Henry ★★★★★

The control board was surprisingly easy to wire up, and the motor engages the Feather Touch focuser with zero backlash. I’m getting crisp focus adjustments now without any image shift.

Chloe ★★★★★

I was tired of manually adjusting focus on my telescope, so I finally got this digital kit—it's a game changer. The single control board makes installation straightforward, and the motor is surprisingly quiet during operation.

Michael H. ★★★★★

Installed this on my 3.5" Feather Touch focuser and the single control board made wiring straightforward. The digital kit responds instantly, which saves so much time during imaging sessions.
