• 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 filter or a Herschel wedge. Internal heat build-up inside the telescope can cause these devices
to crack or break, allowing unfiltered sunlight to pass through to the eye.
• Do not leave the telescope unsupervised, either when children are present or adults unfamiliar with the correct operating
procedures of your telescope are present.
SOLAR WARNING
We recommend saving your telescope box so it can be used to store the telescope when it is not in use. Unpack the box
carefully as some parts are small. Use the parts list below to verify that all parts and accessories are present.

Set up your Travel Scope indoors the first time and familiarize yourself with the correct assembly procedure before
attempting it outdoors.
ASSEMBLY
SETTING UP THE TRIPOD
1. The tripod comes preassembled. Stand the tripod upright and
pull the tripod legs outward until each leg is fully extended.
2. To raise the height of the tripod, unlock the tripod leg lock
clamps at the bottom of each tripod leg by opening the clamp
for each section and pulling outward. Once a clamp is unlocked,
pull the tripod leg out as far as it will go, and then close the
leg lock to secure it. Continue doing this for each tripod leg
and each section to raise the height to the level you desire.
3. If you want to raise the tripod height up further, use the central
column locking knob. Turn the locking knob counterclockwise
until loose. Then, pull up on the head of the tripod. Continue
pulling to the height you desire and then tighten the locking
knob. To ensure the stability of the mount, make sure the column
extension knob is tight.

ENGLISH I7
ATTACHING THE TELESCOPE OPTICAL TUBE TO THE TRIPOD
The telescope optical tube attaches to the tripod using the mounting bracket on the bottom of the optical tube and the
mounting platform of the tripod. Before starting, make sure all of the knobs on the tripod are locked.
1. Flip the lever on the side of the tripod head to release the
quick-release mounting plate and lift it out of the tripod head.
2. Screw the quick-release mounting plate to the bottom of the
telescope optical tube.
3. Place the telescope optical tube with the quick-release
plate back into the tripod head and secure it by pushing the
quick-release lever so it is flush against the mount.
MOVING THE TELESCOPE MANUALLY
The Travel Scope is easy to move wherever you want to point it. The up and down (altitude) is controlled by the pan handle.
Unlock the up and down motion by rotating the pan handle counterclockwise, move the telescope up or down as needed and
then rotate the pan handle clockwise to lock it in place. You can adjust how much force it takes to turn the telescope left and
right by adjusting the azimuth tension knob.

8 I ENGLISH
INSTALLING THE DIAGONAL AND EYEPIECE
The Travel Scope uses a 45 degree erect image diagonal that corrects the image to be right side up and oriented
correctly left-to-right which is much easier to use for terrestrial observing. The diagonal can be rotated to any position.
To install the diagonal and eyepiece:
INSTALLING THE FINDERSCOPE
The Travel Scope comes with a small optical finderscope to help
you aim the main scope at a distant target.
To install the finderscope:
1. Locate and remove the two silver thumb nuts on the left side of
the telescope tube.
2. Place the finder bracket over the two exposed threaded shafts.
3. Replace the nuts to hold the finderscope in place.

Objective Lens
1. Loosen the two thumbscrews on the rear on the telescope
optical tube and remove the cap covering the focuser.
2. Remove the caps from both ends of the diagonal and insert
the chrome barrel of the diagonal inside the focuser of the
telescope optical tube. Secure the two thumbscrews to hold it
in place.
3. Loosen the set screws on the side of the diagonal and insert
the chrome barrel of the eyepiece into the diagonal. Secure the
thumbscrews to hold the eyepiece in place.

ENGLISH I9
FOCUSING
To focus your TravelScope turn the focus knob located near the rear of the telescope while looking through the telescope’s
eyepiece. If you wear glasses, you may want to remove them when observing with an eyepiece attached to the telescope.
However, if you have astigmatism, corrective lenses should be worn at all times. You will need to refocus the telescope each
time you change eyepieces or view targets at different distances from you.
ALIGNING THE FINDERSCOPE
In order to use your finderscope, you need to ensure it is pointing in the same direction as your main telescope. It is
recommended that you do this during the day. To do this:
1. Take the scope outside, remove the lens cap, and locate a distant daytime object such as a signpost, light pole, radio
antenna, etc. We recommend an object at least a quarter of a mile away but if this is not possible, use an object as far
away as you can.
2. Center this object in the main telescope using a low power (20 mm) eyepiece in the main telescope.
3. Look through the eyepiece of the finderscope and take notice of the position of the same object.
4. Without moving the main telescope, turn the adjustment thumbscrews located around the finderscope bracket until the
crosshairs of the finderscope are centered on the object chosen with the main telescope.
Your telescope and finderscope are now aligned. To aim the main telescope, grab the mount’s pan handle and loosen the
altitude lock. Look through your finderscope until the crosshairs are on the target you want to view and lock the altitude
lock to hold the scope in place. Now look through your low power eyepiece in the main telescope and the target should be
visible. To zoom in on the target, change to your higher power eyepiece and refocus the telescope using the focus knobs.
Note: Objects viewed through a finderscope are upside down and backwards, which is normal.

10 I ENGLISH
When using any optical instrument, there are a few things to remember to ensure you get the best possible image.
• Never look through window glass. Glass found in household windows is optically imperfect, and as a result, may vary in
thickness from one part of a window to the next. This inconsistency can and will affect the ability to focus your telescope. In
most cases you will not be able to achieve a truly sharp image, while in some cases you may actually see a double image.
• Never look across or over objects that are producing heat waves. This includes asphalt parking lots on hot summer days or
building rooftops.
• Hazy skies, fog, and mist can also make it difficult to focus when viewing terrestrially. The amount of detail seen under these
conditions is greatly reduced.
Note: Your telescope was designed for terrestrial observation. Knowing how to use it for this purpose has been described
already as it is quite simple and straightforward. Your telescope can also be used for casual astronomical observing
which will be discussed in the next sections.
