SCT Collimation

I have been trying to collimate my Meade 8" f10 SCT, as the planetary views I have been able to get with it are somewhat dissapointing. i.e. Jupiter shows the main two cloud bands and very little else. I can see as much with my ED80.

Got some Bob's knobs to make the job a bit easier, but am unsure as to how accurately SCT's have to be collimated, and what I should expect in terms or performance from this scope. I bought it second hand, so did not get to look through it as new. So far, the seeing up here (Mackay) has only allowed me to collimate with magnification to about 300x, and this has not improved the planetary images.

Any input or suggestions on this subject would be appreciated.

Regards,
David.
