TS Starway 500mm Dual Side-by-Side Telescope Mounting Plate - Losmandy Style for Two Optical Tubes
Starway dual mount for two telescopes on one mount with wide distance for big telescopes
The optical axes of the two clamps are 430mm away that allows to mount very large telescopes next to each other
Losmandy-type clamp on both sites and the connection to the mount is also via a Losmandy-style dovetail bar.
The large 3" double clamp allows the parallel connection of two tubes on one mount. Especially for astrophotography this stable way of parallel mounting is very popular.
Advantages of this double mount:
The mount gets less stress due to the advantageous leverage. The overall rigidity increases, as the guide scope is much nearer to the centre of gravity of the mount in comparison to a piggyback installation on the main scope.
To lower the burden of the mount, the TS double mount has been designed to be very lightweight. Furthermore, the clamping mounts are very flat, that improves the leverage situation.
Connection at the mount side:
On the mount side the TS double mount bears a solid aluminum dovetail bar which fits to all standard mounts on the market which bear a 3" connection. This bar with its 50 cm length is quite long, hence you get also quite large tubes mounted in parallel together. The optical axes are 430mm fare away.
Compatible mounts include:
- Losmandy GM 8, G 11 or Titan
- Celestron CGE or CGEM
- Fornax 52, 100 and 150
- Large 3" Baader dovetail prism clamp
- Gemini ( with original quick release )
Connections at the telescope side:
At the telescope end the TS double mount bears two 3" dovetail clamps of TS Optics. Each clamp is compatible to all 3" dovetail bars mentioned. You can connect your telescope at each of the dovetail clamps as you usually attach it to the mount directly.
How to balance the telescope:
In contrast to the usual piggyback guidescope mounting method you can bring the system into equilibrium easily when using the double mount.
1. Balance the telescopes by moving them back or forwards in their tube rings.
2. Balance the whole system by aligning the dovetail at the mount until there is no imbalance any more.
3. Finally align the imbalance by the counterweights.
.... and the astrophotography session can start !
