Losmandy Attachment Plate 300mm Long
The Orion Optics UK AG8 Losmandy attachment plate provides a solid 300mm long mounting platform, specifically designed to securely attach Orion Optics UK CT and AG telescopes to high-capacity Losmandy or Paramount mounts.
Machined from a single piece of aero-grade aluminum, this dovetail plate ensures a rigid, flex-free connection between your optical tube and mount head. This stability is critical for maintaining pointing accuracy and achieving sharp results during long-exposure imaging sessions.
A Solid 300mm Connection for Losmandy & Paramount Mounts
This 300mm dovetail plate is the standard interface for mounting Orion Optics UK's CT and AG series telescopes onto mounts that use the Losmandy D-style saddle. It creates a secure, full-length connection recommended for telescopes with apertures around 300mm, preventing any potential sag or vibration.
Beyond its primary mounting function, this plate can also serve as a rigid base for attaching accessories. When installed across the top of CNC tube rings, it provides a stable platform for guide scopes, secondary cameras, or other equipment.
Machined Aero-Grade Aluminum Construction
The AG8 plate is machined from a solid billet of aero-grade aluminum, not extruded. This manufacturing process results in a stronger, more dimensionally stable plate that resists flexure under heavy loads, ensuring your optical alignment remains precise throughout the night.

What size Losmandy plate do I need for my Orion Optics UK AG12 (300mm) telescope?
The 300mm Losmandy attachment plate (AG8) is the recommended choice. As a general rule, Orion Optics UK suggests the plate length should match the aperture of your telescope to provide optimal support along the tube.
Is the AG8 Losmandy plate compatible with Vixen-style mounts like the Sky-Watcher HEQ5?
Not directly. The AG8 is a Losmandy D-style plate, which is wider than a Vixen V-style rail. To connect to a Vixen-only saddle like the one on an HEQ5, you would need an additional adapter or a different Vixen-specific dovetail plate.
Why is the AG8 Losmandy plate machined from solid aluminum instead of being extruded?
Machining from a solid block of aero-grade aluminum creates a more rigid and dimensionally stable plate compared to an extruded profile. This process prevents flexure, which is critical for maintaining polar alignment and guiding accuracy during long-exposure astrophotography.
Can I use this 300mm Losmandy plate to mount a guide scope on top of my CT10 telescope?
Yes, if your CT10 is fitted with CNC tube rings. This plate can be attached across the top of the rings to provide a long, stable platform for mounting a guide scope, a secondary camera, or other accessories.
Do I need to buy this Losmandy plate for my Orion Optics UK ODK telescope?
No. Orion Optics UK ODK telescopes are supplied with the correct length Losmandy dovetail plate already fitted from the factory.
Will this AG8 Losmandy plate fit mounts from other brands like Paramount?
Yes. The AG8 plate is designed to fit any mount that uses the standard Losmandy "D-style" saddle, which includes high-end mounts from both Losmandy and Software Bisque (Paramount).
