Simply grip the rubberised barrel and turn it slowly while looking through the eyepiece, and pick the best power for the object you are observing.

Use the lower magnification at 24mm and zoom in until you reach the perfect view. It is fast and easy, and lets you examine any object at various magnifications without requiring you to physically change eyepieces.

The 8-24mm Zoom Eyepiece uses premium optics that are fully multi-coated for crisp, clear images. The folding eyecup lets you view with or without glasses, and the field of view (40 - 60 degrees) works well for terrestrial observations as well as for views of the Moon, planets, and deep-sky objects.
