Selecting an Ocular Lens:
You should always start viewing with the lowest power eyepiece, which in this case is the 20 mm lens.
Note: the base power of each ocular lens is determined by the focal length of the telescope objective
lens, which for this model is 700 mm. A formula can be used to determine the power of each eyepiece:
Telescope OBJECTIVE lens (Primary Mirror) focal length
MAGNIFICATION (e.g. Using the 20 mm lens, the calculation would look like this: 700 mm
or 35 power.)

Enjoying Your New Telescope
1. First determine your targeted object. Any bright object in the night sky is a good starting point.
One of the favorite starting points in astronomy is the moon. This is an object sure to please any
budding astronomer or experienced veteran. When you have developed proficiency at this level,
other objects become good targets. Saturn, Mars, Jupiter, and Venus are good second steps to take.
2. The first thing you need to do after assembling the telescope as planned is center the desired object
in the finderscope's cross hairs. Provided you did a reasonable job aligning the finderscope, a quick
