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).

Imagine a telescope so small you can tuck it into a daypack or store it on a bookshelf, yet so powerful that it has the magnification and light-gathering capability of traditional telescopes five times its size . . . Imagine a telescope equally at home looking an eagle in the eye or revealing the cloud bands of Jupiter . . . Imagine a telescope made the old-fashioned way, of enameled aluminum and precision optical glass, instead of plastic. And imagine that these telescopes are incredibly competitively priced. As you can imagine, we've got it. The Orion Apex 102mm Maksutov-Cassegrain Telescope, only from Orion.

One look at it and you immediately appreciate its abbreviated simplicity and quality details. But the proof of any great telescope is in the viewing. And one look through our Apex 102mm Maksutov-Cassegrain Telescope will prove that it's as long on optical excellence as it is short in profile. A serious telescope only incredibly portable.

Big Aperture Maksutov-Cassegrain Optics
The secret is in the light-folding Maksutov-Cassegrain design. It permits large-diameter optics, 102mm, to be housed in an unusually compact, wonderfully portable tube. As a spotting scope, the Apex 102mm gathers more light than typical field telescopes (often costing several times more), serving up brighter, more highly resolved images even in the dimmest of lighting conditions. Multi-coatings applied to the curved front lens guarantee the highest possible light transmission. For astronomy, the Orion Apex 102mm Maksutov-Cassegrain Telescope exhibits all the performance of classic long-tube 102mm refractors, and easily outperforms smaller refractors on views of the planets and Moon as well as on faint nebulas and star clusters. Its long focal length allows high-power study of Jupiter's cloud belts and Red Spot, and Saturn's rings, and provides long reach for capturing distant terrestrial targets. What's more, Apex telescopes accept standard 1.25" telescope eyepieces for nearly unlimited magnification options.

Speaking of accessories, the Apex 102mm comes with a multi-coated 25mm Sirius Plossl telescope eyepiece (1.25") and a 45° diagonal that provides a correctly-oriented field of view. As does the correct-image finder scope (6x26 on Apex 102), which makes locating objects a cinch. The finder scope is held in a quick-release dovetail bracket for easy assembly and disassembly. And here's something special: we also include a rugged, fully padded carrying case to protect your telescope. It's got hand and shoulder straps and ample pockets for accessories.

The telescope easily pops on and off a telescope mount or camera tripod with the built-in 1/4"-20 adapter plate. And it doubles as a high-power telephoto lens for photography, too. Just mount a 35mm camera body (with optional T-ring) to the T-threads on the telescope eyepiece holder and you're all set!

Imagine, a telescope that's this versatile, this powerful, this portable. And on top of all that, this competitively priced! It's here, in the Orion Apex 102mm Maksutov-Cassegrain Telescope. Take a look!
