That should make life a little easier for the next few weeks.
Gaz,

Good to hear the focuser issue solved.

You need to tighten the collimation screws up not unscrew them. You need to turn them clockwise until you can't go any further. Then unscrew each screw about 2 full turns then re collimate the scope from there. If you unscrew the collimation screws too far they come out and the mirror and cell assembly end up loose in the tube which could damage a few things

Irish,

When collimating, after screwing all screws in as far as they go and then loosening them a bit, only use the two easiest screws to reach to do all adjustments. You only need to adjust two leaving the third to act as a depth guage.

Cheers
