User manual BUSHNELL DEEP SPACE 78-9519

[. . . ] Locate the long bolts and washers from the hardware pack. Position the mount over the Tripod Leg as shown (fig. and align the holes in the Tripod Leg with the holes in the mount. Insert the bolts through the holes at the top of a Tripod Leg (9). [. . . ] Make sure that the shaft is securely locked into mount. Locate Eyepiece (17) and Diagonal Mirror (16). Carefully place Eyepiece into Diagonal Mirror as shown (fig. b) 17 16 · 15 fig b. Your Bushnell telescope is now ready to be used. To obtain the fullest enjoyment from your telescope, please refer to the additional information below. III. UNDERSTANDING THE EQUATORIAL MOUNT The equatorial mount is designed to move in any direction. It can be set to allow manual controls to track the movements of celestial bodies across the sky. This is referred to as diurnal movement; movement of celestial bodies in the direction opposite to that of the earth's rotation and is around the earth's axis. By aligning the telescope's polar axis at celestial North, you will place the telescope in parallel with the earth's axis and thus be able to locate stars in the sky based on star atlas information. To compensate for your position on earth, the polar axis is set in one of three ways: · Set up the telescope at night. Loosen the Declination Lock Knob (3) and rotate the telescope around the declination axis until the arrow on the declination scale points to 90 degrees. The telescope is now roughly in parallel with the polar axis. Loosen the Azimuth Lock Knob (8) and turn the telescope until the objective end faces due north. This can be done by approximating the location of the pole star (Polaris or North Star) or by the use of a compass. True North is then found by directing the telescope at Polaris, as magnetic North is slightly away from true North. Look up the latitude of your area in any geographical atlas. Loosen the Altitude Lock Knob (7) and set the latitude scale to the correct latitude for your area. You will probably notice that Polaris is not dead center in the finderscope's field of view. This is probably because your telescope is not absolutely level with the ground. Loosen the Azimuth Lock Knob (8) again and turn the telescope so that it is directly aimed at Polaris. Tighten both the Azimuth Lock Knob and Altitude Lock Knob. Polaris is 1 degree of the North celestial pole. [. . . ] Now, objects located first with the Finderscope (20) will be centered in the field of view of the main telescope. 3.
