USING THE STARPOINTER
Although you won’t need to rely on the StarPointer red-dot
finder when you are using the StarSense Explorer app, it can
help you align the app with the telescope. The StarPointer
also comes in handy when you are locating objects during
the day, since the app only works under the stars at night.
To align the StarPointer, first point the telescope at an
object that is at least ¼ mile away. We recommend aligning
during the day. Choose a distant tree, sign, building, or
other landmark. If you are aligning at night, you can use a
streetlight, the Moon, or a bright star or planet.
Once you have pointed the telescope at the object, check
to ensure that it appears in the eyepiece. Next, turn the
StarPointer on using the LED dial (Figure 7).

Turn up the brightness level until you can easily see the
red dot. Now, without moving the telescope, use the
StarPointer’s altitude and azimuth adjustment knobs to
center the red dot on the same object that you centered
in the telescope eyepiece. When you’re finished, check
to make sure the object is still centered in the telescope
eyepiece. If it is, you are done aligning the StarPointer. If
not, move the telescope so the object in the telescope’s
eyepiece is centered again. Continue using StarPointer’s
altitude and azimuth adjustment knobs to center the red dot
on the object again.
Turn off the StarPointer when you aren’t using it to conserve
its battery. While the StarPonter’s battery should last a long
time, eventually it will need to be replaced with a CR2032
3V Lithium button cell battery. These are very common and
available from a wide variety of retailers.
To replace the battery:
1. Use a Phillips-head screwdriver to remove the battery
cover securing screw (Figure 8).
Figure 8: To open the StarPointer’s battery cover, first remove the
securing screw.
2. Remove the discharged battery from the battery com-
partment. You may need to use a knife or screwdriver to
pry the battery out of its holder.
3. Insert the new battery so that the positive side is visible to
you. Make sure the battery is properly seated within the
battery compartment (Figure 9).
Figure 9: When the battery is properly seated in the compartment as
shown, the battery cover should be easy to reinstall.
4. Close the battery compartment and reinstall the securing
screw.
