FYI it looks like there will be a new stellarmate coming soon. It looks like it is based on the MeLE x86 PC. I saw the post on facebook:??.?
I recently switched from astroberry on an RPI 4 to a MeLe with ubuntu running ekos/kstars/indi/phd2 etc. I couldn't be happier with the new setup. It runs beautifully, and I can still boot into windows for the single app that I need there: PemPRO (maybe there will be a linux version soon?). This should include the kstars/indi updates that I've been making for the GeminiII including but not limited to L6.?
