WiFi-nFOCUS is a computerized motor focusing system for Celestron and Meade SCT telescopes, operable via WiFi from PCs, tablets, and smartphones. It offers temperature compensation, modular design, and supports advanced autofocus software, enhancing precise telescope focusing.

The WiFi-nFOCUS from Rigel Systems is a computerized motor focusing system designed for Celestron and Meade SCT telescopes. It can be operated from PCs, tablets, and smartphones using WiFi and is fully ASCOM compliant, ensuring compatibility with popular focus control programs. The system includes a temperature compensation feature with a dedicated sensor.

Measuring approximately 1.5 inches wide by 4 inches long and 0.5 inches thick, the WiFi-nFOCUS is powered via USB or a 12V battery. The gear-coupled motor prevents binding of the focuser shaft and provides 4300 steps per revolution, supporting focusing speeds of up to 300 degrees per second. The motor weighs 160 grams and does not interfere with the mount at high altitudes or declinations.

Introducing WiFi-nFOCUS: New electronic focuser option for Celestron and Meade SCTs arrive

Kits are available for Celestron models made since 2006, and for pre-2006 models. Meade kits fit their full range of sizes and models. The WiFi-nFOCUS is modular, allowing users to purchase only the components needed. The temperature sensor has 0.1-degree Celsius resolution and can be attached to the telescope for accurate ambient temperature measurements.

Included in the package are the WiFi-nFOCUS unit, USB PC cable, focus motor cable, 12V DC wall adapter cable, focus motor, bracket, gear kit, and all necessary hardware. The motor can be declutched for manual focusing, and the system supports standalone operation via WiFi from smartphones or tablets.

Since 2010, the WiFi-nFOCUS has been installed in over 1,000 systems and is compatible with advanced autofocus software, including ASCOM and INDI drivers. The modular design allows for easy repair or replacement of components.
