New! LX200 Classic Fork-Arm DEC Cable

DEC Runaway? One possible cause is a broken connection in the cable connecting the motor encoder to the inside of the fork-arm connection. This is a new replacement for that cable.


New! ETX/Autostar USB-to-Serial Adapter

Our USB to Serial (RS232) Adapter now supports the Meade Autostar 497 controller for ETX and other scopes. It comes with a modified cable for the 4-pin modular jack on the Autostar box, so be sure to mention "Autostar" or "ETX" in your order so we include the proper cable.


LX200 Classic Hand Controller, OLED

We've improved our hand controller by replacing the backlit LCD display with a new OLED display. The new display has a true black background with bright red characters.

Our LX200 Boot Emulator Now Has a Joystick

Like our original emulator, this one handshakes with the LX200 Classic to allow it to complete the start-up process and be ready to accept commands from a computer. But this one also includes a joystick, enabling N-S-E-W movement at all four slew speeds.


LX200 USB-to-Serial Adapter

Connect the LX200 (Classic or GPS) RS-232 port to your PC, using any standard USB male type B cable. This is a true RS232-level interface wired, and tested specifically for the LX200.


Announcing Meade LX10 Circuit Board
