light transmission of up to 99.5%.
The 2.4-inch dual-speed 11:1 rack-and-pinion focuser provides precise focusing particularly suited to astronomical imaging.
Compact and portable, the Evolux 82ED features a retractable dew shield, clamshell mounting ring, 45 mm dovetail bar and foam-lined aluminium carrying case.
82 mm ED Apochromatic Doublet
The objective uses an air-spaced apochromatic doublet design incorporating one extra-low-dispersion ED glass element.
This design greatly reduces chromatic aberration and provides high-contrast images with sharp stars.
530 mm Focal Length at f/6.45
With its 530 mm focal length and f/6.45 focal ratio, the Evolux 82ED is particularly suitable for wide-field astronomical imaging.
Its 82 mm aperture also provides versatile performance for visual observation.
MHTC Coatings
The optical elements feature Sky-Watcher Metallic High-Transmission Coatings MHTC.
Sky-Watcher states light transmission of up to 99.5%.
2.4-Inch Dual-Speed 11:1 Focuser
Focusing is provided by a 2.4-inch dual-speed rack-and-pinion focuser.
The 11:1 reduction provides particularly precise fine focusing for astrophotography.
Retractable Dew Shield
The dew shield retracts to reduce the overall size of the optical tube during transport and storage.
Tube length is 425 mm with the dew shield retracted and 580 mm when extended.
Compact Mounting System
The optical tube incorporates a clamshell mounting ring with a 45 mm dovetail bar.
This configuration provides straightforward installation on a compatible mount while maintaining a compact overall design.
