Hey guys
I tryed the tightness screw that erick thought of and that seemed to work quite well, only needed a little tweek and the focuser winds slower and easyer to focus. Also yes a 'smudge' on the eyepiece dosnt help when focusing.
just had a look down the scope as well astro, and it seems slightly out. but dont want to touch anything with out someone with me to show me.
thanks heaps for all your help guys.
