– 6 – INTRODUCTION The Meade 1 14 EQ-DS is an easy-to-operate, high performance 4.5" (1 14mm) reflecting telescope, intended for astronomical observing. Equipped with a deluxe equatorial mount and aluminum tripod, the telescope’s motion is continuously adjustable for tracking celestial objects. Y our telescope comes to you ready for adve[...]

– 7 – • Remove the viewfinder bracket mounting nuts from the viewfinder bracket mounting bolts ( 16 ) that protrude from the optical tube ( 12 ), near the focuser ( 17 ). Place the viewfinder bracket ’ s mounting holes (located at the base of the bracket) over the mounting bolts, so that the bracket is oriented as shown in Fig. 1 . Replace [...]

– 8 – • Check this alignment on a celestial object, such as a bright star or the Moon, and make any refinements necessary , using the method outlined above. With this alignment performed, objects first located in the wide-field viewfinder will also be centered in the main telescope ’ s field of view . ( Note: The viewfinder presents an imag[...]

South of the celestial equator are indicated with a minus ( – ) sign ( e.g. , the Dec. of the South celestial pole is – 90 ° ). Any point on the celestial equator (such as the the constellations of Orion, V irgo, and Aquarius) is said to have a Declination of zero, shown as 0 ° 0' 0." With all celestial objects therefore capable of [...]

– 10 – • T o center an object in the main telescope, loosen the telescope ’ s R.A. lock ( 22, Fig. 1c ) and Dec. lock ( 23, Fig. 1c ). The telescope can now turn freely on its axes. Use the aligned viewfinder to first sight-in on the object you wish to observe; with the object centered on the viewfinder ’ s crosshairs, re-tighten the R.A.[...]

– 11 – • The Moon: A veritable treasury of craters, mountain ranges and fault lines. The best contrast for viewing the Moon is during its crescent phase. The contrast during the full Moon phase is low due to the angle of illumination. • Deep-Space: Nebulae, galaxies, multiple star systems, star clusters – hundreds of such objects are visi[...]

– 12 – MAINTENANCE Cleaning As with any quality instrument, lens or mirror surfaces should be cleaned as infrequently as possible. Front surface aluminized mirrors, in particular , should be cleaned only when absolutely necessary . In all cases avoid touching any mirror surface. A little dust on the surface of a mirror or lens causes negligible[...]

Then, if necessary , make adjustments to these 3 Phillips-head screws to refine the tilt-angle of the diagonal mirror until the entire primary mirror can be seen centered within the diagonal mirror reflection. When the diagonal mirror is correctly aligned, it will look like Fig. 9 . (Note: the primary mirror is shown out of ali[...]
