Hi Susie, a couple of basic pointers. Telescopes generally have a narrow
field of view, making it hard to find things in the sky, so they have a smaller
scope [known as a finderscope] attached to them which has a wide field of view rather like looking through one side of a pair of binoculars. When you
have located your target with the finder you then put a low power eyepiece
into the main scope's focuser and locate the object in the main scope and rotate the focuser knob to obtain a sharp image. All this assume that the
finder is well aligned with the main scope. To check this aim the main scope at something a few hundred metres away during the day, and use the three adjusting screws on the finder mounting bracket to align the finder onto the same object.
The eyepieces have a number in millimetres on the side, such as 24mm.
The higher the number the lower the magnification and vice versa.
Hope this helps you get started
