Finding Objects - Bushnell 786050 Instruction Manual

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.
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.
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.
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
