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.

For additional magniﬁcation, you can use the included 3x Barlow

lens. Place the Barlow lens in the diagonal in place of the eyepiece.

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

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.

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.

CONGRATULATIONS!

YOU HAVE NOW OBSERVED YOUR

FIRST CELESTIAL OBJECT!
