There are 3 hex screws to adjust and although it took a while I eventually managed to get it dead center -- according to the collimation laser anyway.

Thanks for the tip!
Forgive my ignorance, as I'm new to all of this and I've only used a refractor which don't need collimation so I'm not 100% sure what all of this means. Is it correct to say that incorrect collimation will result in optical aberration known as coma? And if so, would I be correct in thinking that the attached image is demonstrative of this phenomenon?
If that's so, can you, or anyone else suggest a good / cheap way of resolving this... don't really want to spend a lot if it's a one-off event.
