It's been great. We've been operating with it at our observatories (SPECULOOS, ESO Paranal, Chile) for the past 2 years without issues that can be attributed to Alpaca. We had to modify the Alpyca library timeout from 5 to 60s (which Astra uses) given our legacy ASCOM drivers not being as compliant as they should be, but other than that it has worked well.
