1. Stand the tripod legs upright and spread the legs out as far as they will go. Keep the tripod legs at their shortest (fully retracted) length, for now; you can extend them to a more desirable length later , after the scope is fully assembled. 2. Place the base of the equatorial mount onto the tripod head.
the mounting plate and rethread into the tube rings. Note that the side of the mounting plate with the central “groove” will be facing up. Use the small wrench to secure the tube rings to the mounting plate. 10. Loosen the black mounting plate securing knob as well as the metal safety thumbscrew on the top of the equatorial mount.

achieved by focusing the finder scope on a bright star . Once the image appears sharp, retighten the locking ring behind the objective lens cell. The finder scope’s focus should not need to be adjusted again.
8 knob. But first the R.A. axis of the mount must be aligned with the Earth’ s rotational (polar) axis—a process called polar alignment. Polar Alignment For Northern Hemisphere observers, approximate polar align - ment is achieved by pointing the mount’s right ascension axis at the North Star , or Polaris.
9 directly from your observing site, consult a compass and rotate the tripod so the telescope points north. There is a label bearing a large “N” at the base of the equatorial mount (Figure 8). It should be facing north. The equatorial mount is now polar aligned for casual observ - ing.
2. Loosen the Dec. lock lever and rotate the optical tube on the declination axis so that the tube is at a 90° to the right ascension axis (Figure 10). This is so you can view through the mount with the polar axis finder . T ighten the Dec. lock lever .

12 the scope in declination so it points to where you want it near the horizon. T o point the telescope directly south, the counterweight shaft should again be horizontal. Then you simply rotate the scope on the declination axis until it points in the south direction.
tion outside to cooler air (or vice-versa), a telescope needs time to cool to the outdoor temperature. The bigger the instru - ment and the larger the temperature change, the more time will be needed. Allow at least 30 minutes for your SkyView Pro 120 EQ to equilibrate.
14 Important Note: Do not look at the Sun with any optical instrument without a professionally made solar filter , or permanent eye damage could result.
15 the stars you are centering in the eyepiece. Remember , the finder scope (and main telescope eyepiece, for that matter) gives an inverted image, so you must keep this in mind when starhopping from star to star . 8. Astrophotography Several dif ferent types of astrophotography can be success- fully attempted with the SkyView Pro 120 EQ.
