– 7 – • Release the latitude lock (9) of the equatorial mount, and tilt the polar axis (10) of the telescope toroughly a 45° angle by turning the latitude adjustment knob (11). With the polar axis thus tilted, firmlyre-tighten the latitude lock. • Loosen the lock knobs (15) of the cradle rings (14) ...

(which passes, for example, through the constellations Orion, Virgo and Aquarius) is specified as having0°0'0" Declination. The Declination of the star Polaris, located very near the North Celestial Pole, is +89.2°. The celestial equivalent to Earth longitude is called “Right Ascension,” or “R.A...

– 10 – • To center an object in the main telescope, loosen the telescope’s R.A. lock (22) and Dec. lock (23). Thetelescope can now turn freely on its axes. Use the aligned viewfinder to first sight-in on the object you wishto observe; with the object centered on the viewfinder’s crosshairs, re-tight...

– 11 – • The Moon: A veritable treasury of craters, mountain ranges and fault lines. The best contrast for viewingthe Moon is during its crescent phase. The contrast during the full Moon phase is low due to the angleof illumination. • Deep-Space: Nebulae, galaxies, multiple star systems, star cluste...
