Orion Optics UK Losmandy Attachment Plate 450mm Long

Its primary function is to securely mount Orion Optics UK CT or AG telescopes onto a Losmandy "D-style" or Paramount equatorial mount saddle. It's machined from solid aluminum to provide a rigid, flex-free connection essential for astrophotography.

As a general guideline, the dovetail plate's length should be similar to your telescope's aperture. This 450mm plate is therefore recommended for instruments with an aperture around 450mm (approximately 18 inches) to ensure stable support across the tube rings.

Not directly. This is a wide "D-style" Losmandy plate, while the EQ6-R Pro and similar mounts often use a narrower "V-style" saddle (though many now feature dual saddles). To use this plate with a Vixen-only saddle, you would need a separate V-to-D adapter.

Yes. If your main telescope is held in a set of CNC tube rings, this plate can be attached across the top of the rings. This creates a long, stable platform for mounting a separate guide scope, finder scope, or other imaging accessories.

It is machined from a single, solid piece of aero-grade aluminum. This method of construction is superior to extruded aluminum as it ensures maximum rigidity and prevents any bending or twisting under heavy loads.

No. Orion Optics UK ODK (Optimised Dall-Kirkham) telescopes are already equipped with the correct length and style of dovetail plate from the factory. This plate is intended for their CT (Classical Cassegrain) and AG (Astrograph) Newtonian telescope lines.
