Premium Mechanics and a Compact Body

The ESATTO robotic microfocuser stems from our extensive experience in astrophotography and embodies the hallmark quality of PrimaLuceLab. Crafted with a dedication to excellence, we aimed to deliver the finest motorized focuser available, integrating cutting-edge technical features into a compact and elegant design, measuring only 67mm thick.

Featuring a unique Crayford design with 18 ball bearings, the ESATTO 2” boasts an impressive payload capacity of 5 kgs (11 lb) while maintaining the smooth focusing required by modern astrophotography techniques, such as autofocusing with V-curve. With a draw tube offering 51mm of free aperture and 15mm of travel, the ESATTO 2” achieves an exceptional resolution of 0.04 microns per step, ensuring precise and detailed imaging results.

Compatibility and Remote Control

PrimaLuceLab recognizes that a dependable link between the focuser and camera is paramount for optimal performance. Instead of the typical 2" visual back, ESATTO 2" is equipped with an M56x0.75 male thread, facilitating attachment of SkyWatcher/Orion reducers for ED 80, 100, and 120 refractors. Additionally, ESATTO 2" offers a comprehensive selection of optional camera adapters with a stop ring, enabling direct connection to commonly used DSLR, mirrorless, CCD, or CMOS cooled cameras.

The stop ring included with these adapters allows for secure locking of the camera at a precise angle, facilitating improved framing of the object being photographed. Available in various sizes, the stop ring adapters ensure maximum rigidity and convenience, enabling easy connection of any camera or accessory with confidence.

Connect to ARCO

With just one cable, you can seamlessly link ARCO for remote control of your robotic camera rotator. ESATTO comes with a dedicated port for direct connection to ARCO, facilitating effortless collaboration between the two devices. With ARCO, you gain remote control over your camera's rotation angle, ensuring precise framing of your desired subject. Engineered to complement each other, ESATTO and ARCO require only a single short interconnect to operate in tandem.
