Thanks for your help Kev, I even managed to get the thing collimated without much trouble at all.
All I did was put the laser collimator in the focuser and adjust the secondary mirror so that when I rotated the laser in the focuser, the circle it made was centred around the dot in the middle of the primary. All I did then was adjust the collimator till the dot was in the middle of the centre spot on the primary. Took all of about 2 minutes.
Now when I rotate the collimator the dot stays in the same spot. I don't know if this is the right way to do it, but it worked for me and it was quite easy.
Cheers
