Optec FocusLynx Kit - Stellarvue - with Hand Control and w/o WiFi

This Optec FocusLynx Kit with Hand Control is a proven boon to anyone looking for a more precise and easier level of focus, and now it comes to Stellarvue's focusers as well! Bringing the astonishing ease of use and smooth precision of the FocusLynx to Stellarvue's high end focusers is a pleasure, and we're here to deliver exactly that.


The basic FocusLynx controller is a small, all aluminum case measuring 5 x 3 x 1-inches. On the bottom are well labeled connections for power, network, hand control, and serial cables. On top are two connectors for the focusers to be controlled. All cables are standard off-the-shelf cables with the exception of Optec's proprietary USB/Serial cable which is included in the package. Out-of-the-box, the FocusLynx controller will provide digital control for one focuser stepper motor. A second stepper board can be easily added to convert to dual focuser control. The FocusLynx system was built from the ground up to be fully compatible with ASCOM focuser standards and allows multiple connections from multiple ASCOM clients. That means you can connect up through the FocusLynx Commander (included), Maxim D/L, and FocusMax simultaneously without having to disconnect and reconnect. Automation programs like ACP, CCD AutoPilot, and CCD Commander can access the dual FocusLynx focusers with ease, regardless of the physical connection.

  • Kit for enhancing Stellarvue Focusers with the FocusLynx Control System
  • Fully compatible with ASCOM focuser standards
  • Allows multiple simultaneous connections from multiple clients


Optec FocusLynx Focuser Hub: The FocusLynx Focuser Hub offers an easy way to simultaneously and independently control up to two Optec or Starlight focusers through a computer, smartphone, or hand control. Each focuser may be plugged into the hub using standard serial cables. The FocusLynx can then be connected to a computer via serial cable, Ethernet, or wireless network. Once connected, are ready to go! You can simply open up any focuser control program or Optec's proprietary FocusLynx Commander control software and you will be able to control each focuser the way you would without the hub. The FocusLynx Hand Controller plugs into the FocusLynx to allow telescope-side control of each focuser.


Optec QuickSync SV Motor (For Stellarvue 2.5-inch Focusers): This is a QuickSync SV FocusLynx Motor with built-in clutch mechanisms and temperature sensors, allowing both manual and motorized control with a simple twist of the motor housing. Not only is installation simple, but full compatibility with a FocusLynx Control Hub ensures that this is an ideal choice for motorizing a Feather Touch Focuser.
