THE FOCUS MICROMETER

Your Inspire telescope tubes come with a focus micrometer that allows you to repeatedly dial in focus for objects at different distances

quickly and easily before you even move the scope to the target. The window on the side of the focuser allows you to see a numbered

scale displaying a number from 0 to 10. The 0 on the scale represents the closest point at which you can achieve focus using the

standard eyepieces and diagonal. The 10 represents inﬁ nity focus. While astronomical objects will generally be at inﬁ nity focus, you may

wish to use the telescope to view terrestrial objects, such as bird nests or other targets at ﬁ xed distances. Once you have focused in a

terrestrial target, make a note of the number shown on the scale. The next time you observe that same target from the same observing

location, you can quickly dial the focuser to that same number and the image should be in focus when you view through the eyepiece.

MOVING THE TELESCOPE

The Inspire altazimuth mount is simple to use. To move the scope

left and right, loosen the azimuth tension knob at the base of the

mount between two of the tripod legs. Grab the knob at the end

of the panning handle and move the scope to the desired location.

You can adjust the tension of the left and right motion by adjusting

the azimuth tension knob.

To move the scope up and down, loosen the altitude clutch by turning

the knob at the end of the panning handle counter-clockwise. Move the

handle up or down as required and turn the knob clockwise to lock

the scope on target.

ALIGNING THE STARPOINTER PRO FINDERSCOPE

The StarPointer Pro ﬁ nderscope helps you aim your telescope by looking through its round glass window and covering your target with the

red reticle projected in the window. The ﬁ rst time you assemble your telescope, you will need to align the ﬁ nderscope with the main optics

of the telescope. Although this step can be done at night, it is signiﬁ cantly easier during the day. Once you have completed the ﬁ nderscope

alignment, you should not have to repeat this step unless the ﬁ nderscope is bumped or the telescope is dropped.

1. Take the telescope outside during the day. Using your naked eye, ﬁ nd an easily recognizable object, such as a streetlight, car license plate,

or tall tree. The object should be as far away as possible, but at least a quarter mile away.

2. Remove the main dust cover from the telescope and make sure your 20 mm eyepiece is installed.

3. Move the telescope left and right or up and down so that it is roughly pointing toward the object you chose in step 1.

4. Look through the telescope's eyepiece and manually move the telescope until the object you chose lies in the center of the view. If the

image is blurry, gently turn the focus knobs until it comes into sharp focus.

5. Once the object is centered in your 20 mm eyepiece, turn on the ﬁ nderscope by turning the on/off/brightness switch knob on the bottom

of the unit as far as it will go.

6. With your head positioned about a foot behind the ﬁ nder, look through the round window and locate the red reticle. It will probably be

close to, but not on top of, the object you see when you are looking through the 20 mm eyepiece.

7. Without moving the telescope, use the two adjustment knobs on the side and underneath the ﬁ nderscope. One controls the left-right

motion of the reticle, while the other controls the up-down motion. Adjust both until the reticle appears over the same object you are

observing in the 20 mm eyepiece.

Now choose some other distant targets to practice aiming your telescope. Look through the StarPointer Pro ﬁ nderscope window and place

the red reticle over the target you are trying to view and verify that it appears in the eyepiece of the scope.

With your ﬁ nderscope aligned, your telescope is fully assembled and you are ready to observe!

NOTE:

Be sure to turn off the StarPointer Pro ﬁ nderscope when not in use to conserve battery power.
