POWERING THE NEXSTAR SLT
The NexStar SLT can be powered by 8 user-supplied AA
size alkaline batteries or an optional 12V AC adapter To
install batteries into the NexStar SLT:
1 Squeeze the tabs on both sides of the battery compartment
cover while lifting upward
2 Insert 8 AA batteries into battery compartment holders
3 Place the battery compartment cover over the batteries and
push down until the cover snaps in place
4 Flip the power switch to the "On" position The light on the
power button should come on
In case of a loss of power, the optical tube can be moved
by hand. However, when powered on, the telescope
should always be controlled via the hand control. The
NexStar SLT will lose its star alignment if moved by hand
when powered on.
STARPOINTER OPERATION
The StarPointer finderscope helps you aim your telescope by looking through its round glass window and covering your
target with the red dot projection The first time you assemble your telescope, you will need to align the StarPointer
with the main optics of the telescope Although this step can be done at night, it is significantly easier during
the day. Once you have completed the finderscope alignment, you should not have to repeat this step unless the
finderscope is bumped, dropped, or removed during transit To align the StarPointer:
1 Take the telescope outside during the day Using your naked eye, find an easily recognizable object, such as a streetlight, car
license plate, or tall tree The object should be as far away as possible, but at least a quarter mile away
2 Remove the main dust cover from the telescope and make sure your lowest power (longest focal length) eyepiece is installed
in the focuser
3 Power on your telescope and use the directional buttons to position the tube so that it is roughly pointing toward the object
you chose in step 1
4 Look into the eyepiece and use the directional buttons to move the telescope until the object you chose is perfectly
centered in the field of view If the image is blurry, gently turn the focus knob until it comes into sharp focus
Note: The image in the telescope eyepiece may appear upside-down or mirror reversed, depending on the type of
telescope you have. This is perfectly normal in an astronomical telescope.
5 Once the object is centered in your eyepiece, turn on the finderscope by turning the power switch knob clockwise as far
as it will go
6 With your head positioned about a foot behind the StarPointer finderscope, look through the round window and locate the
red dot It will probably be close to, but not on top of, the object you see when you are looking through the eyepiece
7 Without moving the telescope, use the two adjustment knobs on the side and underneath the StarPointer One
controls the left-right motion of the dot, while the other controls the up-down motion Adjust both until the red dot appears
over the same object you are observing in the 25mm eyepiece
Now choose some other distant targets to practice aiming your telescope Look through the StarPointer window and
place the red dot on the target you are trying to view and verify that it is in the eyepiece of the scope
Note: Be sure to turn off the StarPointer finderscope when not in use to conserve battery power. New batteries can be
purchased online or at watch/electronic stores.
