I use it, have it on an RPi4 and am overall very happy with it.
I can now select a target, platesolve, guide, autofocus, expose a sequence, change filters, meridian flip(unattended) and continue on etc.
it’s taken a little while to get it all up & automated, and while it doesn’t love my microtouch focuser and Tak NJP mount, it all still works while I’m warm indoors & sleeping.
The developer Jasem is very helpful & responsive too.
