Quick Setup Guide
Place the accessory tray on top of the center brace
and line up the three holes. Insert the three thumb
screws through the bottom of the leg brace and
thread them into the tray.
To attach the slow-motion knobs to your mount,
first locate the supplied hex key hidden inside the
slot in the front of your mount.
Place the slow-motion control knob over the
D-shaped gear shaft and push inward to make sure
it is fully seated. Use the hex key to tighten the
setscrews onto the gear shaft. Return the hex key to
its storage position in the front of the mount.
Hold the telescope tube next to the mount with the
dovetail bar on the tube facing the clamp on the top
of the mount arm.
Slide the dovetail bar into the clamp at the top of
the mount and tighten the hand knob on the bottom
of the clamp to secure the telescope in place.
Locate the erect image diagonal and remove the
plastic covers. Insert the barrel of the diagonal into
the focuser and secure in place by tightening the set
screws.
Insert the barrel of the 25 mm eyepiece into the
diagonal and tighten the set screw.

To install the StarSense phone dock, insert the
bayonet mount on the side of the dock into the
port on the side of the mount opposite the dovetail
clamp.
Slide the finderscope bracket into the dovetail slot
on the telescope tube near the focuser. The large
window on the finder should be facing the front
of the telescope. Secure the bracket by tightening
the setscrew on the dovetail slot.
Line up the arrow on the dock with the alignment
mark on the mount and press inward while turning
the dock counterclockwise until the orange release
button snaps into place in the hole on the dock.
To remove the dock, press the orange release button
and turn the dock clockwise until the bayonet mount
releases.
Remove the lens cap from the front of the
telescope. To observe, look through the eyepiece
as shown above. Focus the image by turning the
knobs below the focuser.
There is a small clear plastic tab inserted between the
battery and the contact. This was included to prevent
the battery from discharging during shipment. Pull
this out to allow your battery to work.

The StarSense Explorer DX mount has slip clutches
in both axes. To make large movements with the
telescope, simply hold a tripod leg with one hand
and use the other hand on the telescope tube to
push the telescope in the desired direction.
To make fine adjustments or to track celestial
objects, turn both slow motion knobs as required.
Moving the
Telescope
CENTER THE TARGET IN THE EYEPIECE
Look through the telescope using your lower
powered eyepiece. Move the telescope until the
object you chose lies in the center of the view. If the
image is blurry, gently turn the focus knobs on either
side of the telescope until it comes into sharp focus.
NOTE: The image in your telescope may appear
inverted. This is perfectly normal in an
astronomical telescope.
Aligning the
Finderscope
The finder is one of the most important parts of your
telescope. It helps you locate objects and center
them in the eyepiece. The first time you assemble
your telescope, you need to align the finder to the
telescope’s main optics. It’s best to do this during
the day*.
*SOLAR WARNING! Never attempt to
view the Sun through any telescope without
a proper solar filter!
CHOOSE A TARGET
Take the telescope outside during the day and find
an easily recognizable object, such as a streetlight,
car license plate or sign. The object should be as far
away as possible, but at least a quarter mile away.
ADJUST THE FINDERSCOPE
Without moving the telescope, use the two
adjustment knobs to move the finder around until
the red dot appears over the same object you are
observing in the telescope’s 25 mm eyepiece.
YOUR FINDERSCOPE IS NOW ALIGNED!
It should not require realignment unless it is bumped
or dropped.
LOOK THROUGH FINDERSCOPE
Once the object is centered in your 25 mm eyepiece,
look through the finderscope and locate the red dot.

Your First
Night Out
Congratulations! Your telescope is now set up
and you are ready to explore the cosmos. Take the
telescope outside, insert your 25 mm eyepiece,
remove the lens cap, insert your smartphone into the
holder, and launch the StarSense Explorer app. The
tutorial in the app will walk you through the steps on
finding your first astronomical target.
Attaching the
Smartphone
Remove the large cap covering the mirror on the front
of the StarSense dock.
Pull open the spring loaded slider on the top of the
phone dock and set the phone into the holder so
it is flush with the bottom lip of the phone holder.
Slowly release the slider to secure the phone in
place. Most phones fit into the dock with the case
on. However, you may need to remove your phone
case if it is especially bulky or unable to fit into the
clamp (i.e. folio style cases).
