Hi Mark,
Didn't mean to insinuate that you don't know East from West, the you in my post was generic.
But left and right are reversed if the mount is pointing north vs south. If you consider how the mount would be setup in the northern hemisphere, pointing at the NCP the mount is rotated 180 degrees from that position in the SH. When you do this the left hand knob becomes the right hand knob and
vice-versa. Even though the west and east knobs are also reversed in the above situation, the azimuth rotation in the report give a deviation from true south in degrees east or west, so you have to adjust the other way, it's all in the way the software is written. IMHO the change to left and right has attempted to make the adjustment simpler, but has, in fact, made the adjustment more difficult because it is dependant on the position of the person making the adjustment. Whereas once east and west are established they are observer independent.
Cheers
Stuart
