Hi Tim, it's been about a year and a half since you posted this, so I'm writing to ask how you ended up solving it. I'm a Mac user, am trying to decide between buying a PlaneWave or an AG Optical scope. An issue for me is the software to run the respective thermal systems. I notice that there are Device Settings in the EKOS Profile setup for both Planewave's Delta-T and EFA (as of version 3.5.2 of kStars--maybe that wasn't the case when you posted). I also notice there are no such settings for AG Optical, which might be enough to sway me to PW...maybe (but not before I speak with AGO).
Did you ever solve this problem for your PW? If so, are you happy with it?
