Losmandy Attachment Plate - 250mm Long
The Losmandy Attachment Plate, at 250mm long, provides the specific interface needed to connect Orion Optics UK AG and CT telescopes to high-capacity Losmandy and Paramount mounts. Machined from a single block of aero-grade aluminum, this plate ensures a rigid, flexure-free connection for instruments like the 8-inch AG telescope, establishing a solid foundation for imaging.
250mm Losmandy Plate: The Recommended Fit for 8" AG Telescopes
This 250mm plate is the factory-recommended solution for securely mounting Orion Optics UK's 8" Astrograph (AG8) and other similarly sized CT telescopes onto mounts using the Losmandy D-style saddle. The length is chosen to match the telescope's aperture, providing ample support and balance range. This plate is the essential link between your Orion Optics UK optical tube and a research-grade equatorial mount.
Solid Aero-Grade Aluminum for Guidescopes and Vixen Accessories
Milled from a solid billet of aerospace-grade aluminum, this plate is more than just a mounting interface; it's an expansion platform. When used with Orion Optics UK's CNC tube rings, the plate serves as a rigid base for attaching additional equipment. You can mount guidescopes, secondary Vixen-style dovetail bars, or other accessories directly to it, creating a compact and stable imaging setup.

Which telescopes is the 250mm Losmandy plate designed for?
This 250mm plate is specifically recommended for Orion Optics UK's 8-inch aperture telescopes, such as the AG8 Astrograph and similarly sized CT Newtonians. The general rule is to match the plate length to the telescope's aperture.
Will this 250mm Losmandy plate fit my Paramount mount?
Yes. This plate is machined with a standard Losmandy D-style dovetail profile, which is compatible with both Losmandy and Software Bisque Paramount saddle plates.
How do I attach accessories like a guidescope to this Losmandy plate?
The plate is designed to be used with Orion Optics UK's CNC tube rings. It serves as a rigid base plate onto which you can bolt additional hardware, such as a smaller Vixen-style dovetail bar for a guidescope or other imaging accessories.
I have an Orion Optics UK AG8 and an HEQ5 mount. Can I use this 250mm plate?
Not directly. Mounts like the Sky-Watcher HEQ5, EQ6, and most Vixen models use the narrower Vixen V-style saddle. This is a Losmandy D-style plate. To connect them, you would need a D-to-V style saddle adapter or a different mounting plate solution.
Is this Losmandy plate made from cast or machined aluminum?
This plate is machined from a solid piece of aero-grade aluminum. This process results in a much stronger and more rigid part compared to cast aluminum, eliminating potential flexure in your imaging train.
I have an ODK telescope. Do I need to buy this 250mm Losmandy plate?
No. According to Orion Optics UK, their ODK (Optimised Dall-Kirkham) telescopes are already fitted with the correct length dovetail plate from the factory. This plate is intended for their AG and CT telescope lines.
