Checked with a handful of recent images and it works as expected on a Raspberry PI (4GB + Astroberry 2.0.3). If I compile and install stellarsolver from the colorChanel branch and then build KStars, it will use this new version, isn't it?
By the way... do you know if a local .deb package could be built from the local compilation? I'm asking, because my development machine is not the same that the one I use to drive my equipment
