Global Network of Telescopes. Clear Skies. Always.

We Build a Distributed Network of Telescopes

At INDIHUB we believe that everyone should be able to watch the stars at any time.

With the clearest skies, from any geo-location and with the best equipment possible.

Our global network of telescopes available remotely via Internet - makes this happen.

We Build the Platform for Sharing Astro-Photography Equipment

The technology is ready. Everybody is just using it individually in isolation.

Your astro-photography equipment can be easily connected to our network thanks to the open INDI standards.

Imagine that thousands of people around the world do the same. You use their equipment, they use yours.

We Build Powerful Scientific Tools, Algorithms and APIs

What if we tell you that images taken by your camera can be used in different science projects?

Finding new asteroids, planetary defence, satellites or space junk tracking, to name a few.

Every single image from your main or auto-guiding camera counts.

How to Become a Host on Our Network

Host is the one who provides remote access to astro-photography equipment.

  1. You have a stable high speed Internet connection.
  2. Your equipment is controlled by INDI-server launched via INDI-server Web Manager.
  3. You use PHD2 for auto-guiding (this is optional but highly recommended).
  4. Create and save your devices profile which you would like to share with others. Make sure it is active and loaded on INDI-server via INDI-server Web Manager. I.e. it can be done with KStars/Ekos:

    When you press "Save" - INDI-profile is created and loaded on INDI-server running on raspberrypi.local:7624, the auto-guiding will be performed with PHD2 running on localhost:4400 (don't forget to run your PHD2!). You can now close KStars/Ekos.

  5. Download INDIHUB-agent pre-built binary (or build your own from the source code):
  6. Run INDIHUB-agent with specifying host and port of INDI-server Web Manager and PHD2 running on your local home network. Agent will output publicly available endpoints to access your local INDI-server and PHD2:

  7. Please Provide your guest with this remote access information, also provide information about your main and guiding telescopes (focal length and aperture) and auto-guiding method.
  8. Just press CTRL+C when remote imaging session is finished.
  9. Make sure you have clear skies and excellent polar alignment before you start sharing your equipment. You might be invited by your guest tomorrow to try some new filter wheel or CCD camera you've been always dreaming about. Who knows!

How to Become a Guest on Our Network

Guest is the one who wants to do a remote imaging session on a shared equipment.

  1. Install KStars software or any other INDI client.
  2. Find your host! Ask your friends, post question on forums, chats or social media. You will need to find someone who is already on INDIHUB network.
  3. Ask your host about remote connection info:
    1. INDI-server host and port
    2. PHD2-server host and port (optional)
    3. Focal length and aperture for main telescope
    4. Focal length and aperture for guiding telescope
    5. What type of auto-guiding is used - PHD2 or guiding camera via mount
  4. Imagine your host provided you this remote connection info:
    1. for INDI-server host and port
    2. for PHD2-server host and port
    3. 600mm focal length and 120mm aperture for main telescope
    4. 162mm focal length and 50mm aperture for guiding telescope
    5. auto-guiding via PHD2
    6. main camera ZWO ASI 385MC
    7. guiding camera ZWO ASI 120MM mini
  5. Setup your client software to connect remotely. I.e this is how it looks like in KStars/Ekos.

    NOTE: You don't have to select any devices as shown above, all devices will be loaded per active INDI-profile on remote host. However, you will have to select at least 1 CCD device to connect (just pick any).

  6. Don't forget to select checkbox "Site info" - you will be teleported to a another part of Earth! Press "Save" and then press "Connect" in Ekos. You can always re-connect by the way, as long as remote imaging session is active.

  7. You are connected! It is time to start your imaging session.
  8. Let your host know when you are finished and disconnected. Don't forget to say thank you for hosting this remote imaging session!

Clear Skies! Always.
