A free, unofficial desktop companion for the Celestron Origin Intelligent Home Observatory. Live view, full mount control, YouTube & Twitch streaming, and real-time sky conditions — all from your Windows PC.
Built on the same SmartScope WebSocket protocol as the official app — fully reverse-engineered and confirmed from live packet captures.
Real-time camera feed at full 3056×2048 resolution delivered over WebSocket at ~1 fps. Position, firmware and mount status all update live.
D-pad slew with 4 speed levels, Go-To by RA/Dec or object name, sidereal tracking, parking and a one-touch emergency stop.
Stream live to YouTube (OAuth auto-login with QR code) or Twitch via stream key. 480p, 720p and 1080p quality presets. H.264 via FFmpeg.
12 SomaFM stations. Switch stations or adjust volume mid-stream with zero interruption — powered by an audio proxy that keeps FFmpeg running.
Real-time DSO recommendations ranked by current altitude. Uses your telescope's live GPS coordinates. One click to slew directly to any target.
Live sky score from Open-Meteo: cloud cover, dew risk, wind, visibility and precipitation — all scored 0-100 with colour-coded indicators.
Read and write live telescope configuration — camera specs, focuser auto-focus, mount config, dew heater, LED ring brightness and network settings.
Save full-resolution JPEG snapshots or record local MP4 video at any quality. Recording and streaming can run simultaneously.
No admin rights required. The installer handles Node.js and FFmpeg automatically.
Grab the ZIP from this page and extract it to any folder.

Join your telescope's Wi-Fi and click Discover on Network.
Live view starts automatically. Control, stream, and explore.
Celestron Origin Control started as a personal project to bring full observatory control to Windows — the official Celestron Origin app is mobile-only, leaving desktop users without a way to control the telescope from their PC or stream sessions online.
The SmartScope WebSocket protocol was fully reverse-engineered from live network packet captures using PCAPdroid, giving this app access to every command the official app uses — slewing, GoTo, tracking, focuser control, camera settings, and more.
This app is completely free and will always be. If it enhances your nights at the eyepiece, a coffee goes a long way.
Every donation helps fund development time, telescope sessions for testing, and keeping the project maintained and up to date with new Celestron firmware releases.
Support on Ko-fiFree. No account. No telemetry. Just unzip and run.
