Which eyepiece is right?
First of all, it is important that you always choose
an eyepiece with the highest focal width for the
beginning of you observation. Afterwards, you
can gradually move to eyepieces with smaller
focal widths. The focal length is indicated in
millimeters, and is written on each eyepiece.
In general, the following is true: The larger
the focal width of an eyepiece, the smaller the
magnification! There is a simple formula for
calculating the magnification:
Focal length of the telescope tube: Focal length
of the eyepiece = magnification.
You see: The magnification is also depends
on the focal length of the telescope tube. This
telescope contains a telescope tube with focal
length of 300 mm. From this formula, we see
that if you use an eyepiece with a focal width of
20 mm, you will get the following magnification:
300 mm / 20 mm = 15 x magnification
Your Telescope
Please look for a suitable location
for your telescope before you begin.
Use a stable surface, e.g. a table.
Mount the telescope to the tripod
with the locating screw for the
vertical adjustment (7). Insert the
eye piece into the diagonal mirror
(6 mm or 20 mm).
Azimuthal Mounting
Azimuthal mounting just means
that you can move your telescope
up and down, left and right, without
having to adjust the tripod.
Use the locating screw for the
vertical fine adjustment (7) and the
locating screw for the vertical axis

When talking about Orion, we‘re actually referring to the main part
of a much larger cloud of hydrogen gas and dust, which spreads
out over half of the Orion constellation. The expanse of this
enormous cloud stretches several hundred light years.
Ring Nebula (M 57)
M 57 in the Lyra constellation
Right ascension: 18:53 (Hours: Minutes)
Declination: -33:02 (Degrees: Minutes)
Distance from Earth: 2,400 light years
The famous Ring Nebula M 57 in the constellation of Lyra is often
viewed as the prototype of a planetary nebula; it is one of the
magnificent features of the Northern Hemisphere’s summer sky.
Recent studies have shown that it is probably comprised of a ring
(torus) of brightly shining material that surrounds the central star
(only visible with larger telescopes), and not of a gas structure
in the form of a sphere or an ellipsis. If you were to look at the
Ring Nebula from the side, it would look like the Dumbbell Nebula
(M27). When viewed from Earth, we are looking directly at the pole
of the nebula.
Dumbbell Nebula (M 27)
M 27 in the Fox constellation
Right ascension: 19:59.6 (Hours: Minutes)
Declination: -+22:43 (Degrees: Minutes)
Distance from Earth: 1,360 light years
The Dumbbell Nebula (M 27) in Fox was the first planetary nebula
ever discovered. On July 12, 1764, Charles Messier discovered this
new and fascinating class of objects. We see this nebula almost
directly from its equatorial plane. If we could see the Dumbbell
Nebula from one of its poles, we would see the shape of a ring,
and we would see something very similar to what we know as the
Ring Nebula (M 57). In reasonably good weather, we can see this
object well even with low magnifications.
Possible objects for observation:
The following section details several interesting and easy-to-find
celestial objects you may want to observe through your telescope. The
pictures at the end of the manual show what the objects will look like
through your telescope’s eyepiece.
Terrestrial objects
Take note of the examples below, including Mount Rushmore and the
golf course. Start with the 20 mm eyepiece and focus until the image
is clear. After mastering the 20 mm eyepiece, switch to the 6 mm
eyepiece and practice scanning and focusing until the image is clear.
Choose several terrestrial objects to practice focusing on, but never
point your telescope at or near the sun, or you risk blindness.
The Moon
The moon is the Earth’s only natural satellite.
Diameter: 3.476km
Distance from Earth: approx. 384,400 km (average)
The moon has been known to humans since prehistoric times. It is the
second brightest object in the sky (after the sun). Because the moon
circles the Earth once per month, the angle between the Earth, the
moon and the sun is constantly changing; one sees this change in the
phases of the moon. The time between two consecutive new moon
phases is about 29.5 days (709 hours).
Orion Nebula (M 42)
M 42 in the Orion constellation
Right ascension: 05:35 (Hours: Minutes)
Declination: -5:22 (Degrees: Minutes)
Distance from Earth: 1,500 light years
Located about 1,500 light years from Earth, the Orion Nebula (Messier
42, abbreviation: M 42) is the brightest diffuse nebula in the sky –
visible with the naked eye, and a worthwhile object for telescopes
of all types and sizes, from the smallest field glass to the largest
earthbound observatories and the Hubble Space Telescope.

Telescope ABC’s
What do the following terms mean?
Diagonal:
A mirror that deflects rays of light 90 degrees. With a horizontal
telescope tube, this device deflects the light upwards so that you can
comfortably observe by looking downwards into the eyepiece. The
image in a diagonal mirror appears upright, but rotated around its
vertical axis (mirror image).
Focal Length:
Everything that magnifies an object via an optic lens has a certain focal
length (FL). The FL is the length of the path the light travels from the
surface of the lens to its focal point. The focal point is also referred to
as the focus. In focus, the image is clear. In a telescope, the FL of the
telescope tube and the eyepieces are combined.
Lens:
The lens turns the light which falls on it around in such a way so that
the light gives a clear image in the focal point after it has traveled a
certain distance (focal length).
Eyepiece:
An eyepiece is a system made for your eye and comprised of one or
more lenses. In an eyepiece, the clear image that is generated in the
focal point of a lens is captured and magnified even more.
There is a simple formula for calculating the magnification:
focal length of the telescope tube / focal length of the eyepiece =
magnification
In a telescope, the magnification depends on both the focal length of
the telescope tube and the focal length of the eyepiece.
Magnication:
The magnification corresponds to the difference between observation
with the naked eye and observation through a magnification apparatus
such as a telescope. In this formula, observation with the eye is
considered “single,” or 1x magnification. Accordingly, if a telescope
has a magnification of 30x, then an object viewed through the
telescope will appear 30 times larger than it would with the naked eye.
Troubleshooting:
Problem: Solution:
No picture Remove dust protection cap
and sun-shield from the

How do I observe the specimen?
Sitting in your location with adequate illumination chosen
from the color filter wheel, the following basic rules should
be observed: Start with a simple observation at the lowest
magnification. Position the object or specimen in the middle
of the stage under the stage clips, centered over the lower
light. Focus the image by rotating the focus knob until a
clear image appears in the eyepiece.
Place the prepared slide directly under the objective on the
microscope stage, and secure it with the stage clips. The
prepared slide should be located directly over the lower
illumination. Look through the eyepiece, and carefully turn
the focus knob until the image appears clear and sharp.
Now you can select a higher magnification by rotating to
the 20x/400x objective turret. Higher levels of magnification
can be achieved by turning the objective turret to a higher
setting (45x/900x). Following this procedure creates a
steady increase of magnification without overpowering the
view of the object. The following magnifications should be
How do I use my microscope?
Before you use your microscope, make sure that the table,
desk, or surface that you place it on is stable and is not
subject to vibration. If the microscope needs to be moved,
hold it by the arm and base while carefully transferring
it. Once the microscope is in a suitable location and the
batteries are installed, check the light source to make
sure that it illuminates. Use a microfiber cleaning cloth to
gently wipe the lenses off. If the stage is dirty with dust or
oil, carefully clean it off. Make sure that you only raise and
lower the stage using the focus adjustment knob.
How do I operate the illumination?
Locate the mirror/light on the base of the microscope. Flip
the mirror/light to the “on” position (with the light facing up)
and the light will illuminate. This microscope is equipped
with an incandescent light that illuminates the specimen
from below. The color filter wheel is located in the middle
of the microscope stage. The filters help you when you
are observing very bright or clear specimens. Using these
filters, you can choose various brightness levels and colors.
This helps you better recognize the components of color
-
less or transparent objects (e.g. sea salt).
How do I adjust my microscope correctly?
Place the microscope in a suitable location as described
above, and sit in a comfortable viewing position. Always
start each observation with the lowest magnification. Adjust
the distance of the microscope stage so that the stage is
in the lowest position, farthest away from the turret head.
Turn the objective turret until it clicks into place at the
lowest magnification (Objective 5x/100x). Note: Before
you change the objective setting, always make sure the
microscope stage is farthest away from turret by rotating
the focus knob. Separating the stage and turret by rotating
the focus knob will avoid causing damage to the specimen
slide or microscope. When starting an observation, always
start with the 5x/100x objective in the rotating head.

considered: 100x, 400x, then 900x. Each time the magnification changes (due to the objective change), the image
sharpness must be readjusted with the focus knob. When
doing this, be careful because if you move the microscope
stage too quickly, the objective and the slide could come
into contact and cause damage to the slide or microscope.
For transparent objects (e.g. sea salt), light is projected
by the lower light traveling from below the stage, through
the objective and eyepiece, and finally into your eye. This
process of light transmission is known as microscopy.
Many micro-organisms found in water, plant components,
and the smallest animal parts are transparent in nature.
Opaque specimens, on the other hand, will need to be
prepared for viewing. Opaque specimens can be made
transparent by a process of treatment and penetration with
the correct materials (media), or by slicing. You can read
more about creating specimens in the following Microscope
Experiments booklet.
