You've just managed to center a hard-to-find object in your low-magnification eyepiece's field of view. After several moments of admiration, you decide to zoom in for a closer look. But that usually means swapping out your eyepiece several times, as you increase magnification. The slightest bump or jiggle, and you may have to relocate and center the object all over again. Suppose after several swaps to zoom in, you realize the object is best-viewed at low magnification?
With Orion's new Premium Zoom Telescope Eyepiece, the problem is solved! The Premium Zoom is an elegant and convenient alternative to using multiple telescope eyepieces of differing focal lengths to achieve views of differing magnification. With the Premium Zoom, you simply adjust the focal length up or down according to your preference, without having to remove the eyepiece from the telescope focuser.
The Orion Premium Zoom Telescope Eyepiece features a focal range of 22.5mm to 7.5mm, with marked indicators for settings of 7.5mm, 12mm, 17mm and 22.5mm. The wide range of focal lengths allows you to enjoy the finer details of an object, as well as its more apparent features, while leaving the eyepiece securely seated in the focuser. The large ocular lens provides comfortable viewing with a 42 degree apparent field of view at 22.5mm, and a 66 degree field of view at 7.5mm.
The telescope eyepiece, which consists of eight lens elements in five groups, is fully multi-coated (all air-to-glass surfaces) with anti-reflection coatings for clear, crisp views. The lens edges have been blackened to prevent glare. Dual-purpose threading of the 1.25" barrel enables the eyepiece to be used with Orion filters, while also preventing glare.
The Orion Premium Zoom, made of black anodized aluminum construction, was designed with viewing comfort in mind. It features generous eye relief of 19.5mm at the 22.5mm focal length setting and 18mm at the 7.5mm focal length setting. A twist-up rubber eyeguard and rubber knurled grip ring for focal length adjustment round out the aesthetic features of this high-quality, high-performance telescope eyepiece.
Weighs 10 oz. Dust caps are included.
