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).

Optimize your DSLR astrophotography setup and take full advantage of full-frame sensors with this handy adapter. The Superwide 2" Prime Focus Adapter provides the widest possible clear aperture to minimize vignetting -- darkening around the edges of the image sensor -- in astrophoto exposures, even when using cameras with large, full frame sensors. Nearly 10mm wider than standard T-adapters and T-rings, the Orion Superwide 2" Prime Focus Adapter boasts a clear aperture of 47.5mm for great DSLR imaging performance.

Consisting of a 2" T-adapter with an integrated Canon EOS bayonet, this useful Prime Focus Adapter allows secure attachment of any Canon EOS DSLR camera to a 2" telescope focuser. Unlike standard T-adapters that utilize a 42mm T-thread and often have an even narrower clear aperture, the Superwide 2" Prime Focus Adapter doesn't restrict the attached camera's field of view, meaning APS-C and full-frame cameras can be used to their full potential without suffering from vignetting. Its unique tapered barrel provides an extra-secure connection to keep the adapter and attached camera from detaching from a telescope should the focuser collar thumbscrews become loose.

Made of machined, black anodized aluminum, the Superwide 2" Prime Focus Adapter features internal glare threads and a flat black finish to help reduce reflections for excellent image contrast. Adds only 10mm of optical length to astrophotography setups when installed, and weighs just 2.2 ounces. Threaded for use with 2" Orion filters.
