Introduction
Unistellar's mission
Unistellar was founded in 2017 by two former laureates of the Nobel Prize
in Physics 2018, a visionary industrial engineer and a world-renowned as-
tronomer from California. The four of them are united by a common goal:
to make astronomy more accessible and exciting for everyone and, in ge-
neral, to bring the universe closer.
Unistellar is revolutionizing the astronomy industry by oering consu-
mer-level telescopes that are both simple to use and powerful enough to
reveal the wonders of the cosmos and lead to new scientic discoveries.
This fun and educational instrument provides access to thousands of ob-
jects. Whether you’re looking at the night sky from a balcony in the city or
out in the country, Unistellar telescopes are the most portable, fastest, and
most user-friendly option.
Our telescopes provide an unrivaled user experience. Not only are they
simple to use, but they also take just minutes to set up. They can even be
controlled through your smartphone and can automatically point to thou-
sands of objects in our catalog.
Our user community can easily upload and share data. This paves the way
for novel experiences like sending valuable scientic data to professional
astronomers or taking pictures of the sky with a large group of people at
the same time.

What is the eVscope?
Enhanced Vision
Enhanced Vision is a proprietary, patent-protected technology that makes it possible
to observe low-light objects in real time by accumulating the light we receive
from them. Galaxies, nebulae, and comets are now visible, colorful, and detailed.
Depending on the observation conditions (light pollution, moon phase, weather, etc.)
and the objects you’re viewing, it can take just a few seconds to begin seeing the
beautiful colors and shapes of galaxies and nebulae that are normally invisible, even
through the eyepiece of a large conventional telescope.
Smart Light Pollution Reduction
Light pollution, or the presence of excessive and unwanted articial lighting, renders
celestialobjects invisible to the human eye. It even challenges cameras and computers
by blurring objects, distorting shapes, and adding noise to images. Unistellar’s
proprietary software quickly reduces the impact of light pollution and allows distant
objects to be observed in sharp detail, even in bright urban environments, delivering
the best possible image settings and results. Regardless of how bright the sky is,
users can enjoy more realistic images with enhanced contrast and color.
A powerful scientic device with a global community
Unistellar explorers can conduct valuable space science research in collaboration
with astronomers from the SETI Institute and other institutions, such as protecting
the Earth, detecting a dangerous asteroid, discovering and conrming the existence
of a celestial body around a distant star, or even unraveling the mystery of a comet
or supernova.
What makes the eVscope so easy to use?
Field recognition
With this telescope, you’ll spend less time setting up and calibrating the telescope
and more time observing space. Our system can instantly identify the objects in its
eld of view by comparing what it sees against a database with information on tens
of millions of stars. This enables the telescope’s automated tracking and pointing
system to be extremely accurate and simple to use, resulting in the most user-
friendly telescope on the market.
Dedicated app
With the touch of a button on the app, your Unistellar telescope can recommend
the most spectacular targets for deep space observation, all in a matter of minutes.
Use the app to learn about and identify cosmic objects, including the most relevant
objects to observe from your location, with a catalog of over 5,000 objects to choose
from. Through the use of our smart technology, you can capture and share your
experience with others, in person or remotely.
The Unistellar app oers engaging educational content and automates your
observing experience, allowing even beginners to enjoy their telescope right away.
The application also oers manual commands for advanced users.

Thermalization
What is thermalization?
Thermalization is the process of balancing the temperature of your telescope’s components
and its surrounding environment.
Why should I thermalize my telescope?
When the telescope’s mirror reaches thermal equilibrium, it performs at its best. This step
is critical to ensuring that the mirror and tube do not warp while in use, potentially causing
changes in focus and image quality.
How do I thermalize my eVscope?
If there is a temperature dierence between the outside and the room where your telescope
is stored, turn on your telescope and place it outside for 15 to 30 minutes before your
observation, depending on the temperature dierence.
Weather and temperature
If the sky is cloudy, you will not be able to observe with your telescope. The telescope is
highly sensitive to wind because it causes vibrations that can interfere with the enhanced
vision.
We recommend using your telescope within the following temperature range:
•O: 50°F to 104°F
•During use and charging: 50°F to 104°F
•During use: 32°F to 104°F

Collimating your telescope
What is collimation?
Collimation refers to the process of aligning the sensor and the mirror’s optical axis. You
do not need to carry out a collimation every time you use your telescope if it has not been
transported in a way that involves lots of movement, such as in the trunk of a car. We
recommend that you perform this operation once and then periodically check for shifts.
If you are having diculty focusing as described in the preceding sections or if you are having
diculty achieving high precision focus with your Bahtinov mask, your telescope may require
collimation.
How often should I collimate my telescope?
Collimation is rarely necessary. It should be done primarily when you transport your telescope in a
way that involves lots of movement, like after a trip in the trunk of a car.
How do I collimate my telescope?
Collimate your telescope using the two screws located
on the bottom of the optical tube. Turning these screws
adjusts the position of the mirror. The top screw is used
to move the star vertically, while the left screw is used
to move it horizontally.
For this procedure, you will need:
1- The T20 Torx wrench (telescope tool 1) supplied in
the toolbox.
2- A clear sky with bright, fully visible stars.
Point your telescope toward a bright star, selecting the
rst star that is recommended in the catalog.
Center it using the joystick in the app.
# Tool 1 (T20 Torx)
Look directly into the eyepiece for this procedure.
Turn the wheel counterclockwise as far as it will go.

Check the collimation for the rst time right after receiving your
telescope.

If the black cross ap-
pears as shown here,
your mirror is correctly
aligned.
If the black cross appears
as shown here, you need to
realign your mirror.
REPEAT THE PROCEDURE UNTIL THE CROSS IS CENTERED. SEVERAL ATTEMPTS MAY
BE REQUIRED.
Turn the focus wheel to align the visual mark. Orient the telescope toward a target and
enjoy the view.
Scan this QR code to be redirected to our
video on collimating your telescope.
Use the T20 Torx
wrench (telescope tool
1) in the toolbox.
Use the joystick arrows to move the telescope so that the star is at
the edge of your screen. Which edge depends on your cross. If the
cross is right of center, use the joystick to place the star on the right
edge of the screen; if the cross is left of center, place it on the left
edge, and so on.
Once the star is on the correct side, turn the vertical or horizontal mirror
mount screw with the T20 torx wrench (telescope tool 1) to adjust the
mirror and re-center the star on the screen and eyepiece.
Use caution with the screws. If you are a beginner, take your time and do not
skip any steps.

English

Adjusting the focus
What is the focus?
The focus is the distance between the mirror and the sensor, which allows rays of light from
the object to converge correctly. The image will be blurry if the light rays converge before or
after the sensor.
How often should I adjust the focus?
Adjust the focus before any observation, including after leaving the telescope outdoors
to thermalize. You may need to readjust your focus during long nights of observation if the
temperature has dropped dramatically or if your other observation parameters have changed.
How do I use the Bahtinov mask for high-
precision focusing?
Go to the rst star recommended in the catalog because it will be the brightest star
available to you.
Separate the Bahtinov mask from the cover. Place it on the telescope’s tube, turning it
gently if necessary to t onto the tube.
This creates an X-shaped pattern visible in the eyepiece and on your screen. Pinch and
zoom on your device to see the X clearly.
If the pattern you see resembles the image below, your focus is complete.
Slowly turn the wheel until the line is centered in the X image.
The Bahtinov mask has three grills at
three dierent angles. It creates points of
diraction that allow for precise focusing.

Orientation or Autonomous Field Detection (AFD)
What is AFD?
Autonomous Field Detection (AFD) is an algorithm that accurately identies any object in
the telescope’s eld of view by using an internal map containing tens of millions of star
coordinates.
What does AFD do?
AFD automatically points to objects in the night sky, making it easier to look for targets. It
also provides information about what you are observing, such as the distance from Earth,
the size, the age, and more.
Observation tips
Sensor calibration
(or dark frame)
What is the puprose of a dark frame ?
In digital photography, taking a dark
frame means recording an image
with no signal or noise. This process
improves your observations as well
as the quality of your images. A dark
frame enables the telescope’s onboard
computer to analyze and correct the
sensor’s inherent electronic noise.
How do I take a dark frame?
To take a dark frame, leave the cap on the telescope and make sure that you
are in a dark place. Do not expose the telescope to direct light.
Go to the user tab: My eVscope.
If an error message appears, try again later, ideally in a darker setting. It may be that too
much light was detected on the image.
Noise can occur during long exposures
or strong variations in temperature. The
appearance of hot pixels (red, blue or
green spots) on your images can reveal
the eects.
At what frequency should I take a dark frame?
Dark frames can be taken at any frequency you like. We recommend taking at least
one in the winter and one in the summer, as changes in temperature and altitude can
cause imperfections in the images. A dark frame should also be taken before each
scientic observation.
