Astrophotography stacking and processing for Mac, Windows and LinuxDrop your frames in.Get a finished picture out.
- Deep sky: no separate PixInsight, Siril or DeepSkyStacker
- Planets: no separate PIPP, AutoStakkert or RegiStax
- The Moon and the Sun: stacked and finished in the same app
Give it a folder of light frames, with darks, flats and bias if you have them, or a video of a planet, the Moon or the Sun. It calibrates, aligns and stacks them, removes the gradient, balances the colour and sharpens the result on its own. You never have to touch a setting; every control is there if you want to change something.

Opening it on a Mac
- Open the .dmg and drag Akastroid to your Applications folder.
- Open Akastroid from Applications. It opens like any other app.
Signed with an Apple Developer ID and notarised by Apple since 1.3.14, so macOS does not ask you to allow it.
Opening it on Windows, the first time
- Run the installer you downloaded.
- If Windows shows "Windows protected your PC", click More info, then Run anyway.
- Open Akastroid from the Start menu.
Shown once because the app is not code signed yet. The file itself is fine.
Opening it on Linux (beta), the first time
- In a terminal, in your Downloads folder:
chmod +x Akastroid_*.AppImage - Double-click it, or run
./Akastroid_*.AppImage. - If it does not start on Ubuntu 22.04 or later:
sudo apt install libfuse2.
The Linux build is new: if something does not work, write to hello@akastroid.com. Linux reads SER and AVI video; MP4 is not supported there.
