Never use an eVscope
to look at the Sun
without an adapted filter!
Looking at or near the Sun
will cause irreversible damage
to your product.
Do not point the telescope at
or near the Sun.
Children should always have adult
supervision while observing.
Never charge an eVscope
if the temperature is under
10° Celsius.
It could cause irreversible damage to
the eVscope’s battery.
Always charge it between
10°C and 40°C.

Instructions
Box content:
- eVscope + Bahtinov mask included in the tube top cover
- Tripod
- Power supply with exchangeable plugs (EU, USA, UK)
- Quick start guide
- User Guide
- Accessories box with tools
Requirements:
-Avoid directly exposing the eVscope to strong wind and try to shelter it from moderate winds to
improve your observations.
-Use the eVscope on stable ground that doesn’t vibrate when you walk near the eVscope.
-Use the eVscope under a clear sky.
-Locate the eVscope away from direct streetlight.
-For best results, avoid a full moon.
In order to use your eVscope, please follow carefully these steps:
1. Setup the tripod: open the legs of the tripod and adjust the device to the height that works
best for you.
Warning: The internal tripod’s screws could have loosened during shipment.
Please check that all screws are tightened. If not, you can tighten them with the specific
tools you can find in the accessories box.!

2. Adjust the legs in order to put the level bubble in the middle of the black circle, as in the
image.
Note: each time you move your eVscope, we recommend resetting the level bubble.
!
3. Loosen the 2 tripod screws. Install your eVscope vertically on the tripod and tighten the "
screws. Be careful not to tighten it too hard.
4. Start the eVscope by pressing the On button for 2 seconds. When you see a red light, "
the eVscope is on and ready to use. "
Warning : if you turn on your eVscope in daylight, you might not see the button light "
because of its low intensity. It has been set up like this so it won’t dazzle you at night. "
"
Battery is not fully charged when shipped.

!
•Remove the dust caps from the top of the tube and the eyepiece.
5. Connection the smartphone:
oDownload the Unistellar app from the
Google Play Store or Apple Store.
oTurn on your smartphone’s Wi-Fi.
oCheck available Wi-Fi networks.
oConnect your smartphone to the
eVscope Wi-Fi network named
eVscope-abcdef (the network’s name
consists of eVscope and six random
characters).
oLaunch the Unistellar app on your
smartphone
oWarning: the connection between
your eVscope and your smartphone
may sometimes be lost, in this case
please restart your application. If you
encounter broken connections, we
advise you to disable Auto-Lock.
6. Focus :
oUsing the in-app joystick, lower the telescope to around 45°.
oBasic focus: Adjust the focusing wheel at the bottom of your eVscope to align
the visual cue with the top screw.
Note : To get a perfect focus, the visual cue might not be exactly aligned with the
top screw to have the perfect focus. You can focus "by eye" or focus precisely
using the Bahtinov mask (recommended for excellent results).

!
oAccurate focus: To ensure perfect accuracy, point the eVscope on a
bright star and use the Bahtinov mask to adjust the focus and the coma
(see Mirror Alignment).
i. Here’s how to focus with the mask. In the « Explore » tab of your app, go to Star and
select the first one. Select « GoTo » to move the eVscope on it. Go to « eVscope »
tab, then touch the Settings icon : on the top right of your screen and activate the
« Auto » mode. Put the mask on top of the tube. This will create a specific diffraction
pattern for that bright star, with a central line and two spikes forming an X, which you
can see in the eyepiece. If the central line is positioned exactly in the middle of X, it
means your eVscope is perfectly focused. To achieve this result, you just need to
manually rotate the bottom of your eVscope and observe the results in the eyepiece.
The orientation of the cross doesn’t matter
ii. In these three images, you can see the star Rigel observed with our mask. The first
two images are out of focus, but by rotating the wheel, we were able to achieve perfect
focus.

!
iii. The Bahtinov mask is included in the cover, in order to use it you should remove
the mask from the cover and install it on the eVscope, as in the pictures.
iv. In case you need to adjust the coma, use the two screws of the adjustment
mechanism (see Mirror Alignment on next page).
7. Observation:
oCheck the Quick Start Guide for detailed explanations on how to use your eVscope.
8. Park:
oWhen you’re done observing, use the « Park my eVscope » function so it automatically
moves to the zenith position and turns itself off. First, the tube will go a little further than
the zenith, then it will slowly go back. You will find the option « Park my eVscope » in the
User tab
oPut the dust caps back on the tube and eyepiece.

oYou can adapt the focus of your observations to your vision by rotating the ring
located on the eyepiece. Do not point at an object (star, galaxy,...) while proceeding
to this adjustment. For optimal results, we advise each user to use the “focus help”
available in the “User” tab of the app (this can be done during the day). You can
also adjust the eyepiece focus while observing, by turning the ring to obtain a sharp
image adapted to your vision.”
oCheck and adjust the mirror alignment (below).
oCheck the battery charge level in the "User" tab
oShare your observations with the community by sending us your data (Download
data, then Upload my data).
oEnjoy the multi-user experience.
oContribute to science by joining eVscope observing campaigns.
oCheck the online FAQ to learn more about your eVscope’s capabilities.
9. To improve your next observations:
oAdjust the gain and the exposure time in Live View mode.
oAdjust the contrast and brightness in Enhanced Vision mode.
oSet up your observing conditions in the Explore settings (city, suburb, countryside)
10. Mirror Alignment
Mirror alignment is advised after each time your eVscope is having a long journey.
oFor this procedure, you will need:
a. The smallest hex key provided in the toolbox (S2
3mm),
b. A clear sky with visible bright stars.

oSet up the eVscope using the 1. INSTALL and 2. CONNECT and 3. FOCUS & TRACK
sections of the Quick Start Guide.
oPoint toward a bright star by selecting a visible one in the list of proposed stars.
oCenter the target using the joystick.
Note: the joystick of the app can be used in 2 different ways: drag the yellow dot for fast
movement or simply touch the edge of the disc for slow movement. The short touches allow
a slow movement. In the "eVscope" tab, display the settings by touching the icon at the top
right and activate the "Auto" mode.
oFully rotate the large focus wheel clockwise without forcing. You should see this :
oIf the dark cross is not centered (as shown in the above image on the left), you need to
realign your mirror.
oFind the smallest hex key (S2 3mm) in the toolbox.
oFirst, move the telescope with the in-app joystick (touch the edge of the circle quickly) to
put the star at the edge in the direction indicated in the table below:
Bad alignment"
(the cross is not centered)
Good alignment"
(the cross is centered)
The cross is too high
Move the star on the top of the image
The cross is too low
Move the star on the bottom of the image
The cross is off-centered on the left
Move the star on the left of the image
The cross is off-centered on the right
Move the star on the right of the image
