Orion Lanthanum Eyepiece

The Orion Lanthanum Eyepiece features a standard 1.25-inch barrel, which is compatible with the vast majority of modern telescopes. As long as your focuser accepts 1.25-inch accessories, this will fit perfectly.

An 80-degree field of view is considered 'ultra-wide.' It creates an immersive, panoramic effect that makes you feel like you are looking through a window into space rather than a narrow tube, which is particularly helpful for tracking objects as they drift across the sky.

Yes, the 20mm eye relief is generous and specifically designed to accommodate eyeglass wearers. You should be able to see the full field of view comfortably without needing to remove your glasses.

The 9mm focal length provides a medium-to-high magnification, making it an excellent choice for observing detailed features on the Moon, planetary surfaces, and tighter deep-sky objects like globular clusters. It strikes a great balance between magnification and image brightness.

Fully multi-coated optics significantly reduce light reflection and scattering as light passes through the glass elements. This results in a brighter, higher-contrast image with better color fidelity, which is crucial when observing faint celestial details.
