Lift the bungee straps and slide your smartphone
between the straps and the adapter body so that the
camera is looking through the camera opening. The
straps should provide plenty of tension to hold the
device securely against the adapter.
Now take the adapter with the phone and eyepiece
attached and insert the chrome barrel of the eyepiece
into the focuser of the telescope. Secure it in place
by tightening the setscrews on the focuser.
ADJUST THE FINDERSCOPE
Without moving the telescope, use the two
adjustment screws on the finderscope to move the
red dot appears over the object you are observing in
the telescope’s 26 mm eyepiece.
TIP: Try adjusting one screw at a time. Loosen one
screw by half a turn and tighten another by
the same amount to ensure the finderscope is
securely held in place.
CENTER THE TARGET IN THE EYEPIECE
Look through the telescope using your lower power
26mm 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.
Loosen the setscrews on the eyepiece holder on the
bottom side of the adapter. Place the black portion of
the eyepiece into the eyepiece holder and tighten the
screws to secure the eyepiece in place.
NOTE: You may have to remove the rubber eyecups
from the eyepiece.
Activate the camera app on your smartphone and
adjust the focus, just as you would with an eyepiece,
using the image that appears on your phone’s screen.
NOTE: Make sure you turn the phone’s flash is
turned off.
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 26mm eyepiece,
look through the finderscope and locate the red dot

Your First

The best and easiest target for you to view first is
the Moon. Try observing the Moon at different points
in its phase cycle. The best time to view the Moon
is from two days after a New Moon up to a few days
before a Full Moon. During this period, you will be
able to see the most detail in the craters and lunar
mountain ranges.
With the Moon visible in the sky, set up your
telescope as described above with the 26 mm
eyepiece installed.
Move the telescope so that it is roughly pointing
toward the Moon.
Look through the finderscope and locate the red
dot. Continue moving the telescope until the red dot
appears over the Moon.
Look through the telescope’s 26 mm eyepiece.
Gently turn the focus knobs to adjust the sharpness
of the image.
CONGRATULATIONS! YOU HAVE NOW
OBSERVED YOUR FIRST CELESTIAL OBJECT!
To get a closer view of the Moon, loosen the
setscrews on the focuser and remove the 26 mm
eyepiece. Replace it with your 9.7 mm eyepiece
and tighten the setscrews to secure it in place. The
9.7 mm eyepiece will give you significantly more
magnification, making the Moon appear much larger.
NOTE: You may need to adjust the focus knobs when
you change eyepieces, so make sure you are
getting the sharpest image possible.
You can view many other celestial objects, such as
planets, star clusters and nebulae using this same
technique if you know where to find them in the night
sky. Celestron’s free SkyPortal app for iOS and
Android can help you locate and identify a wide array
of celestial objects quickly and easily.
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, like a streetlight,
license plate or sign. The object should be as far
away as possible, but at least a quarter mile away.
SOLAR WARNING: Never attempt to view the sun through
any telescope without a proper solar filter.
