Hey All,

Quick one (a problem I had a long time ago, which fixed itself.. but now picking things up again i'm having).

My KStars direction / movement is inverted when using ekos to control the mount. My guess is something to do with the southern hemisphere, mount is celestron wifi ALTAZ.

To simplify things in terms of logs, I did a quick connect, and a couple of seconds of *UPWARD* movement. The mount itself moves correctly upward. Logs attached.

Mount location seems to set correctly (KStars location also set to Sydney, Australia).

However in diving into things, it seems the problem is the encoder direction might be inverted? As (see below) the AL output is decreasing rather than increasing.

Am I just completely down the wrong path here? The actual conversion from encoder numbers to AL seems to be correct from my calculation, so is it either that isNorthHemisphere() isn't firing correctly (I haven't found where that sits exactly yet), or does this model of mount have the encoder output reversed?
