Thanks guys.
I have the solid tube 8" skywatcher, the mirror is much cleaner than it was but I have to admit I did tighten the screws on the mirror (not the collimation screws) because first time I did the collimation the main mirror 'clunked' whenever I move the dob and this made the collimation out again. So I 'thought' the screws holding the mirror needed to be tightened which has now stopped this mirror movement.
I didn't touch the secondary mirror.
I can see the stars better on a 32mm Plossl Eyepiece - not completely sharp though, but when using a Barlow or simply the 17mm and 8mm Hyperion its worst and blurry and no focus is possible.
I vaguely remembered a while ago on here that somebody had a skywatcher dob and they had some adapter still on the focuser that needed to be removed or something which caused their blurry images.. but anyway I was able to see Saturn well enough before I messed this up so I guess that can't be it.
