Hi Andrew,

I did the focusing initially using FWHM and Half Flux Diameter, and then did the long and tedious photo by photo inspections for every 1/8 turn of the fine focuser knob. I went backwards and forwards over the in focus area well over a dozen times and took over 180 photos, very painful. But couldn't find a point that that produced pin point stars without a halo.

I'll also give the fee version of CCD inspector a go and see what it determines (thanks for that Greg).

I did contact AOE and full credit to them that they are more than happy to replace my current scope or to exchange it for a Saxon ED80. They were also surprised CA had occurred with that particular scope.
