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).

Bring your telescope to new heights - literally - with this handy Pier Extension for the Orion Sirius Pro AZ/EQ-G GoTo Mount.

Once installed, this sturdy extension raises the Sirius Pro mount head 6.3" (16 cm) for more comfortable viewing. The added height provided by the extension is especially convenient for users of refractor and Cassegrain telescopes, since their focusers and eyepiece holders are positioned at the rear of the telescope tube. With the Orion Pier Extension for Sirius Pro Mount installed, you won't have to bend in awkward positions while observing the night sky.

The 2 lb., 4.1 oz. (1.02 kg) Pier Extension is made of machined metal with a black powder coat finish. The entire extension including attachment housings measures 7-1/4" (18.4cm) long with a 3-5/8" (9.2cm) diameter to provide 6.3" (16cm) of additional height once installed. Installing the extension between the pier and mount head is easy; additional hardware included.
