For experienced users who already own a Raspberry PI 3 unit, StellarMate OS is a complete software package ready for deployment on your RPI3. It is provided as an OS Image file (.img) that you can burn to an SD card and fire it up immediately to enjoy the full benefit of StellarMate software stack. The following packages are included in addition to the base OS:

  • INDI
  • KStars/Ekos
  • with index files.
  • StellarMate Web Manager.
  • StellarMate Network Manager.
  • StellarMate Serial Port Assistant.


  • Raspberry PI 3
  • 8GB MicroSD. A 16GB+ Class 10 MicroSD card is highly recommended.


After your purchase, you will receieve a link in the email to download the file. Since the file size is ~2.5 GB, it is highly recommended to use a dedicated download manager to download the file. After you download the file (, you can verify its integrity by computing its hash. Use Quick Hash GUI to verify the integrity of the image file. The following are MD5 and SHA256 hashes of the zip file:

  • MD5: bac65deb3ca865a212a31d54364d7f97
  • SHA256: 95ece72b20dbd7ff6dcc0bcb8895734c787780c4f7a190fecbdfa3f2b233992b


Etcher is a graphical SD card writing tool that works on Mac OS, Linux and Windows, and is the easiest option for most users. Etcher also supports writing images directly from the zip file, without any unzipping required. To write your image with Etcher:

  • Download Etcher and install it.
  • Connect an SD card reader with the SD card inside.
  • Open Etcher and select from your hard drive the StellarMate .zip file you want to write to the SD card.
  • Select the SD card you wish to write your image to.
  • Review your selections and click 'Flash!' to begin writing data to the SD card.

Boot up

Once the image is burned to the card, insert the microSD card into Raspberry PI3 and power it up.

Note: StellarMate can take up to 2 minutes before switching to HotSpot mode on first startup.

I would probably give it 4 stars because its a slick tool that can work well. Mount control for go-to and polar alignment and plate solving work well but internal guiding not so much - could use more control to PHD2 - such as launching it. I have the first release but I've been following Kstars/INDI development for 6-8 months and there are still bugs to be ironed out. In spite of that, I've decided to make stellarmate my main tool for astrophotography.
