ASEW

Autostar Emulator for Web Browsers

Free yourself. Control your telescope from anywhere.

The AUTOSTAR Emulator for Web Browsers (ASEW) is the modern replacement for failed/failing MEADEยฎ hand controllers. Powered by the ESP32-S3, ASEW connects directly to your telescope over RS-232 and transforms any device โ€” laptop, tablet, or smartphone โ€” into a wireless hand controller.

Whether youโ€™re at the eyepiece or across the yard, simply open your browser, connect over Wi-Fi, and enjoy full AUTOSTAR functionality in a clean, touch-friendly interface.

Why ASEW?

  • โœจ Free yourself from the cord โ€” no more being tethered to a coiled handbox.
  • ๐ŸŒ Works everywhere โ€” Windows, Mac, Linux, Android, iOS โ€” if it has a browser, it works.
  • โšก Zero learning curve โ€” The interface mirrors the original AUTOSTAR hand controller, so you already know how to use it.
  • ๐Ÿ”Œ Plug-and-Play โ€” Powered by the ESP32-S3, with built-in Wi-Fi and a KISS (Keep It Simple, Stupid) setup philosophy.
  • ๐Ÿ“ก Always up-to-date โ€” Built-in OTA (Over-The-Air) firmware updates, so you can upgrade straight from your browser with no cables or special tools.

Compatibility

  • โœ… Full Replacement: Works seamlessly on mounts that use AUTOSTAR II or AUTOSTAR III (e.g., LX200, LX600, LX850, LS series).
  • โš ๏ธ Other Models: For scopes using AUTOSTAR 497 / AUDIOSTAR (LX90, LX85, ETX, LXD75, DS, etc.), ASEW may still provide remote control, but it cannot always replace the handbox since the RS-232 port lives on the controller itself.
  • KISS server automatically discovers the handbox model and updates the button labels accordingly.

Tested & Proven

ASEW has been successfully tested across multiple platforms and screen sizes, delivering a smooth, reliable, and portable telescope control experience.

๐Ÿ‘‰ In short: ASEW lets you free yourself from the hand controller โ€” and take full control of your telescope from any device, anywhere.
