Collimation
If you are having diffi culty achieving focus as outlined in previous sections, or if you are
struggling to achieve a high-precision focus using your Bahtinov mask, your eVscope 2 may
require collimation.
What does collimation mean?
Collimation refers to the process of aligning the optical axis of the mirror (located at the bottom
of the tube) and the sensor (located at the top of the tube). This is a diff erent process than
focusing your eVscope 2 and does not need to be completed as frequently.
How often should I collimate my eVscope 2 ?
Collimation is required infrequently : mostly when you transport your eVscope with too much
agitation for instance after transporting it in the trunk of a car.
How to collimate my eVscope 2 ?
Collimate your eVscope 2 using the two screws located
at the bottom of the tube. When you turn these screws,
it adjusts the mirror position. The top screw will be used
to move the star vertically and the left screw will be
used to move the star horizontally.
For this procedure, you will need :
1 - The torx key (T20) provided in the toolbox,
2 - A clear sky with visible bright stars.
Point your eVscope 2 toward
a bright star by selecting the
fi rst recommended star in
the catalog.
Center the target using the
in-app joystick.
Defocus by turning the focus
wheel counterclockwise to
the maximum.
Check the collimation right after receiving your eVscope 2 for
the fi rst time.
Look directly through the eyepiece for this procedure.
