Most people focus their attention on magnifying power when they consider purchasing a telescope.
This is probably to be expected since the whole point in buying a telescope is to enlarge far away objects. Also, a telescope's magnifying power is usually the main characteristic described by the manufacturer. However, magnifying power is certainly not the single most important factor to consider. If you are looking at planets, the moon, or terrestrial objects, then you probably want all the magnifying power you can get. This means that if you have the moon filling the vision in your scope, then within two minutes the moon will totally vanish from your field of vision.
