SETTING UP THE TRIPOD

The tripod comes preassembled, so that the setup is very easy.
Stand the tripod upright and pull the tripod legs outward until each leg is fully extended (Figure 3).
You can raise the tripod legs to the height you desire. At the lowest level , he height is about 16” (41 cm) and extends to about 49” (125 cm).
To raise the height of the tripod, you unlock the tripod leg lock clamps at the bottom of each tripod leg (Figure 4) by opening the clamp for each section by pulling outward. Once a clamp is unlocked, then 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. A fully extended tripod looks similar to the image in Figure 5. With all the legs raised up on all sections, the height will be about 42” (107 cm).
If you want to raise the tripod height up further, you must use the central column locking knob, which is the knob located at the bottom left in Figure 6. Turn the locking knob counterclockwise until loose. Then, pull up on the head of the tripod,d and the central column will move up. Continue pulling to the height you desire and then tighten the locking knob. When the central column is raised up as far as it will go, then the maximum height possible is achieved – 49” (125 cm).

ATTACHING THE TELESCOPE TUBE TO THE TRIPOD

The telescope optical tube attaches to the tripod by 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.

Remove the protective paper covering the optical tube.
Loosen the top right knob (Figure 7) by turning it counterclockwise. This allows you to tilt the tripod platform up 90° as shown in Figure 8. After tilting the platform up, tighten the knob to secure it in place.
Figure 9 shows the bottom of the optical tube, the tripod platform, and where they will attach to each other.
Under the center of the tripod platform, you will see a knob (Figure 9) that contains a ¼ x 20 screw to attach the platform to the telescope optical tube.
Align the ¼ x 20 screw with the threaded hole on the telescope’s mounting bracket (NOTE: there are 2 threaded holes on the Travel Scope 70 , and it doesn’t matter which one you use). Hold the optical tube with one hand while threading the screw clockwise until tight with the other hand. Now the assembly will look like Figure 10. Hold the optical tube with one hand while threading the screw clockwise until tight with the other hand. Now the assembly will look like Figure 10.
Lastly, loosen the knob for the tripod platform and lower the platform down to the level position. Then, tighten the knob securely.

USING THE SMARTPHONE ADAPTER

Use the phone clamp knob to open the phone holder so that your phone fits inside. Tighten it to secure your phone in place.
Turn on the phone and open your camera app. Make sure the flash is turned off.
Loosen the knob on the bottom of the adapter that secures the phone clamp to the eyepiece clamp. Slide the phone clamp up and down and rotate it left and right until your camera is looking down through the eyepiece of the telescope. Tighten the knob on the bottom of the adapter to secure it in place.
Use the telescope’s focuser to adjust the focus of your camera. Snap the image using your app.

TELESCOPE MAINTENANCE

While your telescope requires little maintenance, there are a few things to remember that will ensure your telescope performs at its best.

CARE AND CLEANING OF THE OPTICS

Occasionally, dust and/or moisture may build up on the objective lens of your telescope. Special care should be taken when cleaning any instrument so as not to damage the optics.
If dust has built up on the optics, remove it with a brush (made of camel’s hair) or a can of pressurized air. Spray at an angle to the glass surface for approximately two to four seconds. Then, use an optical cleaning solution and white tissue paper to remove any remaining debris. Apply the solution to the tissue and then apply the tissue paper to the optics. Low-pressure strokes should go from the center of the lens (or mirror) to the outer portion. Do NOT rub in circles!
You can use a commercially made lens cleaner or mix your own. A good cleaning solution is isopropyl alcohol mixed with distilled water. The solution should be 60% isopropyl alcohol and 40% distilled water. Or, liquid dish soap diluted with water (a couple of drops per one quart of water) can be used.
Occasionally, you may experience dew build-up on the optics of your telescope during an observing session. If you want to continue observing, the dew must be removed, either with a hair dryer (on low setting) or by pointing the telescope at the ground until the dew has evaporated.
If moisture condenses on the inside of the optics, remove the accessories from the telescope. Place the telescope in a dust-free environment and point it down. This will remove the moisture from the telescope tube.
To minimize the need to clean your telescope, replace all lens covers once you have finished using it. Since the cells are NOT sealed, the covers should be placed over the openings when not in use. This will prevent contaminants from entering the optical tube.
Internal adjustments and cleaning should be done only by the Celestron repair department. If your telescope needs internal cleaning, please call the factory for a return authorization number and price quote.
