SESTO SENSO 2

SESTO SENSO 2 from PrimaLuceLab: Advanced Electronic Tuning Engine

PrimaLuceLab's SESTO SENSO 2 is an advanced, compact and precise electric focusing motor designed to automate focusing on a wide range of telescopes. With its integrated design, modern features and extensive compatibility, it's ideal for astrophotography and visual observation.

Advanced technical features

• Exceptional precision: Thanks to its stepper motor, the SESTO SENSO 2 achieves a focusing accuracy of 0.7 microns per step, guaranteeing ultra-fine adjustments.
• Compact design : Compact dimensions (87.5 x 64 x 43 mm) integrate motorization, electronics and WiFi in a single housing.
• Vibration-free : Advanced motorization ensures smooth, vibration-free focusing, essential for long exposure astrophotography.
• Thermal control : Compatible with an optional temperature sensor to automatically compensate for thermal variations affecting focus.

Mechanical interfaces

Input interface (telescope side) :

• The SESTO SENSO 2 uses Self Centering Clamp (SCC) technology, a self-centering clamp that allows direct installation on most eyepiece holders on the market without the need for external brackets.
• Compatible with focusers from popular brands such as Sky-Watcher, TS-Optics, Takahashi or GSO. Optional adapters are available for specific configurations.

Output interface (accessory side) :

• The SESTO SENSO 2 is designed to integrate directly with the ARCO rotator/derotator via a dedicated port. This short, direct connection ensures perfect synchronization between the two devices for precise rotations.

Connectivity and control

• Robust USB-C port : Allows reliable connection to a Windows computer or EAGLE system. The USB-C cable supplied is reversible, making it easy to connect in the dark.
• Integrated WiFi : Wireless control via Virtual HandPad on smartphone or tablet. WiFi works even if the SESTO SENSO 2 is simultaneously connected to a computer.
• Compatible software : Works with FOCUSER Manager software, ASCOM driver and PLAY software for intuitive, centralized management.

Additional features

• Customizable LEDs : The indicator lights can be adjusted in brightness or switched off to avoid light pollution during observation.
• Practical presets : Pre-set positions can be stored to facilitate rapid adjustments between different optical configurations.
• Manual operation possible : The focuser can be operated manually without disengaging the SESTO SENSO 2.
