Celestron 80AZS User manual

ENGLISH | 1
Unpack your telescope and verify that all parts are present. Your
PowerSeeker 80AZS includes: an optical tube with two threaded
mounting bolts, a tripod with center support bracket, two eyepieces,
a 3x Barlow lens, a finderscope, an erect image diagonal, and an
eyepiece accessory tray.
Check to ensure that all three legs are the same height once
extended to provide a level platform for the telescope.
Locate the optical tube and insert the attached slow motion control
rod into the hole on the mount.
To set up the tripod, spread the legs outward until they are fully
extended and push down center leg brace.
Place the eyepiece accessory tray on top of the tripod’s center leg
brace. Thread the tray into the threaded hole in the center of the leg
brace until it is fully seated.
Extend the center portion of each of the three tripod legs down about
6 to 12 inches. Use the tightening screw on each leg to secure the
extended leg in place.
If necessary, rotate the accessory tray counterclockwise until
the accessory holes are not covered by the leg brace arms as
shown here.
Line up the tube with the holes on the mount and secure the tube
to the mount using the two threaded mounting bolts. Tighten to
secure in place.

Locate the diagonal and remove the plastic covers. Insert the barrel
of the diagonal into the focuser and secure in place by tightening
the set screws.
Locate the finderscope and remove plastic caps on front and back of
lens. Orient the finderscope so that the longer lens is facing towards
the front of the tube as shown here. Place finderscope over the posts
on the tube and replace knurled nuts to secure.
Loosen the screws on the focuser so they do not obstruct the
inner diameter of the focuser. Remove the plastic cap covering the
end of the focuser.

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!
ALIGNING THE
FINDERSCOPE
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.
STOP
5
CENTER THE TARGET
IN THE EYEPIECE
Look through the telescope using your lower powered
20mm 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.
LOOK THROUGH FINDERSCOPE
Once the object is centered in your 20mm eyepiece,
look through the finderscope and locate the
crosshair reticle.
3
ADJUST THE FINDERSCOPE
Without moving the telescope, use the three finger
knobs surrounding in the finderscope bracket to move
the finder around until the crosshair appears over the
same object you are observing in the telescope’s
20mm 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.
YOUR FINDERSCOPE IS
NOW ALIGNED!
It should not require realignment unless it is bumped
or dropped.

The best and easiest target for you to try 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.
YOUR FIRST NIGHT OUT
THE MOON
With the Moon visible in the sky, set up your telescope
with the 20mm eyepiece installed.
Look through the telescope’s 20mm eyepiece.
Gently turn the focus knobs to adjust the sharpness
of the image.
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.
To get a closer view of the Moon, loosen the set
screws on the focuser and remove the 20mm eyepiece.
Replace it with your 4mm eyepiece and tighten the set
screws to secure it in place. The 4mm 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.
Move the telescope so that it is roughly pointing
toward the Moon.
Look through the finderscope and locate the crosshair
reticle. Continue moving the telescope until the
crosshair appears over the Moon.
