Hi Dave, the main problem im having is getting the secondry mirror centred. I have it centred along the lenght of the scope but i carnt get it to go 'up and down' if you know what i mean!?! The spider has two veins with 3 screws (one vein is 'L' shaped) but losening/tighteng them doesnt adjust its position, it just makes it lose! I'm hoping to get my first view of Saturn soon (when it stops raining!) and i want my collimation to be bang on!
Are lasers worth the money?

Cheeers for the advice so far, i'm sure ill get the hang of it in the end!!!
