TELESCOPE USE SELECTING AN EYEPIECE: 1. You should always start viewing with the lowest power eyepiece, which in this case is the 25 mm lens. Note: the base power of each eyepiece is determined by the focal length of the telescope objective element, which for this model is 1000 mm. A formula can be used to determine the power of each eyepiece: telescope OBJECTIVE mirror focal length EYEPIECE focal length = MAGNIFICATION (e.g. Using the 25 mm lens, the calculation would look like this: 1200 m

The reason the sky seems to move daily just as the sun and the moon "move" across our sky, is that the earth is rotating about its

Nebulae--The Great Orion Nebula is a very well known night sky object. This and many others are brought to you by this telescope. Star Clusters--View millions of stars densely packed in a
