iOptron IEQ west/east reversed? #33756
I saw this issue yesterday with Patrick as we tried the new Ekos Polar Alignment Assistant tool that uses West/East command to move the mount.

So the RA would increases if we slew EAST, and decrease if we slew WEST.

East --> RA+
West --> RA-

This is the expected behavior. However, iOptron CEM60 (and anything based on the ieq driver) behaves the exact opposite of this. Is there some explanation for this?

Odd. The CEM25 works fine in all aspects, except when I use the legacy Polar Alignment tool. I found the instructions given by EKOS to be reversed when it comes to calculating the ALT error (which is done using East/West stars). If EKOS told me the mount was too high, I had to increase its angle even more to get it aligned.

How about when you issue motion West/East command via the INDI or mount control panel, what happens to the RA reading?

Good question, I have never tried. I've only used KSTARS and allowed EKOS to move the mount from the Alignment module.
