Altair Premium Positive-Lock Diagonal - Dielectric 2" Pushfit
The Altair 2" premium diagonal with positive-lock system grips 2" accessories tightly with a small rotation of the top knurled ring, keeping them precisely centred.
The CNC machined chassis will hold extra heavy accessories without flexing, and the mirror features a premium 99% reflective dielectric-coating.
Ideal for refractors and large eyepieces or binoviewers, the positive-lock has a very light action and only needs a small 20 degree rotation, letting you quickly replace accessories. There's no need to apply excessive force on thumbscrews or normal twist-lock mechanisms to insert accessories. Once you've tried it, you won't want to use any other diagonal again, it's that easy.
- Includes a 2" to 1.25" adapter with compression ring for smaller eyepieces.
- The 2" Pushfit barrel is precision machined and is threaded for use with standard 2" astro filters (M48x0.75mm thread).
- Blackened interior for high contrast observation of bright objects.
A scratch resistant chemically stable dielectric mirror coating enables more frequent cleaning than softer aluminium-coated mirrors.
- Super-hard black anodising for extra durability.
- Includes dust caps for both ends, and a foam filled box.
