NS-3000 is an unofficial derivative firmware based on the open-source telescope controller OnStep. This version is configured with SLEW_RATE_BASE_DESIRED = 0.8, which provides GOTO speeds covering approximately ×100, ×200, and ×400, depending on the mount configuration. It is intended for standard to high-speed stepper motor setups. This package includes a precompiled firmware binary that can be written directly to an ESP32. Compiling the source code is difficult for most users, therefore flashing the included binary is strongly recommended. ※ This is NOT an official OnStep release ※ Use at your own risk
