It seems that i can roughly align the mirrors (there are two?!?! - i can only see the one at the very end of the tube...) as there are plenty of diagrams in the manual to help.
Thanks for the viewing info too.. shame about the moon tho...

Yes Steve, just follow the manual's description for alignment by eye and you'll get it good enough to get started. Just hoping the previous owner hasn't got it way out of collimation. If things have worked loose, the most troublesome problem would be if the secondary mirror has rotated around the central axis so it is not reflecting light back towards the focusser. But easily fixed, because you can see through the focusser and work out what is going on.
ps. Tonight will also be good. Sneak a look at the sky tonight so you know where to point to tomorrow night and you can seem so knowledgeable!
