2. Adjust the legs in order to put the bubble level 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: o Download the Unistellar app from the Google Play Store or Apple Store. o Turn on your smartphone's Wi-Fi. o Check available Wi-Fi networks. o Connect your smartphone to the eVscope Wi-Fi network named eVscope-abcdef (the network's name consists of eVscope and six random characters).
o Launch the Unistellar app on your smartphone
o Warning: 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 : o Using the in-app joystick, lower the telescope to around 45�. o Basic 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).

Page 6

V.3.1

o Accurate 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.

V.3.1

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: o Check the Quick Start Guide for detailed explanations on how to use your eVscope.
8. Park: o When 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 o Put the dust caps back on the tube and eyepiece.

V.3.1

9. To improve your next observations: o Adjust the gain and the exposure time in Live View mode. o Adjust the contrast and brightness in Enhanced Vision mode. o Set up your observing conditions in the Explore settings (city, suburb, countryside)

o You 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."
o Check and adjust the mirror alignment (below). o Check the battery charge level in the "User" tab o Share your observations with the community by sending us your data (Download
data, then Upload my data). o Enjoy the multi-user experience. o Contribute to science by joining eVscope observing campaigns. o Check the online FAQ to learn more about your eVscope's capabilities.
10. Mirror Alignment Mirror alignment is advised after each time your eVscope is having a long journey.
o For this procedure, you will need:
a. The smallest hex key provided in the toolbox (S2 3mm),
b. A clear sky with visible bright stars.

Page 9

V.3.1

o Set up the eVscope using the 1. INSTALL and 2. CONNECT and 3. FOCUS & TRACK sections of the Quick Start Guide.
o Point toward a bright star by selecting a visible one in the list of proposed stars.
o Center 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.
o Fully rotate the large focus wheel clockwise without forcing. You should see this :

Bad alignment
 (the cross is not centered)

Good alignment
 (the cross is centered)

o If the dark cross is not centered (as shown in the above image on the left), you need to realign your mirror.
o Find the smallest hex key (S2 3mm) in the toolbox.
o First, 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:

The cross is too high The cross is too low The cross is off-centered on the left The cross is off-centered on the right

Move the star to the top of the image Move the star to the bottom of the image
Move the star to the left of the image Move the star to the right of the image

Page 10

V.3.1

o Then turn the vertical or horizontal screw in the mirror mount to put the star back at the center. For example, if the cross is too high :
Ver$cal Horizontal

1. Put the star on the edge of the screen with the in-app joystick.


2. Use the hex key to turn the screw (in this example the vertical screw)

3.Put back the star at the center of the screen. The cross will recenter itself

o Repeat the procedure until the cross looks centered. You might have to do it several times.
o Move back the focus to the default position by aligning the visual cue with the top screw (Section 3 in the Quick Start Guide).
o Move toward a target and enjoy. The image should look better now.

11. Charge/Discharge
o The eVscope can be used while charging. o It can take from 7 to 8 hours to fully charge it. o When the eVscope is charging, you will see a blue flashing LED that will go from six
flashes to none. Flashes decrease as the battery gets more charged. o We strongly advise not to recharge your eVscope below 10�C. o When the battery is low, the performance of the eVscope can be compromised. You
can see the battery charge level in the "User" tab of the app. A fully charged battery is all yellow, a fully discharged battery is black with a yellow border. o We advise to only use the USB-C charger provided by Unistellar. o You can also use an external battery to recharge your eVscope. o You can charge your smartphone with the eVscope. Plug it to the USB-A port, next to the USB-C port.
