Finderscope
A finderscope is a very useful accessory that simplifies the search for objects through the sky.
Using it, you can easily locate desired objects and keep them in the center of the field of view.
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. It is
important to assemble it correctly – 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
A Barlow lens is a useful accessory that increases the focal length of a telescope and thereby
increases magnification with every eyepiece used. 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. The
image usually has to be finely refocused over time due to small variations caused by temperature
changes, flexures, etc. 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, antennas on the rooftops and many
others! This way you will learn to control the telescope and focus on desired objects.
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.
