[. . . ] The Moon is best observed during its crescent or half phase when sunlight strikes the Moon's surface at an angle. No shadows are visible during a full Moon, causing the Moon's surface to appear flat and low contrast. Deep-Space: These objects are best viewed at a dark site, away from city and other lights. Such objects include nebulae, galaxies, multiple star systems, and star clusters. Terrestrial objects: Your telescope may also be used for high resolution land viewing. Terrestrial observations should almost always be made using a low power eyepiece (50X or less) for bright, sharp images. Land objects offer limited applications at higher powers because the telescope is being pointed through the thickest part of the Earth's atmosphere. 1 Meade 50mm Compact Refractor Telescope d e f g h i c b 1) · · · j 1! 1@ · POWER The power, or magnification, of a telescope when used with a particular eyepiece is determined by two factors: the focal length of the telescope's main (objective) lens and the focal length of the eyepiece being used. To use the 3X Barlow lens, place the Barlow into the telescope focuser tube, followed by the eyepiece. The magnification values available with your eyepieces are as follows: Eyepiece K17. 5mm K12mm K9mm Power 20X 30X 40X With 3X Barlow Lens 60X 90X 120X Fig. Optical Tube Focus Knob Eyepiece Eyepiece Thumbscrew Roof Prism Diagonal Prism Thumbscrew 7. Tripod holder Tripod Platform Dew Shield 2 USING THE TELESCOPE When the telescope is assembled, you are ready to begin observations. 3 WARNING: RECOMMENDED FOR CHILDREN OVER THE AGE OF 5 WITH ADULT SUPERVISION ONLY NEVER USE THE 50AZ-T COMPACT REFRACTOR TELESCOPE TO LOOK AT THE SUN!LOOKING AT OR NEAR THE SUN WILL CAUSE INSTANT AND IRREVERSIBLE DAMAGE TO YOUR EYE. EYE DAMAGE IS OFTEN PAINLESS, SO THERE IS NO WARNING TO THE OBSERVER THAT DAMAGE HAS OCCURRED UNTIL IT IS TOO LATE. Observing land objects during the daytime is a good way to become accustomed to the functions and operations of the telescope. At night, try observing the Moon first, if it is visible, or a bright star. Use the K17. 5mm eyepiece and center an object in the telescope's field of view. The included K17. 5mm eyepiece is the best eyepiece to use for the initial finding and centering of an object. The low power K17. 5mm eyepiece presents a bright, wide field of view, ideal for terrestrial and general astronomical observing. For lunar and planetary viewing, switch to a higher power eyepiece such as the K9mm. If the image starts to become fuzzy as magnification is increased--back down to a lower power. [. . . ] To attach the optical tube to the tripod, first unfold the tripod legs (8, Fig. 1) into the tube at the back of the optical tube and tighten the diagonal prism thumbscrew (6, Fig. 1) into the diagonal prism and tighten the eyepiece thumbscrew (4, Fig. Use the handle to adjust both the horizontal and vertical position of the optical tube.
