USING THE STAR POINTER (con’t)
Without moving the main telescope, turn the StarPointer’s azimuth and altitude alignment controls until the red dot is directly over the alignment star. If the LED dot is brighter than the alignment star, it may make it difficult to see the star. Turn the variable brightness control counterclockwise, until the red dot is the same brightness as the alignment star. This will make it easier to get an accurate alignment. The StarPointer is now ready to be used. Remember to always turn the power off after you have found an object. This will extend the life of both the battery and the LED.
FINDING OBJECTS
Look through the finderscope and pan the telescope until the object appears in the field of view. Once it’s in the field of view, tighten the altitude and azimuth locks.
FOCUSING
1.Once you have found an object in the telescope, turn the focus knob until the image is sharp.
2.To focus on an object that is nearer than your current target, turn the focusing knob toward the eyepiece (i.e., so that the focus tube moves away from the front of the telescope). For more distant objects, turn the focus knob in the opposite direction.
3.To achieve a truly sharp focus, never look through glass windows or across objects that produce heat waves, such as asphalt parking lots.
MAGNIFICATION
The magnification (or power) of a telescope varies depending upon the focal length of the eyepiece being used and the focal length of the telescope.
To calculate magnification, use the following formula, in which FL = focal length:
Magnification = FL (telescope) in mm
FL (eyepiece)
