USING THE STARPOINTER
Although you won’t need to rely on the StarPointer red-dot
fi nderscope when using the StarSense Explorer app, it can
help you align the app with the telescope. The StarPointer
also comes in handy when locating objects during the day
since the app only works under the stars at night.
To align the StarPointer, point the telescope at an object at
least a quarter mile away. We recommend aligning during
the day. Choose a distant tree, sign, building, or other
landmark. If you align at night, you can use a streetlight, the
Moon, or a bright star or planet.
Once you have pointed the telescope at the object, ensure
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 you centered in
the telescope eyepiece. When you’re fi nished, ensure the
object is still centered in the telescope eyepiece. If it is,
you have aligned the StarPointer successfully. If not, move
the telescope so the object in the telescope’s eyepiece is
centered again. Use the 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, you’ll need to replace it with a CR2032 3V Lithium
button cell battery eventually. These batteries are easy to
fi nd at a 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, fi rst remove the
securing screw.
2. Remove the discharged battery from the battery com-
partment. You may need 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. Ensure the battery is seated correctly 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.
