I've always had a laptop next to the telescope, running planetarium and imaging software, and so far I've never operated that remotely - it wouldn't contribute much in my use case. But I've been thinking of trying that in the future, and it seems to me that everyone has a computer, be it a mini pc, asiair, stellarmate, on the scope running all the software, and then you remote in to that with vnc or otherwise. But why is that? With indi, and with ascom/alpaca as far as I know, the machine on the telescope can just run the device driver/server and then your ccdciel/kstars/whatever can run on a computer inside and connect to those over lan/wifi.
It looks like no one does it that way - I'm assuming for a good reason but I don't see what it is?
