I've got a Celestron autofocuser and to be honest I don't know if it is compensating or not!
Just got the ZWO EAF and am considering the sensor.
If the critical focus of your setup is very narrow, I'd guess temperature compensation becomes, well, critical?
As the whole setup cools down, the more massive components change least, so my plan is to put the sensor near the focuser on my refractor, and on the top of the tube of my SC. On the other hand, bigger components move more physically, as a percentage of change.
Just guessing, though.
I got a sensor with my Pegasus box which is useless 'cos I can no longer communicate with the box- it just distributes power now, so I don't know what the temperature is doing at the scope.
