Thanks guys. It appears this scope goes deeper than the original, perhaps due to the precision offered by the feathertouch focuser and other various factors like active cooling, better collimation and Peter's cleaning job on the mirror
Only thing left to do is finalise alignment of the secondary mirror and get some darned clear skies - and seeing! Saturday looks good, might try for Serfert's Sexytet and a few other's from Les's column in the recent S&T.
