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.

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.


LX5 Schematic Drawings

We uploaded schematics we made of the Meade LX5 Quartz Drive electronics (model 2080/2012 telescopes) . Go to the Technical Notes page to view or download them. Also, we documented the process of creating those drawings and used them to understand how the electronics work, on our YouTube channel so if you're interested in reverse-engineering, check out those videos.
