Resolved the balance issue see post under equipment.
Run CCD Inspector on a stack of 5 frames of M5 shows a curvature of 39.6% FWMH min 1.85 Max 4.37.
Correct me if wrong but if FWMH is between 2 and 4 would this not indicate reasonable collimation
The curvature % is better than from my ED80 when tracking was spot on however could this high figure be attributable to bad alignment as others posted images on CN show a figure of around 17% in CCD.
and true to form it's cloudy today but still no rain.
Cheers
