I’ve been using the Synscan Polar Alignment routine on my 3 x Skywatcher mounts for about 3 years now with good results ( < 1 arc minute error ) as I have no view of the SCP. I use the alignment tool in BYEOS with my Canon 600D imaging camera set at 3 x zoom which works really well.I defocus my PA star to achieve accurate centering and alignment.

Out of pure interest my question is how accurate is Pole Master as the manufacturer claims accuracy down to 30 arc sec
Since most observing sites in Australia have latitudes of between 22 degrees and 38 degrees at the SCP , one would think less than favourable atmospheric conditions at these lower altitudes would limit the Pole Masters camera to achieve such tight polar alignment even with quality optics / pixel scale and sophisticated software.
When I use my Synscan PA routine my Polar Alignment stars are usually between 45 and 65 degrees in Altitude.

I welcome any comments from users of this product or folk who have progressed from Synscan to Pole Master

Thanks in advance
