Hi Danial & All,

Lots of good guides to collimation in links supplied above that should be enough to get you started. Best "manual" tool is a Cheshire eyepiece, not overly expensive, no batteries (to go flat at the worst possible moment) required. Lasers are just as good at achieving collimation, somewhat easier and more intuitive in use but equally somewhat more expensive (for a proper one that will hold its own collimation).

Tuning a telescope isn't hard and gets quicker with practise. It's a skill. Will probably take some time the first few attempts but eventually, you'll nearly be doing it with your eyes closed in a few moments.

As a side-note, I wish I had a dollar for every time a person has made the following comment, after I said something like "I think your telescope may be out of collimation":

"I was told they were colluminated at the factory"!


Best,

L.
