Sky-Watcher HyperFlex-7E2: the wider zoom range for long focal lengths
The HyperFlex-7E2 covers the zoom ranges from 9 to 27 mm exactly, the ones that are most commonly used on a Maksutov, Schmidt-Cassegrain or long refractor. Locate the object at 27 mm, zoom in to 9 mm: infinitely, and thanks to the homophocal design, virtually no secondary focusing is required.
The optics with seven lenses in four groups and multiple coatings keeps the image clear and contrasty across the entire range. With 18 mm eye relief and an adjustable eye shield, even a wearers with glasses can look relaxed.
Features
- Stepless zoom range 9 to 27 mm
- Parfocal: barely needing to refocus while zooming
- 18 mm eye relief with adjustable eye shell
- 1.25 inch vatting met filterdraad
Compatibility
Fits any 1.25-inch focuser. The longer zoom range makes it the logical choice for Maksutovs, SCTs, and refractors with long focal lengths; for short, fast tubes, the HyperFlex-7E (7.2 to 21.5 mm) is more suitable.
