Page 4: Tripod Set Up
TRIPOD SET UP ASSEMBLING THE TRIPOD LEGS (Fig.1) Fig. 1 Fig. 2. 1) Slowly loosen the height adjustment clamp and gently pull out the lower section of each tripod leg. Tighten the clamps to hold the legs in place. 2) Spread the tripod legs apart to stand the tripod upright. 3) Place a carpenter's level or bubble level on the top of the tripod legs. -

TELESCOPE ASSEMBLY Fig. 8 ATTACHING THE TELESCOPE MAIN TUBE TO THE TUBE RINGS (Fig.8) 1) Remove the telescope tube from the paper covering. 2) Find the center of balance of the telescope tube. Place this in between the two tube rings. Close the hinges around the telescope and fasten securely by tightening the thumb nuts. - Page 6 These fixed magnification scopes mounted on the optical tube are very useful accessories. When they are correctly aligned with the Fig.a telescope, objects can be quickly located and brought to the centre of the field. Alignment is best done outdoors in daylight when it's easier to locate objects.

Page 7: Using The Hand Control
The EQ6 mount has controls for both conventional altitude Fig.c (up-down) and azimuthal (left-right) directions of motion. Use the altitude adjustment T-bolts for altitude adjustments. These Altitude allow fine-adjustment for setting the mount to your local adjustment latitude. The azimuthal axis is changed by the two azimuth adjustment knobs located near the tripod head. -
Page 8: Focusing
A Barlow is a negative lens which increases the magnifying power of an eyepiece, while reducing the field of view. It Fig.e expands the cone of the focussed light before it reaches the Eyepiece focal point, so that the telescope's focal length appears Barlow longer to the eyepiece. -
Page 9: The Polarscope
Big Dipper Alligning your telescope to Polaris Fig.g-1 Unlock the DEC lock knob and rotate the telescope tube until the pointer on the setting circle reads 90˚. Retighten the DEC lock knob. Move the tripod so that the equatorial mount faces north and the R.A. - Page 10 Fig.h-1 Locate Polaris and place it in the center of the Polarscope by adjusting the Altitude and Azimuth of the mount. Place Polaris directly under the cross in the center of the reticle (Fig.h-1). Rotate the mount one half turn about the R.A. axis. Polaris should remain under the cross in the center of the reticle.
- Page 11 The polar alignment is now complete. This should get the Place Polaris here mount's R.A. axis within 5 arc-minutes of the celestial pole. Fig.h-4 Due to its proper motion, Polaris can be seen to move with respect to the Pole from year to year. The tick marks in the Point this line at Polarscope can be used to compensate for this motion.

Page 12: Setting Circles
The quickest way to find objects is to learn the Constellations and use the finderscope, but if the object is too faint you may Fig.i want to use setting circles on an equatorial mount. Setting circles enable you to locate celestial objects whose celestial co-ordinates have been determined from star charts. - Page 13 Calculating the magnification (power) The magnification produced by a telescope is determined by the focal length of the eyepiece that is used with it. To determine a magnification for your telescope, divide its focal length by the focal length of the eyepieces you are going to use.

Page 14: Sky Conditions
Sky conditions are usually defined by two atmospheric characteristics, seeing, or the steadiness of the air, and transparency, light scattering due to the amount of water vapour and particulate material in the air. When you observe the Moon and the planets, and they appear as though water is running over them, you probably have bad "seeing"... - Page 15 Fig.j Collimation is the process of aligning the mirrors of your telescope so that they work in concert with each other to deliver properly focused light to your eyepiece. By observing out-of-focus star images, you can test whether your telescope's optics are aligned. Place a star in the centre of the field of view and move the focuser so that the image is slightly out of focus.
- Page 16 Aligning the Primary Mirror There are flat headed screws and 3 thumbscrews at Fig.j-5 the back of your telescope, the flat headed screws are the locking screws and the thumbscrews are the Locking adjusting screws (Fig.j-5). Loosen the flat headed screw screws by a few turns.
