SOLAR WARNING

Never look directly at the Sun with the naked eye or with a telescope unless you have the proper solar filter. Permanent and irreversible eye damage may result.
Never use your telescope to project an image of the Sun onto any surface. Internal heat build-up can damage the telescope and any accessories attached to it.
Never use an eyepiece solar fi lter or a Herschel wedge. Internal heat build-up inside the telescope can cause these devices to crack or break, allowing unfi ltered sunlight to pass through to the eye.
Do not leave the telescope unsupervised, especially when children or adults unfamiliar with the correct operating procedures of your telescope are present.

ASSEMBLING YOUR TELESCOPE

THE MOUNT

The Inspire mount and tripod come fully assembled, so setting it
up is easy.

1. Remove the tripod and mount from the box.

2. Loosen the hand knobs at the bottom of each leg and extend

the inner section of the leg to the desired length. Tighten the
knobs to secure the legs, being careful not to over tighten.

3. Stand the tripod upright and pull the tripod legs apart until the
folding accessory tray snaps into place.

4. Line up the t abs on the spring-loaded acce ssory tray locking
knob with the notches in the accessory tray and press
downward. Turn the locking knob clockwise about 20 degrees
to fully lock the tray in place.

5. Turn the accessory tray tension knob clockwise until it stops.

Do not over tighten.

NOTE: When closing the tripod at the end of the observing session, be sure to fi rst loosen the tension

knob all the way, then loosen the locking knob by turning it counterclockwise until the spring
pops the locking knob upward. Grab the knob and lift upward and the tripod will fold up.

THE TELESCOPE TUBE

To attach the telescope tube to your tripod and mount:

1. Loosen the two tube mounting bolts on the side of the dovetail

saddle on top of the mount.

2. Locate the dovetail bar on the bottom of the telescope tube
and slide it into the saddle. The eyepiece end of the telescope
tube should point in the same direction as the panning handle
on the mount.

3. When the dovetail is centered in the saddle, tighten the two
tube mounting bolts, starting with the larger one fi rst. Finish by
tightening the smaller one.

4. Remove the lens cap when you are ready to observe by simply
pulling it off the lens shade.

THE ERECT DIAGONAL

The Inspire telescopes come with a 90° erect image diagonal.
This accessory uses a prism to bend the light at a 90° angle,
providing a more comfortable viewing position. It also gives you
a 100% correctly oriented image allowing you to easily use this
telescope for daytime terrestrial observing.

To install the erect image diagonal:

1. Remove the caps from both sides of the diagonal.

2. Loosen the setscrews on the back of the telescope focuser and

pull out the small dust cap.

3. Insert the smaller tube on the diagonal into the back of the
focuser and secure it by tightening the setscrews.

THE EYEPIECES

Your Inspire telescope comes with two eyepieces, a low power
(20 mm eyepiece) and a higher power eyepiece (10 mm eyepiece).
Whenever you set up your telescope, always start with the 20
mm eyepiece. Once you have your target centered in the 20 mm
eyepiece, you can switch to your higher power 10 mm eyepiece to
increase magnifi cation and get a more detailed view.

To install an eyepiece:

1. Loosen the setscrews on the open end of the erect im age diagonal.

2. Insert the silver barrel of the 20 mm eyepiece into the diagonal.

3. Tighten the setscrews to secure the eyepiece.

4. To see the sharpest image possible, you need to adjust the

telescope’s focus. Look through the eyepiece and slowly turn
the focusing knobs until you see the sharpest image possible.

NOTE: You should always adjust focus whenever you change eyepieces or if another person views

through the telescope as the focus may be different for each individual.
