Collimation proved to be extremely robust on our prototype. Yet it is sometimes necessary to check the mirror alignment, for example after each time your eVscope is having a long journey.
For this procedure, you will need:
1) The smallest hex provided in the toolbox (S2 3mm),
2) A clear sky with visible bright stars.
- Point your eVscope toward a bright star by selecting a visible one in the list of proposed stars.
- In the settings, set the gain and the exposure time on AUTO.
- Center the target using the in-app joystick.
- With the focusing wheel at the bottom of your eVscope, defocus anticlockwise to the maximum.
You will see something like this :
If the dark cross is not centered (as shown in the above image on the left), you need to realign your mirror.
- Find the smallest hex key (S2 3mm) in the toolbox.
- First, move the telescope with the joystick to put the star at the edge in the direction indicated in the table below:
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 :
- Repeat the procedure until the cross looks centered. You might have to do it several times.
- Move back the focus to the default position by aligning the visual cue with the top screw, then adjust it by rotating the wheel.
- Move toward a target and enjoy. The image should look better !
