I would love to know if "Cambridge Blue" is actually blue to the average person, because, to me, it's green...

No MaximDL needed! All built in, including autoguiding and autofocusing.
Satellite tracking to be implemented in the future, working on it these months with a student of mine.
Object scheduling timing is down to the user - but the wait directives does sound like a useful feature!
Custom python scripts are possible, please check out here: https://docs.withastra.io/user_guide/custom_observatories
I also recommend checking out the introduction video that covers install and setup :) https://www.youtube.com/watch?v=QIElFSS1hkA

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.

I just released Astra, so I'm impressed how quickly you got set up!

Not to mention the huge issues of cosmic rays. Sure, if the lifespan of the satellite is expected to be low, then maybe tolerable. But even then, how would this be financially viable?

I'm hoping one of these efforts will lead to local translation of PDFs. Anyone aware of one? Not local, but the best I've found is using Google Translate via camera/images.
