Polar alignment instructions (18-25)
It’s now time to polar align the mount. In the Northern hemisphere we use Polaris, the North Star, as
a guide, while in the Southern hemisphere we use the star Sigma Octantis. We recommend doing
this during twilight, after Polaris or the constellation of Octans become visible. This way, you will be
ready to take photos when proper night sets in.
Just by sighting alongside the tracker, place your tripod so that the Right Acension axis of the
LighTrack II (the rotation axis of the mount) roughly points North or South, depending on where you
are on Earth.
For accurate tracking the base of the wedge needs to be level. The FMW-200 wedge has a bubble
level on its base to guide you through the process. Look at the bubble and see if the system is
parallel to the ground. If the bubble is in the centre of the circle, you’re all set. If not, you will need to
adjust the tripod legs until it’s level.
Now, slide out the polarscope bracket and mount the scope inside it. If you have a different polarscope
than the one we sell, contact us for getting the right adapter for it.
In order to polar align the tracker you will need to move the wedge in two directions: altitude and
azimuth. For altitude movement, you use the two large rotating knobs on the sides of the wedge.
For azimuth motion you use the two long and thin screws on the opposite side of the wedge as your
actual tracker. When moving the wedge in azimuth (left - right), you will have to un-tighten the three
screws on the base of the wedge.
Un-tighten the blocking nuts of the altitude control so that the wedge will easily slide up and down
when you rotate the silver knobs. On the side of the wedge, you will find a latitude scale. Rotate the
silver knobs until you set a latitude as close as possible to the one you are at. Now, look through the
polarscope and try finding Polaris or Sigma Octantis in the field of view. If it’s not there adjust both
altitude and azimuth controls until you get the star in the field of view. Note that you don’t have to
centre the star; it’s the celestial pole that need to be in the centre.
Now, using the different markers in your polarscope field of view, align all items according to the
instructions of the polarscope. We suggest using a polar aligning app to help you in the process as
polarscopes need to be rotated depending on the time of night when you do the alignment. Using
the app will make the process a lot more straight forward.
Once you are happy with your alignment tighten the blocking nuts of the altitude slider and the
blocking screws of the base plate. You are now ready to mount your camera on the tracker, power
it up and shoot.
Clear skies!
