– 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.
– 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.
– 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 .
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.
– 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.
– 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.
– 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.
