Attention! Do not overtighten the screw as you may accidentally damage the screw thread.
5. Loosen the finderscope mounting screws and slide it in the finderscope base. Carefully tighten the screws. The
finderscope should be installed in a way so it points in the same direction as the telescope tube. To align the finderscope,
choose a distant object that is at least 550 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. Check the finderscope to see if the object is
also centered on the crosshairs. Use three adjustment screws to center the finderscope crosshairs on the object.
How to install the mount
Mount without a fork
3a
Remove the altitude lock knob from the mount head.
џ
Place the telescope optical tube on the altazimuth mount so that the hole in the optical tube lines up with the hole in the
џ
mount head.
Insert the altitude lock knob through the mount head and optical tube. Make sure the hole is clear all the way through before
џ
tightening the knob. Secure the altitude lock knob.
Fork mount
3b
Remove the screw from the altitude slow-motion control.
џ
Insert the altitude slow-motion control into the side hole of the fork mount.
џ
Place the telescope tube between fork arms so that holes on the tube match the arm holes. Fasten the telescope tube to the
џ
mount with thumbscrews.
Attach the other end of the altitude slow-motion control to the tube by connecting the screw holes of the altitude slow-motion
џ
control and the telescope tube.
How to work with the telescope
Before starting observations it is very important to install eyepieces and all additional parts correctly.
Focuser. Turn the focusing knob toward the telescope until it will not go farther. Then start turning the knob towards
yourself slowly until the image is clear.
eyepiece is inserted in the focuser. Otherwise, you won't see an image.
Erecting Eyepiece. You will find the erecting eyepiece in the box with the telescope (except for LabZZ TK76). The erecting
eyepiece can be used for lunar and planetary observations and you can also observe a great number of distant terrestrial
objects with it such as buildings, towers, antennas and others!
Attention! The erecting eyepiece should be inserted directly into the focuser, without the diagonal mirror.
Diagonal mirror: Pull out the erecting eyepiece and insert the diagonal mirror into the focuser.
Eyepieces. After the diagonal mirror is inserted into the focuser, insert the eyepiece in it. It's better to start observing using
an eyepiece with low magnification and wide field of view. It's better to start observing using an eyepiece with low
magnification and wide field of view.
Barlow lens. The Barlow Lens is used together with eyepieces to achieve maximum magnification. It expands the cone of the
focused light before it reaches the focal point, so that the telescope's focal length appears longer to the eyepiece. In
addition to increasing magnification, the benefits of using a Barlow lens include improved eye relief, and reduced spherical
aberration of the eyepiece. For this reason, a Barlow plus a lens often outperform a single lens producing the same
magnification. And the best advantage is that a Barlow lens can potentially double the number of eyepieces in your
collection.
How to start observing
CAUTION! Never look at the Sun and the sky around it through a telescope!
Before you start exploring the Cosmos, you should learn to operate the telescope during the day. Use the erecting eyepiece
to observe different terrestrial objects — houses, trees, antennas on the rooftops and many others! This way you will learn to
control the telescope and focus on desired objects. Besides, it's a lot of fun!
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, for example, the Moon. 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!
When working with the telescope, be careful and patient. Don't push it and don't move it from its place. After some training
you will learn to move the telescope tube without losing the object from the sight of the eyepiece.
Attention! Before focusing the view (adjusting its sharpness), make sure that
