Before using the
Polar Scope
for polar alignment, the
Polar Scope
itself must be
calibrated to ensure the pattern in the
Polar Scope
is aligned to the mount’s R.A. axis. The
following steps will outline how to calibrate the
Polar Scope
.
Calibrating during daytime
is strongly recommended :
1. Choose a fixed object (the Polaris at night, or a faraway object in daytime); orient
Star
Adventurer
to put the crosshair of the
Polar Scope
exactly on the chosen object.
2. Rotate the mount in R.A. axis for half a turn.
3. If the object remains exactly behind the crosshair in the
Polar Scope
after the rotation,
then it means the
Polar Scope
is aligned to the R.A. axis and no calibration is needed.
4. If, during rotation, you see the object wandering off, calibration is needed. You should
rotate the
Star Adventurer 2i
to find the point where the object is at the longest distance
from the crosshair center, and then you should move the crosshair halfway towards the
object (Fig 2), using the 3 tiny adjustment screws on the side of the
Polar Scope
(Fig 1). A
1.5mm Allen wrench is needed.
IMPORTANT WARNING: Adjusting with the very small Allen screws is delicate. Read the
note below.
