Optics that are out of collimation (when a set of optics is out of alignment) yield images that are less then perfect.
For example stars will not come to a pin point focus and planets will look slightly hazy. The best way to prevent this
from happening is to collimate your Newtonian telescope with a laser collimator.
Collimating a reflector is easy! Simply place the laser collimator in your telescope's focuser. Turn it on and the beam
of the laser will reflect off the optics of your telescope and finally return to the 45 degree aluminized surface on the
side of the laser collimator (this is the same point at which the laser beam is projected from the laser collimator). If
the laser returns to the point at which the laser is projected then your optics are collimated. If the laser returns
anywhere else on the aluminized 45 degree surface your telescope is out of collimation and the proper adjustments must
The laser collimator is factory aligned using the three recessed screws on its body. Do not adjust these or your
collimator will not work properly. The laser is powered by three LR44 lithium batteries that are supplied with the unit.
Caution: The laser used in this collimator is a 5mw laser. This laser is safe and used in most common laser
collimators. However, your eye should not receive direct exposure from this laser or direct exposure from this laser
being reflected off of the mirror of your telescope as it can cause permanent eye damage. Be careful when using this
collimator and keep out of reach of children.
