Found a series of videos on Youtube that should be of interest to everyone, especially newcomers to telescopes.
The videos, all 102 of them, are presented by Astronomy & Nature Tv in the UK.
2 videos on collimation...

If you want to check out all 102 videos

The one on using setting circles on small telescope mounts might make you stop and think!

Anyway, hope somebody gets something useful from them
Cheers
