About the Altair Telescope Mounting System: Many different combinations are possible using the TMS. In the example below, an 8" F4 Imaging Newtonian telescope is carried next to a 102mm refractor which has a guidescope piggbacked on top. Note that EQ6 mounts cannot carry a load like this - this is a demo to show the flexibility of the TMS. The foundation of the setup is the EQ6 Puck which is bolted to the heavy duty Universal Saddle Plate or USP. This supports a 350mm Losmandy Dovetail Plate, which can be moved from side-to-side to achieve balance. The 8" F4 Imaging Newtonian telescope is carried on a 250mm Vixen Dovetail Bar which is held in a Small   Vixen Dovetail Clamp (SVDC), which is in turn bolted directly to one end of the Losmandy plate. All Altair TMS clamps can be bolted to the ends of all Losmandy plates and the VDC can be bolted to each side of the Vixen bars too. On the opposite side, a smaller 180mm Losmandy Dovetail Plate is used to mount an Altair 102mm EDT refractor, which in turn has the 120mm Guide Scope Rings on top to carry a 70mm ED scope. The guidescope rings fit any Altair TMS Vixen Bar or Losmandy Plate and are fastened with two M6 bolts to prevent twisting, unlike cheaper products using only one hole. Each guidescope ring has a flat lower edge for better contact with the plate or bar and hence greater rigidity.
