Key Features
Adjustable and universal mount for complete focuser compatibility
This versatile universal mount features custom holes and rails carefully designed to ensure seamless integration with any telescopic system.
Whether you have a refractor, a reflector, or another type of telescope, the FocusCube 3 mount can be easily adjusted to suit your needs.

High-resolution stepper motor with gearbox
Equipped with a high-resolution stepper motor coupled with a robust gearbox, it delivers exceptional torque that can easily lift and carry telescopic equipment weighing up to 6kg, even when pointed at the zenith. What is special about this motor system is its high precision, as the play has been carefully minimized to achieve very low values.


Robust motor couplings included in delivery
The package includes a selection of five solid motor couplings, each with a different bore size. This allows you to adapt the coupling precisely to the shaft of your telescopic extension and ensure a secure and precise fit.
With options ranging from 4mm to 8mm couplings, you have the ability to seamlessly integrate the FocusCube 3 into a wide range of telescope setups.


USB and Wi-Fi connection
The FocusCube 3 offers optimized convenience with a single USB-C cable for power and data, reducing the complexity of your telescope setup. It is also Wi-Fi enabled so you can control and monitor focus remotely from your mobile phone.
You can operate the camera via USB or Wi-Fi at the same time, which means flexibility and ease of use for astronomers - all from the comfort of your smartphone.

Successful installation on the following telescopes
Installing the Universal L-Bracket on a variety of telescopic extensions has proven to be exceptionally simple and quick, making it hassle-free for the user.
