For those who are interested, there is a new distribution that works very well on raspberry. This is AstroArch. It installs very easily on pi4 or pi5. It is in x64, all software is with the latest version, works in HDMI or VNC, KDE6.
It also contains the astromonitor software. It allows you to save the kstars, indi, phd2 and equipment profile configuration files on a server. You can thus recover your configurations to reinstall them on another device or in the event of a hardware failure.
