INTRODUCTION The Meade 1 14ST EQ-D 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 – the counterweight lock ( 7, Fig. 1a ) of the counterweight. Note : If the counterweight ever slips, the secured threaded safety washer/screw ( 8, Fig. 1a ) will not let the weight slide entirely off the counterweight shaft. Be certain that this safety washer/screw is alwa ys in place .
– 8 – 2. Loosen the counterweight’s lock ( 7, Fig. 1a ) and slide the counterweight ( 5, Fig. 1a ) along the shaft until the telescope remains in any given position without tending to drift up or down the polar axis. Then retighten the counterweight lock.
( – ) 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, Virgo, and Aquarius) is said to have a Declination of zero, shown as 0 ° 0' 0.
– 10 – • Always start an observation with a low power eyepiece (the MA 25mm eyepiece); get the object well- centered in the field of view and sharply focused.
– 11 – from a star chart, and move the telescope in R.A. and Declination until the setting circles read the R.A. and Dec. of the object you are attempting to locate. If the above procedure has been carefully performed, the faint object will now be in the field of a low power eyepiece.
– 12 – Collimation (Alignment) of the Optics All Meade 1 14ST EQ-D telescopes are optically aligned at the factory prior to shipment. It is unlikely that you will need to align, or collimate, the optics after receipt of the instrument.
– 13 – d. Star testing the collimation With the collimation performed, you will want to test the accuracy of the alignment on a star . Use the MA 25mm eyepiece and point the telescope at a moderately bright (second or third magnitude) star , then center the star image in the telescope ’ s field-of-view .
