Orion 8-24mm Pro Lanthanum Zoom Eyepiece

The Orion 8-24mm Pro is a zoom eyepiece that uses premium Lanthanum glass elements. This significantly reduces chromatic aberration and eliminates color fringing, resulting in true-color, sharp images. This versatile eyepiece is great for astronomical and terrestrial viewing. With a zoom eyepiece, you can get close to small details and then zoom out to see wide views. With a twist of the rubber grip housing, you can achieve a full range of magnification with focal lengths anywhere from 8mm to 24mm. The Pro Lanthanum Zoom uses a parafocal design that allows you to maintain your focus when changing magnification. This is great when you're tracking objects because it allows you to spend less time focusing.

The Orion Pro Lanthanum Zoom eyepiece is also waterproof, so you don't have to worry about a little drizzle while you're watching wildlife in the distance or observing celestial objects in the wee hours of the morning. The twist-up rubber eyeguard also blocks ambient light, keeping your eye in the optimal position to take in the entire view.

The 8-24mm Pro Lanthanum Zoom's optics comprise 8 lens elements in 6 groups, with 5 of the elements made from lanthanum glass. Eye relief is a comfortable 20mm through the zoom range. The apparent field of view ranges from 40° at the 24mm setting, to a wide 60° when set to 8mm. The 1.25" eyepiece barrel is tapered to prevent accidental slip-outs and is threaded for use with 1.25" Orion eyepiece filters.
