Here is our selection of mechanical hardware. We produce all our hardware in house using precision CNC machinery. All our parts are from high grade materials and will be delivered anodised (hard coated) to 20 micron thickness. Steel parts can be galvanised or have a coating of choice.

While we are working on a ready-to-ship catalogue of standard accessories, please email us to order your custom hardware from any of the categories below.


Actuators are used to automate a telescope system, e.g., upgrade dust covers, focusers, filterwheels, individual telescopes in small arrays, providing safety features such as hard or soft stops to prevent damage.

Spacer Barrels

Spacer barrels are used to set the correct spacing for elements such as coma correctors or focal reducers/extenders. They can also be used as adapters to join different systems together.

Pier Adapters

Pier adapters are used to attach a mount to a fixed pier or a 3rd party tripod. We have these in all common sizes and also can make custom adapters to order.

Mirror cells

We specialize in precision manufacturing of computer optimised cells to hold optics. This can be an upgrade to a poorly designed cell, addition of side supports or for ATMers.

Tube rings

Tube rings are used to hold a telescope to the mount, custom systems can be made that hold more than one telescope or to fit an unusual diameter scope that you cannot find standard rings for.


Our dovetails are all universal and can connect any commonly encountered fitting to a mount using any kind of common fitting such as Vixen or Losmanday dovetail. It’s also possible to make totally custom dovetails.

Guide Rings

Guide rings are needed for adjustments of a guide scope for tracking purposes. Custom guide rings will allow you to benefit from a greater range of motion, a stiffer assembly and high quality handles that are easier to adjust and will hold the guide scope without any risk of damaging the surface.

Secondary systems

These category relates to any type of conversion of the secondary assembly of a telescope, including upgrading to an automated focuser, systems that allow switching of the secondary mirrors in dual configuration telescopes or conversions from one optical system to another.
