Open source astronomy tools and hardware

We are a small open-source community focused on building practical, affordable astronomy tools — especially hardware that can be built, modified, and improved by anyone.

Most of our work started from a simple frustration: many astronomy tools were expensive, closed, or difficult to customize. We wanted something portable, affordable, and open — so we started building our own.

Over time, that small personal project grew into a collection of open-source designs, firmware, and supporting tools that others can use, study, and improve.

We are still learning, still improving, and we welcome anyone who wants to join the journey.

What We Build

Our projects mainly focus on open-source astrophotography hardware, firmware, and related tools.

⭐ OG Star Tracker

Repository:
https://github.com/OG-star-tech/OG-star-tracker-

The OG Star Tracker is a fully 3D-printable, upgradeable astronomical tracking mount designed for astrophotography.

Designed to be:

  • Affordable
  • Portable
  • Modular
  • Open for modification

This project includes:

  • Mechanical design files
  • Firmware
  • Electronics documentation
  • Assembly instructions
  • Community upgrades

🔭 OGScope

Repository:
https://github.com/OG-star-tech/OGScope

OGScope is an experimental open-source telescope-related project.

Like many things here, it is still evolving.

Expect unfinished ideas, prototypes, and improvements over time.

Documentation

📚 https://wiki.ogstartech.cn/

The wiki contains:

  • Assembly guides
  • Firmware documentation
  • Hardware explanations
  • Troubleshooting notes

Documentation is always improving, and contributions are welcome.

Our Philosophy

We believe:

  • Hardware should be understandable
  • Tools should be modifiable
  • Knowledge should be shared
  • Improvements should be collaborative

We do not claim perfection.
Many parts are still experimental.

That is part of the open-source process.

Contributing

We welcome:

  • Code
  • Hardware design
  • Documentation
  • Testing feedback
  • Translations

Typical workflow:

  1. Fork
  2. Modify
  3. Submit Pull Request
  4. Describe changes

Even small improvements matter.

License

Each project contains its own license.

Many hardware components are released under:

CC BY-NC-SA 4.0

Please check each repository for details.

Thanks

Open-source only works because people care enough to contribute.

We appreciate every contribution.

Open source astronomy tools and hardware
We are a small open-source community focused on building practical, affordable astronomy tools — especially hardware that can be built, modified, and improved by anyone.
Most of our work started from a simple frustration: many astronomy tools were expensive, closed, or difficult to customize. We wanted something portable, affordable, and open — so we started building our own.
Over time, that small personal project grew into a collection of open-source designs, firmware, and supporting tools that others can use, study, and improve.
We are still learning, still improving, and we welcome anyone who wants to join the journey.
What We Build
Our projects mainly focus on open-source astrophotography hardware, firmware, and related tools.
⭐ OG Star Tracker
Repository:
https://github.com/OG-star-tech/OG-star-tracker-
The OG Star Tracker is a fully 3D-printable, upgradeable astronomical tracking mount designed for astrophotography.
Designed to be:
  • Affordable
  • Portable
  • Modular
  • Open for modification
This project includes:
  • Mechanical design files
  • Firmware
  • Electronics documentation
  • Assembly instructions
  • Community upgrades
🔭 OGScope
Repository:
https://github.com/OG-star-tech/OGScope
OGScope is an experimental open-source telescope-related project.
Like many things here, it is still evolving.
Expect unfinished ideas, prototypes, and improvements over time.
Documentation
📚 https://wiki.ogstartech.cn/
The wiki contains:
  • Assembly guides
  • Firmware documentation
  • Hardware explanations
  • Troubleshooting notes
Documentation is always improving, and contributions are welcome.
Our Philosophy
We believe:
  • Hardware should be understandable
  • Tools should be modifiable
  • Knowledge should be shared
  • Improvements should be collaborative
We do not claim perfection.

Many parts are still experimental.
That is part of the open-source process.
Contributing
We welcome:
  • Code
  • Hardware design
  • Documentation
  • Testing feedback
  • Translations
Typical workflow:
  1. Fork
  2. Modify
  3. Submit Pull Request
  4. Describe changes
Even small improvements matter.
License
Each project contains its own license.
Many hardware components are released under:
CC BY-NC-SA 4.0
Please check each repository for details.
Thanks
Open-source only works because people care enough to contribute.
We appreciate every contribution.
