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).

The Plossl 4-element design is renowned for its outstanding performance. Offering a wide 52 apparent field of view, Orion Sirius Plossl telescope eyepieces provide clear, sharp images of impressively high contrast. They're ideal for all types of telescopes: reflector, refractor, and catadioptric such as Maksutov-Cassegrains and Schmidt-Cassegrains.

The Sirius Plossl optical system is fully coated with magnesium fluoride on every air-to-glass surface. Lens edges are blackened to both reduce scattering of stray light and maximize contrast.

The lens edges are mounted in black-anodized aluminum housings with 1.25" diameter barrels for durability and precision fit in 1.25" telescope focusers, or 2" focusers equipped with a step-down 1.25" eyepiece adapter. Each barrel is internally threaded to accept 1.25" Orion filters. The built-in rubber eyeguards enhance viewing by helping to block out ambient light and properly position the eye.
