Unhappy SynScan polar alignment bug

It appears that the latest version of SynScan for EQ mounts (v.3.32) has a bug in its polar alignment procedure.

The routine seems to be assuming a northern hemisphere setup with the mount pointing north. During polar alignment the altitude ("elevation") error is being corrected nicely and can be diminished after just a few steps. The azimuth error however roughly doubles with each run of the procedure.

This can be worked around during the polar alignment routine by bringing the alignment star as close as possible to the crosshairs via the altitude adjustment screws first and then using the azimuth knobs to not bring the alignment star into the crosshairs but doubling its distance from it.

After several public betas it's disappointing that this bug made it into the release and I hope it gets squashed soon. If I can find a feedback link for SkyWatcher I'll report it to them.

Cheers
Steffen.
