Please Note

Orion has made the difficult decision to close our warehouse facility in the Netherlands. With the continuing supply chain/logistics challenges and slowness in the economy we have found that it is not economically feasible to maintain operations in the UK and Europe.

We have therefore stopped taking orders on this website. We apologize for any inconvenience.

We will continue to have Orion dealers in Europe to meet the needs of Orion consumers. We will also continue to honor the 30-Day product return period as well as honoring the Orion warranty for purchases made in the UK and Europe.

Our US-based Customer Service Representatives are here to help. Contact them via email at support@telescope.com or in the United Kingdom, via phone at 0-800-041-8146 (Monday-Friday between the hours of 1300 and 2400 GMT).

With an ultra-wide 80 field of view and true-color lanthanum optics, the 20mm Orion LHD eyepiece is sure to impress you with exquisite views of the night sky.

Like all Orion LHD eyepieces, this 20mm model features an element of lanthanum glass which eliminates color-fringing and chromatic aberrations for true-color, high-contrast views of the cosmos with exceptional clarity. The luxuriously wide 80 apparent field-of-view provides an almost panoramic viewing experience you must experience first-hand to fully appreciate. Views of everything from the Moon and planets to elusive deep-sky objects are impressively immersive in the fully multi-coated 20mm LHD Ultra-Wide Eyepiece.  

All Orion LHD 80 Lanthanum Ultra-Wide Eyepieces are designed with viewing comfort in mind. All LHD eyepieces sport a large, 30mm-diameter eye lens to peer into for a relaxing experience. Each LHD eyepiece boasts a very long 20mm eye relief so you can see the entire 80-degree field comfortably. If you wear eyeglasses while stargazing, you can leave them on while using an Orion LHD eyepiece and still enjoy the full field-of-view without eye strain.

The 20mm Orion LHD 80-Degree Lanthanum Ultra-Wide Eyepiece features a tapered 2" barrel. The tapered barrel helps the eyepiece stay put in big 2" focusers and 2" diagonals if a setscrew happens to become slightly loose during use. The 2" eyepiece barrel is threaded for use with compatible 2" Orion eyepiece filters.
