I originally bought this for my Sky-Watcher Esprit 120 and used it for a year with fantastic results. I ended up selling the scope about a year ago and held onto this, but it's time to finally let it go. It fits Esprit 100, 120, and 150 focusers. This is an incredible autofocus upgrade featuring a built-in control circuit in the endcap—meaning no external FocusLynx hub is required. Just provide 12V power and a USB cable to your PC. Delivers 1.1-micron step resolution for perfect V-curves and retains the signature Optec manual override clutch.


  • Condition: Excellent (Used for about a year)
  • Includes: Motor unit, required cables, and all original mounting hardware.
  • Price: $299 (Retail: $495) — PayPal fees and shipping included.


Clear skies and thanks for looking!
