providing a more comfortable viewing position Because a star diagonal gives you a 100% correctly oriented image, you
can easily use the telescope for daytime terrestrial observing

1 . Remove the caps from both sides of the diagonal
2 . Loosen the setscrews on the back of the focuser and
pull out the small dust cap

the focuser and secure it by tightening the setscrews
You can adjust the angle of the star diagonal to any
desired direction before tightening the screws
Your telescope comes with two eyepieces The 20mm which will give low magnification with a moderately wide field of
view The 10mm will give you higher magnification, but a narrower field of view Additional eyepieces can be purchased
to increase or decrease the magnification to your desired level When first locating an object, it is best to use the 20mm
eyepiece, then, once the object is centered, change to the 10mm eyepiece to "zoom in" on it
To install the eyepiece:
1 . Loosen the setscrews on the open end of the star
diagonal
2 . Insert the silver barrel of the 20mm eyepiece into the
star diagonal
3 . Tighten the setscrews to secure the eyepiece in place
4 . To see the sharpest image possible, focus by looking
through the eyepiece and slowly turning the focusing
knobs until the image comes into sharp focus
