– 6 – INTRODUCTION The Jupiter 1 14 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 – • Release the latitude lock ( 9 ) of the equatorial mount, and tilt the polar axis ( 10 ) of the telescope to roughly a 45 ° angle by turning the latitude adjustment knob ( 11 ). With the polar axis thus tilted, firmly re-tighten the latitude lock.
– 8 – • Unlock the R.A. lock ( 22, Fig. 1 ) and the Dec. lock ( 23, Fig. 1 ) so that the telescope turns freely on both axes. Then point the main telescope at some well-defined land object (e.g. the top of a telephone pole) at least 200 yards distant, and re-lock the R.
the celestial equator (which passes, for example, through the constellations Orion, Virgo and Aquarius) is specified as having 0 ° 0'0" Declination. The Declination of the star Polaris, located very near the North Celestial Pole, is +89.2 ° .
– 10 – USING THE TELESCOPE With the telescope assembled, balanced and polar aligned as described above, you are ready to begin observations. Decide on an easy-to-find object such as the Moon, if it is visible, or a bright star to become accustomed to the functions and operations of the telescope.
– 11 – • Cloud belts across the surface of the planet Jupiter . • The 4 major satellites of Jupiter , visible in rotation about the planet, with the satellite positions changing each night. • Saturn and its famous ring system, as well as several satellites of Saturn, much fainter than the major satellites of Jupiter .
– 12 – Assorted eyepieces are available both to increase and decrease the operating eyepiece power of the telescope. If the Jupiter 1 14 EQ-D is used on a regular basis, a selection of four to five eyepieces is recommended. For example, an eyepiece assortment of focal lengths 40mm, 25mm (Included as standard equipment), 12.
– 13 – T o inspect the view of the mirror collimation, look down the focuser drawtube with the eyepiece removed. The edge of the focuser drawtube ( 1, Fig. 7 ), will frame the reflections of the primary mirror with the 3 mirror clips ( 2, Fig. 7 ), the diagonal mirror ( 3, Fig.
– 14 – • As you make adjustments to the primary mirror tilt screws ( 3, Fig. 6 ), you will notice that the out- of-focus star disk image will move across the eyepiece field. Choose one of the 3 primary mirror tilt screws and slightly move the shadow to the center of the disk.
