It's probable, or at least possible, that your supplier will collimate your device before despatching it to you, Ozfifer. The on going collimation will then be up to yourself. The device (whichever you use) simply fits into the focuser - where your eye piece normally sits - and is used solely for collimation purposes. Once you figure that you are pretty close then you take the 'scope outside in the dark of night and do a 'star test' with one of your eye pieces in place (i.e. the collimator is sitting inside on the dining room table and not in the 'scope); this involves looking at a bright star, not a planet, and deliberately moving the image out of focus - both sides. In theory you should see a dark 'dot' surrounded by a halo of light. The dot should look centred within the halo and the halo circular.
Don't be put off by all this information, as I've already mentioned it's finicky but not hard.
P.S. I guessed your penny whistle interest from your 'user name'.
