CAUTION! Never look directly at the Sun – even for an instant – through your telescope or finderscope without a professionally made solar filter that completely covers the front of the instrument, or permanent eye damage may result. To avoid damage to the internal parts of your telescope, make sure the front end of the finderscope is covered with aluminum foil or another non-transparent material. Children should use the telescope under adult supervision only.      

All parts of the telescope will arrive in one box. Be careful when unpacking it. Keep the original shipping package; you will require it if you need to send the telescope to the service center. Make sure all the parts are present in the packaging. Be sure to check the box carefully, as some parts are small. No tools are needed other than those provided. All screws should be tightened securely to eliminate flexing and wobbling, but be careful not to overtighten them, as that may strip the threads. During assembly (and anytime, for that matter), do not touch the surfaces of the optical elements with your fingers. The optical surfaces have delicate coatings on them that can easily be damaged if touched. Never remove lenses from their housing, or the product warranty will be null and void.        

Telescope assembly (2)

  1. Gently pull the aluminum tripod legs apart as far as they will go until the center leg braces sit flat, in a horizontal position.
  2. The telescope tube has a mounting tab (1) on its underside. Place this tab into the slot on the tripod top.
  3. Tighten the knurled knob (2) on the tripod head to attach the tube onto the tripod.
  4. Screw the control arm (3) into the threaded socket at the rear of the mount.
  5. Insert the diagonal mirror into the end of the telescope tube.
  6. Insert the eyepiece into the diagonal mirror.
  7. Remove the dust cap from the front end of the telescope tube.
  8. Your telescope is now ready for use.

Finderscope

Secure the finderscope on the telescope tube. To do that, you need to align the base of the finderscope with a fixing point on the telescope tube and secure it with the supplied fastener. The telescope tube and the finderscope have to ‘look’ in one direction and be strictly parallel to
each other.

To align the finderscope, choose a distant object that is at least 300 yards (500 meters) away and point the telescope at the object. Adjust the telescope so that the object is in the center of the view in your eyepiece.

Using a Barlow lens (3)

Insert the diagonal mirror (1) into the focuser, then insert the Barlow lens (2) into the diagonal mirror, and, finally, install the eyepiece (3) in the Barlow lens.

Focusing

Slowly rotate the focus knobs one way or the other until the image in the eyepiece is sharp. Refocusing is almost always necessary when you change an eyepiece, add or remove a Barlow lens.

How to start observing

Before you start exploring the Cosmos, you should learn to operate the telescope during the day. First, observe different terrestrial objects – houses, trees and many others!

Attention: The telescope should be used in a place protected from the wind. When you get to observing the Moon, planets and stars at night, remember to choose locations away from street lamps, car lights and window lights. Try to observe on nights when the stars shine bright and evenly.

Point the telescope at the desired object. Looking through the finderscope, slowly move the tube until the object is in the center. Now look through the eyepiece and you will see the image of the object magnified many times!

Solar filter (Levenhuk Skyline Travel Sun models)

Attach the solar filter available in the kit to the far end of the telescope tube. The filter must not only cover the objective lens fully, but also fit the telescope’s tube snugly. It is recommended that you also secure the filter on the optical tube with adhesive tape to prevent the filter from
accidentally sliding off during observations.

Care and maintenance

Never, under any circumstances, look directly at the Sun through this device without a special filter, or look at another bright source of light or at a laser, as this may cause PERMANENT RETINAL DAMAGE and may lead to BLINDNESS. Take necessary precautions when using the device with children or others who have not read or who do not fully understand these instructions. Do not try to disassemble the device on your own for any reason. For repairs and cleaning of any kind, please contact your local specialized service center. Protect the device from sudden impact and excessive mechanical force. Do not touch the optical surfaces with your fingers. To clean the telescope exterior, use only special cleaning wipes and special optics cleaning tools from Levenhuk. Seek medical advice immediately if a small part or a battery is swallowed. Children should use the telescope under adult supervision only.
