Today I've checked for updates (sudo apt get update...) and I have seen that kstas 3.5.3 is at last ready for update.
I have updated it (after backing up my SD, of course).
Bad news for me:
- Lx200 OnStep driver is not the latest one (the one that includes rotator support)
- Artificial horizon vs sky colors have been swapped
- PHD2 does not connect with my mount (indi works, but does not connect to the mount) and exits after retrying.
