For those who want to do away with the task of manually focusing altogether, we are pleased to offer the optional USA-made Radian Autofocuser as an immediate automation upgrade specifically designed for the Radian 61 Telescope and the Radian 75 Telescope but compatible with any 2.5", 2.7" or 3" Feathertouch focuser.

We know some prefer not having to second-guess focus accuracy by hand, or would rather control their system from inside on colder nights. The Radian Autofocuser's high-resolution stepper motor allows you to adjust focus directly (without an additional focus controller) via software from your computer to ensure you get perfect focus automatically every time.

• Extreme Precision High-resolution stepper motors allow for the finest micro-adjustments to be made so you can dial in razor-sharp focus.

• No More Second Guessing Using focus automation software, you don't need to waste unnecessary time trying to double and triple check focus. By using V-Curve models to automatically identify the best focus position, software can accurately find perfect focus on the first try.

• Versatility With Nearly Any System Unlike other focusers, the Radian 61 Electronic Focuser is compatible with all ASCOM, X2, and INDI software, making it compatible with Windows, Linux, and Raspberry Pi operating systems, with Mac support coming soon. Please note this product is not compatible with the ZWO ASIAIR Pro due to limitations by ZWO.

• Manual Override For those moments when you just want to focus by hand, an integrated clutch releases to allow use of the manual focus knobs.

• Ultra Lightweight Too many focusers add unnecessary weight and unwanted torque into your imaging train. Weighing just 6.4 oz (185 g), the Radian Electronic Focuser can even be used on a travel-friendly star tracker mount.

• Goodbye Focus Controller Many electronic focusers require a bulky additional focus controller just to control the focuser itself, which adds unnecessary weight and more cables to get snagged on. We decided to cut the middle man and just allow the focuser to connect directly to your computer via included USB cables, eliminating unnecessary parts.

• Low Power Draw The focuser draws less than 1 amp of power at all times, making it easy to power even with your computer by using a third-party USB to 12V DC converter cable.

• Designed to work with the Radian 61 Telescope and the Radian 75 Telescope.
• Compatible with any 2.5", 2.7", and 3" Feathertouch focuser.
• Automated system to get extremely accurate focus on the first try
• Compatible with ASCOM, X2, and INDI software for versatile use with Windows, Linux, & Raspberry Pi operating systems with Mac compatibility coming soon
• Please note: the Radian Electronic Focuser is incompatible with the ZWO ASIAIR Pro
• Included power supply and USB cables for connecting directly to your computer with no additional focus controller needed
