The Altair Vixen-format dovetail bars are available in 180mm and 250mm lengths. They're narrow, light and are the prefect option for small telescopes, for example a refractor of up to about 102mm or 4" aperture.

To mount telescopes side-by-side, we recommend the Altair TMS "Small Vixen Dovetail Clamp" which is designed to bolt directly onto either end of our Vixen (or Losmandy) bars and plates with two bolts, for maximum ridigity and strength. (If you order clamps with your bars, we'll include all the stainless steel bolts you need).

A countersunk M6 hole at each end, plus a countersunk centre M6 slot, allows maximum compatibility for attachment to most telescope tube rings on the market today.

Precision CNC machined locally, and Clear silver anodized for extra resistance to tarnishing or scratching. Silver goes with anything, like our black anodised mounting equipment, creating a nice combination of colours. Who said telescopes had to look boring? Altair TMS is a precision machined modular Telescope Mounting System. Our aim is to provide a simple, safe and rigid mounting system for most types of telescope on the market, to give our customers the best possible results for astro imaging and visual observing. All components can be re-used which makes the overall cost of ownership very cost effective in the loing run. Made from the highest grade British aerospace 6068 T6 tempered and artificially aged aluminium, which has the highest strength in the 6000 series alloy range and is extremely corrosion resistant. All threads are stainless steel, and dovetail clamps are spring loaded with teflon washers.

Many different combinations are possible using the TMS. In the example below on the left hand side, a VDB-250 (250mm Vixen Dovetail Bar) is used in a side by side arrangement, being held in a lightweight VDC (Vixen Dovetail Clamp), which is in turn bolted directly to the end of a larger 350mm Losmandy Dovetail Bar (LDB). The larger telescope is an 8" Imaging Newtonian with standard tube rings. On the opposite side, a Losmandy Saddle Plate (LSP) is used to mount a 102mm refractor.

    Very good quality product for my refractor, using 2x with 250 mm vixen dovetail bar for telescopes each side. No problems perfect tolerances engineer. F.Doré
  • Author: Gerry Munn
    Top quality machined dovetail bars fit the clamps perfectly. Very tight grip like a small vice.

    The bars are easy to balance an insert/remove with plenty of mounting positions available. The corners are radiused with no sharp edges.

    There's even a small M5 hole to put a stop-sliding-screw in case you forget to tighten them up.

    I'm a retired engineer and appreciate these products are made in Britain with care and attention from good quality stock. Long may it continue.
