Welcome to the home of the m3 mounting system, this is modular system that allows those of you who are using the Vixen type dovetail as found on most of the Chinese mounts to upgrade to a system that gives performance similar to the 3 inch mounting systems used on Losmandy, Takahashi and other high end mounts.

Based on reports we have had back from users of the m3 system, they are reporting up to 30% improvements in unguided accuracy when using the m3 setup. If you want to find out more and see the m3 up close we will be at the  Kielder Forest Spring Star Camp and then at the Kelling Heath Spring Equinox Sky Camp in 2011.

So if you want to improve your mounting stability take a look at the m3 system.

We supply also supply a whole range of accessories including power cables, serial cables, counterweights and a whole host of other accessories for the following ranges of scopes, but remember even if you can't find what you are looking for we may be able to supply it or at least point you in the direction of someone who can. For example we are just adding a range of cables and power converters for Takahashi Temma and Temma 2 equipped mounts.

We are also able to supply the complete range of Peli cases including replacement foam inserts and accessories, please get in touch for more info.

We are also at an advanced stage of development on a Bluetooth interface system that is dedicated to astronomical use for a range of mounts, please ask if you want more information.
