Altair Ultra Light 100mm Guide Scope Rings - Red

Product Description

The Altair TMS 100mm diameter Guide Scope Rings in red have a unique lightweight design, which results in a far lighter guide scope ring system, while still having high strength and rigidity. Fiinished to an excellent high standard to complement any guiding setup.

Excellent Build Quality
Durable all stainless steel M8 threads - that means they will not corrode, unlike cheaper makes which use low grade blackened steel threads and screws, which eventually go brown with rust. Instead of cheap plastic knobs which are hard to grip, Altair the TMS system comes with individually machined knobs which are permanently bonded to the stainless steel threads, terminating in a special no-scratch end cap. This avoids damage to your telescope tube whilst maintaining a rigid connection for auto-guiding or even imaging with a heavy camera. Not only do the plastic end caps give a more forgiving contact with your optical tube, they are better than soft rubber or vinyl end caps, which cause movement, and eventually split.

Optical tube fitment sizes
The red 100mm rings allow the use of guide scopes with an outer diamter of around 45mm to 80mm without modification . You can accommodate wider diameter optical tubes by trimming the rear portion of the plastic end caps with a sharp craft knife. For example, if you trim 5mm from the plastic end caps, you can mount a 90mm diameter optical tube. The rings themselves have an internal diameter of 100mm.

Direct easy mounting
The Altair Guide Scope Rings are fitted via two M6 bolts on each ring, to stop them twisting like other makes. All Altair TMS Losmandy plates and Vixen bars have this two-hole pattern, and you can adjust the separation of the rings by choosing different holes along the length of the plate. The rings have flattened bases, for good contact with the bar or plate surface.

Made in the UK
Altair guidescope rings are made in the UK at our local machine shop on HAAS CNC milling machines, which means we have complete control over quality and design. Each part is hand polished before anodising to remove burs and give a smooth finish. The quality level and material means a slightly higher price than budget rings. Recommended for those who want the best.

Bolts Included
4x M6 stainless steel bolts you need to attach them to your plate or bar
