Collimation
While the Hyperion was collimated and tested before being shipped, it likely will need
some slight adjustment after arrival. This section describes the full procedure for
properly collimating the Hyperion. The adjustments should be made in the order outlined
below.
Secondary Mirror Tilt
This is best evaluated using an optional laser collimator. Use the included 2” end cap for
the Feathertouch focuser to attach the laser collimator.
With the laser in place, look in the front of the scope. Look for the reflection of the
secondary mirror in the primary mirror. You should see the laser being emitted from the
bottom of the laser collimator. You should also see that the beam bounces off the
secondary and returns right on itself. If you see two red spots on the collimator, the beam
is not returning exactly onto itself and you need to adjust the secondary mirror.
This adjustment is done using the secondary collimation bolts. In order to adjust the
secondary mirror tilt, begin by loosening one of the collimation bolts (say, ¼ turn), then
tighten one or both of the other bolts. Remember that the bolts are the only thing holding
the secondary mirror assembly, so do not loosen them too much. Once the laser beam is
returning exactly on itself, the secondary mirror is approximately collimated.
