Dec. Balancing

1. Tighten the R.A. lock knob when the counterweight rod is horizontal to the ground.

2. While holding the telescope with one hand, loosen the Dec. lock knob with the other.

3. Loosen the telescope tube rings and slide the telescope forward or backward until it is balanced even when you release the

telescope tube. Tighten the tube rings the Dec. lock knob.

The equatorial mount allows for compensating the rotation of Earth around its axis and easily tracking celestial objects during

observations. To achieve this, the R.A. axis has to be aligned to the rotation axis of Earth. This process is known as polar

alignment.

Look north and nd Polaris. As it is located within 1° of the rotation axis of Earth (North Celestial Pole), you will be aligning your

telescope to this star.

1. Loosen one of the adjustment screws and tighten the other until your latitude is shown on the latitude scale by the indicator

pin (while doing this the mount ascend or descend. You can look up the latitude of your location on a map.

2. Loosen the Dec. lock knob and rotate the telescope tube until it is parallel to the R.A. axis. Tighten the lock knob. Doing this

will make it easier to aim your telescope at Polaris.

3. Loosen the azimuth locking knob and rotate the mount until both the tube and the R.A. axis are pointed at Polaris. Retighten

the azimuth locking knob. If you cannot nd Polaris, try pointing the telescope and the R.A. axis due north.

Upon doing this, no further adjustments in the azimuth and latitude of the mount should be made during the observing session,

nor should you move the tripod. Only movements in R.A. and Dec. axes should be made in order to keep the telescope aligned.

Now, to aim the telescope at an object (the Moon, Jupiter, Saturn, etc.) loosen the R.A. & Dec. lock knobs, point the telescope

tube toward the object, and retighten the lock knobs. Look at the object through the nder and aim the telescope precisely

with slow-motion controls. Make sure the red dot is pointing at the object. Start observing by using the 25mm eyepiece and

focus your view. To study the details of the Moon or planets, just follow this simple procedure.

1. With a low power eyepiece, make sure that the observed object is directly in the center of the eyepiece crosshairs.

2. Remove the eyepiece and replace it with a high power one. You can also use a Barlow lens to achieve maximum power. To do

that, rst insert the Barlow lens in the focuser and then place an eyepiece into the receiving end of your Barlow lens.
