The Zoomion® Viking 60 AZ
Congratulations on the purchase of the new Zoomion ®Viking 60 AZ. This small telescope will give you
hours of fun, with its all optical glass lens and super compactness, and it is the ideal companion to
start in the world of amateur astronomy. With this telescope you will be able to see the craters on
the Moon, star clusters, some nebulae and a glimpse of the Jupiter disc features and its Galilean
moons and the rings of Saturn. We have included many accessories so it will be easy to use this
telescope.
1. Included parts
we have included several accessories that will make the use of the telescope easier and fun, please
take a look at the list of the parts so you can identify them in the future.
1. 1.5x Erecting Lens;
2. 2x magnification Barlow Lens;
3. 5x Finderscope;
4, 5, 6 and 7. Four eyepieces 1.25” (31.75mm); a H20mm H12.5mm, H6mm and a SR4mm eyepiece;
8. Moon filter;
9. Diagonal mirror (not shown).
2. Getting Started. It is very simple to get started.
Here is how the telescope works. The telescope
main lens should point to the object being
observed. This lens will gather the light coming from
the object and sends it through the telescope tube
to the back of the telescope.
At the back there is the focuser. The focuser moves
to get a precise focused image. At the focuser one
can use the supplied accessories. Different
accessories combinations give different results, such
as different image magnifications or correct image.
But all this will be explained in detail in the next
pages.
3. Assembly. Start by setting the tripod. Open the
tripod legs as shown (figure 2). Place the tripod tray and thread it (figure 3). You can use the tray to
put your eyepieces or other observing accessories. The optical tube is placed in the fork mount
(figure 4). Use the two supplied handknobs to secure the telescope to the fork mount (figure 5), turn
this knobs gently, the tube should freely move up and down with a small friction. Make sure that the
telescope is pointing to the right direction. Now slide the chromed shaft in the fork chromed support
(on the side of the fork mount –figure 6). Then thread the shaft to the optical tube chromed
support. Moving the telescope up and down slides the chromed shaft on the fork chromed support.
Place the tube horizontally and tighten the chromed hand knob on the chromed support. Next step
is to place the finderscope. The finderscope base fits the two protruding screws on the telescope
tube (figure 8). Affix the finderscope with the two supplied chromed thumbnuts. The telescope
should look as shown (figure 9). Insert the diagonal and the lowest power eyepiece (H20) in the
focuser tube. Use the focuser thumbscrew and the diagonal thumbscrew to get all parts securely
tightened. The diagonal with the eyepiece should be pointing up (figure 7). Congratulations! You are
almost ready to use the telescope!

4. Start using your Zoomion 70 AZ
telescope. Point the telescope to a distant
object during the day. It is important to do
this during daylight so that you get
familiarized with the telescope operation. A
good target is a church tower a chimney or a
distant mountain peak.
Rotate the focuser knob so that the focuser
tube moves in and out. Do this slowly. We
suggest that you start by racking the focuser all the way in and slowly move it out. With the H20mm
eyepiece you should be able to get a focused image easily.
4.1. The Finderscope. Before we mentioned the Finderscope as a valuable tool to point the
telescope at an object. To operate properly, the telescope and the finderscope, should be aligned.
The image obtained through the finderscope has a much broader field of view than that of the
telescope. Aligning means matching the telescope image to the image of the center of the
finderscope. This way when looking through the finderscope one know the telescope is pointing
exactly to the same point making looking at objects much more easier.
4.2. How to align de finderscope? You have the house chimney (example mentioned before)
centered at the telescope eyepiece field of view. Now look through the finderscope. The small cross
(recticle) at the center of the finderscope field of view should match the center of the telescope field
of view. Adjust the three finderscope screws to get the cross pointing to the same object as the
telescope (as shown in Figure).
ATTENTION! Do not look through the
telescope at the Sun. Concentrated Sun
light cause serious eye injury. Children
should use only with adult supervision.

4.2.1. A distant object is centered at the telescope’s
field of view. In this example we have a house with a
chimney. The chimney is the reference point to place
at the center of the field of view. We first look
through the telescope with the lowest magnification
possible (H20mm should be preferrable). So we have
the widest field of view.
4.2.2. Looking through the finderscope we see the
same building but in this case the chimney is not
centered. We adjust the finderscope using the three
thumbscrews so that the finderscope moves slightly.
This is enough to correct the objects position in the
finderscope. Trial and error is required to get a
satisfactory result. Make sure to tighten the 3 screws
after finishing so that the finderscope tube does not
move.
4.2.3. After playing with the three findercope
thumbscrews and some trial and error we get the
finderscope recticle close to the center (in this case
the chimney). The Finderscope is now ready to use!

5. Using the accessories, a bit of math to
understand how all it works.
Using the accessories is easy and fun. To
change magnification simple swap eyepieces.
To get more magnification simply use the
barlow lens. But how all of this work?
5.1. Power (magnification)
Your telescope as a focal length of 900mm.
This is approximately the distance between
the telescope lens to its focal point (very
similar to the distance between the focus
point of a loupe and the loupe lens). This is a
very important feature that allows to
determine several interesting facts such as
magnification.
The magnification is determined by the
telescopes focal length and the used
eyepiece. You probably noticed that the two
supplied eyepieces are H20mm and H6mm.
This means that the H20mm is a 20mm focal
length eyepiece while the H6mm is a 6mm
focal length eyepiece.
To determine the magnification just devide
the telescope focal length by the eyepiece
focal length. Lets give an example for our
telescope and the supplied eyepieces:
Telescope focal length is 900mm
H20 eyepiece focal length is 20 mm
900𝑚𝑚
20𝑚𝑚 =45 𝑝𝑜𝑤𝑒𝑟
This means that the H20 eyepiece provides a
45x power (magnification). This seems low but
try it, you will see a a bright image with some
very good detail.
5.2. Barlow Lens
The barlow lens is a very interesting device. It
is a negative lens that multiplies the
telescopes focal length. So a 2x Barlow
multiplies the original focal length by 2x, in
this case 900𝑚𝑚 𝑥 2 = 1800𝑚𝑚.
A 3x Barlow lens multiplies by 3x.
Your telescope is supplied with a 2x Barlow
lens. When used with the H20 eyepiece you
get 2x the power obtained before
45𝑝𝑜𝑤𝑒𝑟 𝑋 2𝑥 𝐵𝑎𝑟𝑙𝑜𝑤 = 90 𝑝𝑜𝑤𝑒𝑟
5.3. Erecting lens
The erecting lens gets you a upright image
view with the telescope. It also adds some
power like the barlow lens. The supplied
Erecting Lens provides and extra 1.5x power.
5.4. Diagonal Mirror
This diverts the light coming from the
telescope to an angle of 45 or 90 degrees. It is
useful because it provides a more confortable
position when observing.
Here are some examples on how to use the
accessories.

6. What can been seen with this telescope?
Below you will find some examples of what you can expect to see when using this telescope.
6.1. The Moon is one of the most spectular objects
to be seen through a telescope. Even a small
telescope will reveal high detail of the Moon’s
surface. You will be able to see the craters on the
Moon’s surface and other features like the Marea.
The moon is a very bright object. It is better
observed when the Moon is not full. Try the
crescent Moon and look for features along the
terminator (between illumated and dark surfaces).
6.2. Jupiter is the biggest planet of our solar system.
It is also on of the favorite targets for beginners.
Galileo was able to discover that the four tiny dots
that turn around the planet were in fact part of
Jupiters system of moons. With this telescope you
will be able not only to see Jupiter’s planet disc with
its two major discernible bands but also its biggest
moons, Io, Europa, Ganymedes and Callisto.
6.3. The “lord of the rings” of the night skies, Saturn
is by far the most popular target for small
telescopes. Saturn’s rings are discernible even at
60x magnification. In a very good night you will be
able to see the Cassini’s division (the darker band
on the Saturn’s rings).

7. Troubleshooting and frequently asked questions
Q: I can’t get to focus my telescope, only get a bright circle.
R: Make sure you have inserted the Diagonal and an eyepiece (start by the lowest power eyepiece –
H20). Point to a distant object during the day and proceed as described in 4.
Q: I get a mirrored view of the objects. Like if they were reversed, and R show up like ᴙ
R: This is caused by the
Diagonal Mirror. It has a
mirror inside. To get a
corrected image it is
necessary to use the
Erecting Lens and the
Eyepiece as shown below.
Q: I use the finderscope
to point to objects but I always miss the target.
A: You probably need to realign the finderscope. Please proceed as described in 4.2.
Q: When I use the barlow lens and the H6 eyepiece the image is so dark I can’t hardly see anything.
A: Power should be used with moderation. It depends on how stable the atmosphere is, too much
turbulence causes image distortion. Usually the limit is 2x for each millimeter of the telescope
aperture. In this case this telescope, the telescope has an aperture of 70mm so in a very good night
you should be able to reach 140x. The more magnified the image is the darker it gets.
Q: Is my telescope compatible with other eyepieces ?
A: Zoomion telescopes are compatible with all telescope eyepieces from different manufacturers as
long as the eyepiece is a 1.25” (or 31.75mm) size eyepiece. If you would like to test an eyepiece from
a fellow astronomer go ahead. Different eyepieces provide different visual experiences.
Q: I want to use my telescope to take pictures
A: This telescope is designed for visual use. It doesn’t mean it can’t be used for photography, however
it will be hard to get high quality pictures with this telescope. If you have a smartphone you can shoot
the Moon or some terrestrial objects. Search online for digiscoping and afocal photography.
Q: The stars only appear as points in the telescope
A: Stars will always appear only as points, even in the largest telescopes in the world. It is more
interesting for beginners to observe two-dimensional objects, such the moon or planets. Once you
find these, you will be able to start learning about the astronomical calendar.
Q: I would like to observe the Sun
A: An appropriate solar filter, placed over the objective, is essential for observing the sun. These are
available as plastic foil or glass filters. They allow only a tiny and harmless fraction of sunlight into
the telescope when securely positioned over the objective, so allowing you to observe the sun in
complete safety. Eyepiece solar filters (not available from us) should be avoided at all costs as they
are considered unsafe. Note: Never look directly at the sun through a telescope without an
objective solar filter!
Q: I can’t see anything when I look through my telescope
A: The telescope is only suitable for astronomical observing and when used outside at night.
Observing from inside the house or during the day is not usually possible.
The dust caps must first be removed and an eyepiece inserted before you can start observing. Are
you sure you have you removed all the dust caps, not just the small ones? If you have not, then no
light will enter the telescope and everything will appear black.
