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 focus
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) in mm
SOLAR OBSERVATION
CAUTION! Viewing the sun can cause permanent eye damage. Do not view
the sun with this product or even with the naked eye. Never leave a telescope
unattended during the daytime; a child could look at the sun with it and
suffer permanent damage to vision.
THE MOON FILTER
A moon filter has been included with your telescope for removing glare and
increasing contrast when viewing the moon. To attach it to the telescope eyepiece,
screw the filter onto the threaded end of the eyepiece.
CAUTION! The moon filter should only be used to view the moon. It is not
intended for viewing the sun. Viewing the sun through this telescope (with
or without the filter), or even with the naked eye, can cause permanent eye
damage.
