    • 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).

    Cassegrain telescopes (or catadioptric telescopes) offer versatility and high magnifying power. They employ both mirrors and lenses that fold the light path, allowing a compact tube length. Orion Telescopes carries both Schmidt-Cassegrain telescopes and Maksutov-Cassegrain telescopes in a variety of sizes, all of which provide excellent image quality and all-around viewing capability. Both types of Cassegrain telescopes feature a front corrector lens that ensures sharp images. Small Maksutov-Cassegrain telescopes make great grab and go scopes, while Schmidt-Cassegrain telescopes accept a wide variety of accessories for both observing and astrophotography applications.
