62 mm ED apochromatic doublet refractor with a 400 mm focal length and f/6.45 focal ratio. The Sky-Watcher Evolux 62ED features a 2.4-inch dual-speed 11:1 rack-and-pinion focuser, retractable dew shield and compact design optimised for wide-field astrophotography.
Designed for wide-field astrophotography and visual observation, the Sky-Watcher Evolux 62ED uses a 62 mm ED apochromatic doublet with a 400 mm focal length and f/6.45 focal ratio.
Its 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 incorporates an indexed drawtube for precise focusing.
Compact and portable, the Evolux 62ED features a retractable dew shield, clamshell mounting ring with 45 mm dovetail bar and is supplied in a foam-lined aluminium carrying case.
62 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 sharp stars and high-contrast images.
400 mm Focal Length at f/6.45
With its 400 mm focal length and f/6.45 focal ratio, the Evolux 62ED is particularly suitable for wide-field imaging.
Its compact dimensions also make it highly portable for travelling and mobile observing or imaging.
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 precise fine focusing, particularly useful for astrophotography.
The indexed drawtube assists with reproducing previous focus positions.
2-Inch Visual Adapter
A 2-inch visual adapter with compression ring is supplied.
This secures compatible accessories without tightening a screw directly against their body.
Retractable Dew Shield
The dew shield retracts to reduce the overall size of the optical tube for transport and storage.
Tube length is reduced from 370 mm with the dew shield extended to 295 mm when retracted.
Compact Mounting System
The optical tube incorporates a clamshell mounting ring with a 45 mm dovetail bar.
Two fitted finderscope shoes are also supplied.
