Apologies if this is an FAQ, but...

Am I going mad? The azimuth scale on my new Sky-Watcher AZ4 mount increases in degree units in an anti-clockwise direction.

i.e. if you align 0 with north, and rotate the telescope so the scale increases, the scope moves in a westerly direction.

Isn't that the wrong way around?

Have I misunderstood the way the scale works??

In the picture below, the scale remains stationary, whilst the top of the head is the part that rotates.

Northern hemisphere azimuth starts with north as 0 east 90 south 180 west 270 It all is in a clock wise direction facing south, Look at any aviation map 0-360 degrees west is clockwise!

Yes that's what I thought. I wonder why the SkyWatcher AZ4 has the scale going anti-clockwise then?

That's very weird...

P.S. "Northern hemisphere"? - surely the AltAz scale is the same both north AND south of the equator?
