ZOOM and FOCUS:

1) Your telescope is equipped with a 30X-90X zoom eyepiece* (6). To change the

magnification power, gently turn the rubber zoom ring (7) on the eyepiece. The
magnification power is indicated on the side of the eyepiece.
* Some models may be equipped with zoom eyepieces with a 15X-45X power
range or a 20X-60X power range.

2) Set the eyepiece to its lowest magnification.

3) Turn the rubberized focusing knob (8) until you see the clearest image. The focus

adjustment actually moves the rear mirror inside your telescope. This precision
adjustment gives you the ability to make extremely fine focus adjustments.

4) To see your subject at a higher magnification, turn the zoom ring (7) on the

eyepiece. You will have to re-adjust the focusing knob (8).

5) Note that as the zoom power increases, the brightness of the image decreases.

This is quite normal. To observe in low light situations you will find the lower
zoom powers perform better.

USING YOUR TELESCOPE FOR ASTRONOMICAL VIEWING

1) Take your telescope outside. We do not recommend viewing objects through a

window. Your view can be distorted by reflections in the glass of a closed window or
by air currents of differing temperatures passing through an open window.

2) Allow your telescope to adjust to the outside temperature. Your telescope will

perform much better if the temperature of the lenses and the air inside the tube are
the same as the outside temperature. We recommend that you allow 30 minutes to
equalize the temperatures when the difference in temperature difference is extreme.
