Description
Sky-Watcher 8–24mm Zoom Eyepiece 1.25"
The Sky-Watcher 8–24mm Zoom Eyepiece is a versatile telescope eyepiece designed for observers who want a wide range of magnifications without carrying or changing multiple eyepieces. With its continuous 8–24mm focal-length range, you can smoothly adjust the magnification simply by rotating the zoom mechanism.
At 24mm, the eyepiece provides a wider field of view that is useful for locating celestial objects and observing larger targets. Zooming toward 8mm increases the magnification, making it suitable for closer views of the Moon, planets, double stars, and other smaller astronomical targets.
The apparent field of view ranges from approximately 40° at 24mm to 60° at 8mm. The eyepiece also offers approximately 15–18mm of eye relief, providing comfortable viewing during longer observing sessions.
Convenient Zoom Design
One of the main advantages of this eyepiece is its versatility. Instead of switching between several fixed-focal-length eyepieces, you can adjust the focal length continuously from 24mm down to 8mm. This makes it particularly convenient when observing conditions change or when you want to find the optimum magnification for a particular target.
The fold-down rubber eyecup provides comfortable positioning for the eye and can be folded down when observing with eyeglasses.
