OG Star Tracker V2

The OG Star Tracker V2 is a travel-friendly tracker built for people who want real sky time—not a complicated setup ritual. It’s light enough to pack, accurate enough for long exposures without immediately needing an autoguider, and modular enough to grow with your ambitions (laser alignment today, declination axis upgrade tomorrow). Add app control, built-in camera triggering with dithering support, and time-lapse panning, and you’ve got a tracker that’s equal parts practical and fun.

• Lightweight & portable design built for travel rigs and quick setups
• High tracking accuracy with 10″–15″ periodic error, enabling longer exposures without an autoguider (especially at modest focal lengths)
• Sturdy and stable payload handling
  • Supports 4kg imaging gear (with up to 5kg total payload noted)
• Easy polar alignment via laser
  • Aim the laser at Polaris for fast alignment—no polar scope required
  • Modular option to swap between laser and polar scope depending on preference
• Modular & customizable ecosystem
  • Add a ball head
  • Upgrade with a manual declination axis
  • Manual GOTO ready for quick target positioning workflows
• Advanced camera control
  • Built-in intervalometer port plus dithering support to help reduce pattern noise in stacked images
• Time-lapse panning for cinematic night-sky motion sequences
• Field-friendly details you’ll actually use
  • Integrated bubble level for faster leveling and alignment
• Open-source design: parts are open source for transparency, tinkering, and long-term serviceability
• Simple power requirements: run it from a common 5V power bank
