Something to consider is that sooner or later your scope will go out of collimation. If your scope is out of collimation you will notice that your defocused star ie the small donut will not have concentric rings. The rings will touch another somewhere or look like they are nearly touching each other. At low magnification you will not notice too much if your collimation is out. It is when you get up near 400x that you will miss small amounts of detail. Good collimation is a matter of practice and you should not be afraid to undertake this maintenance task. At the very worst you might muff it up. In which case you can either get some help from a local astro club or go to an astronomy shop and get them to help. However, the sooner you get into the habit of doing this task the better. At present you may not have to do anything, knowing when and how to collimate is most important to get the most out of your scope.
