Bathurst77,
Have a look at this site
www.andysshotglass.com and it should steer you in the right direction. As a complete beginner I found this site very helpful. I also googled the word "collimation" and looked at a few other ideas on collimating and between them
I think I succeeded in the end.
Wavelandscott, thanks for the encouragement. When these clouds clear I'll be heading out to align my new telrad and then I should really be able to find what I'm actually looking for!
