their positions during any 2 or 3 hour observing session, the platform on which the telescope is sitting (the Earth) rotates once every 24 hours underneath these fixed objects. To keep astronomical objects centered in the field, simply move the telescope on one or both of its axes (vertical and/or horizontal), using the altitude control handle (5, Fig. 1) as appropriate. At higher powers, astronomical objects will seem to move through the field more rapidly. 4. Avoid touching the eyepiece whil

CALCULATING POWER The power, or magnification, at which a telescope is operating is determined by two factors: the optical, or focal length of the telescope’s main (objective) lens and the focal length of the eyepiece being used. The focal length of the Telestar 40AZ-T’s objective lens is 600mm. To compute power, divide the focal length of the eyepiece into the focal length of the objective lens. The resulting quotient is the magnifying power of the telescope when used with the eyepiece in q
