  • Go2Nova® Handset 8409V2 for select Strain Wave Gear Mounts

    The Go2Nova® Handset 8409V2 is the command center for select iOptron Strain Wave Gear mounts, driven by a 32-bit ARM processor and featuring a vast database of approximately 212,000 objects. Its backlit, 4-line, 21-character display provides clear feedback, while 9 variable slew speeds allow for both rapid repositioning and fine-tuned centering. With integrated USB and Wi-Fi, this handset enables full ASCOM-compatible computer control and ensures your mount's firmware stays current.

    The 212,000+ Object GoToNova Database

    At the core of the 8409V2 handset is iOptron's comprehensive GoToNova database, containing approximately 212,000 celestial objects. This extensive catalog includes everything from the Messier and NGC/IC catalogs to SAO stars, ensuring you can locate and track a lifetime of targets. The 32-bit ARM processor ensures quick, lag-free access to the database, making target identification and GoTo slews fast and efficient.

    4-Line Backlit Display and 9-Speed Control

    Designed for field use, the handset features a red-backlit 4-line, 21-character LCD that preserves your night vision while providing all necessary alignment and object data. You have complete manual control over your mount with 9 selectable speeds, ranging from a slow 1x sidereal rate for precise photographic framing to a MAX speed for slewing quickly between opposite sides of the sky.

    USB, Wi-Fi, and ASCOM for Full System Integration

    The Go2Nova 8409V2 moves beyond basic GoTo functions with modern connectivity. The built-in USB port facilitates easy firmware upgrades and provides a stable, wired connection for computer control. For wireless operation, integrated Wi-Fi allows you to command your mount from a PC or mobile device, eliminating cable drag. Both connection methods are fully ASCOM compatible, enabling seamless integration with popular planetarium software and imaging automation platforms like N.I.N.A. or Sequence Generator Pro.

  • What mounts is the Go2Nova 8409V2 handset compatible with?

    The Go2Nova 8409V2 is designed specifically for select iOptron Strain Wave Gear (SWG) mounts. It is not a universal controller. Always confirm compatibility with your specific mount model before purchasing.

    What kind of objects are in the Go2Nova 8409V2's ~212,000 object database?

    The database is comprehensive and includes the most popular celestial catalogs for amateur astronomers. This includes:

    • Complete Messier, Caldwell, NGC, and IC catalogs
    • Planets, the Sun, and the Moon
    • Named deep-sky objects and stars
    • An extensive list of SAO catalog stars

    How do I connect the Go2Nova 8409V2 to my computer?

    You have two options for computer control with the Go2Nova 8409V2. You can use the built-in USB port for a reliable, wired connection, or use the integrated Wi-Fi for wireless control. Both methods support the industry-standard ASCOM protocol, allowing you to use a wide range of astronomy software.

    Can I update the firmware on the Go2Nova 8409V2 handset?

    Yes. The firmware on the handset is upgradeable. Updates are performed via the USB port using firmware and software provided by iOptron, ensuring your controller has the latest features and object databases.

    How do I use the 9 slew speeds on the Go2Nova 8409V2 to center the Hercules Cluster (M13)?

    After your mount performs a GoTo slew to M13, you would use the higher speeds (like 128x or 256x) to make large adjustments to bring the cluster into the center of a low-power eyepiece. You would then switch to slower speeds (8x or 16x) for fine-tuning the position. For final, precise centering in a high-power eyepiece or on an imaging sensor, the 1x or 2x speeds provide the necessary fine control.

    Can I control my iOptron SWG mount with planetarium software using the Go2Nova 8409V2?

    Absolutely. The Go2Nova 8409V2 is fully ASCOM compatible. This allows it to act as an interface between your mount and any ASCOM-compliant software, including popular planetarium programs like Stellarium, Cartes du Ciel, or TheSkyX. You can click on an object in the software, and your mount will slew to it automatically.
