Introduction
Congratulations on your purchase of a PowerSeeker
telescope. The PowerSeeker Series of telescopes come
in several different models and this manual covers four
models mounted on Alt-Az Mounts ((an altazimuth is the
simplest type of mount with two motions – altitude (up and
down) and azimuth (side-to-side)) – 40 mm refractor, 50 mm
refractor, 60 mm refractor, 70 mm refractor and a 76 mm
Newtonian. The PowerSeeker Series is made of the highest
quality materials to ensure stability and durability. All this
adds up to a telescope that gives you a lifetime of pleasure
with a minimal amount of maintenance.
PowerSeeker telescopes carry a two year limited warranty. For details see our website at www.celestron.com.
These telescopes were designed for the First Time Buyer
offering exceptional value. The PowerSeeker series
features a compact and portable design with ample
optical performance to excite any newcomer to the world
of amateur astronomy. In addition, your PowerSeeker
telescope is ideal for terrestrial observations which will
open your eyes with its superb high power viewing.
Your telescope is designed to give you years of fun and
rewarding observations. However, there are a few things to
consider before using your telescope that will ensure your
safety and protect your equipment.
Take time to read through this manual before embarking
on your journey through the Universe. It may take a few
observing sessions to become familiar with your telescope,
so you should keep this manual handy until you have fully
mastered your telescope’s operation. The manual gives
detailed information regarding each step as well as needed
reference material and helpful hints to make your observing
experience simple and pleasurable as possible.
Some of the many standard features of the PowerSeeker include:
• All coated glass optical elements for clear, crisp images.
• Smooth functioning, rigid altazimuth mount with easy pointing to located objects.
• Preassembled aluminum tripod ensures a stable platform.
• Quick and easy no-tool set up.
• CD-ROM “The SkyX” – astronomy software which provides education about the sky and printable sky maps.
• All models can be used terrestrially as well as astronomically with
the standard accessories included.
Warning
•Never look directly at the Sun with the naked eye or with a telescope (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
•Never use your telescope to project an image of the sun onto any surface. Internal heat build-up can damage the telescope and any accessories attached to it.
•Never use an eyepiece solar filter or a Herschel wedge. Internal heat build-
up inside the telescope can cause these devices to crack or break, allowing unfiltered sunlight to pass through to the eye.
•Do not leave the telescope unsupervised, either when children are present or with adults who may not be familiar with the correct operating procedures of your telescope.

Assembly
This section covers the assembly instructions for your
PowerSeeker telescope. Your telescope should be set up
indoor the first time so that it is easy to identify the various
parts and familiarize yourself with the correct assembly
procedure before attempting it outdoor. Each PowerSeeker comes in one box. The pieces in the
box for all models are – optical tube, altazimuth mount,
and “The SkyX” CD-ROM. The 40AZ and 50AZ includes
0.96” accessories – 20 mm eyepiece, 12 mm eyepiece
(50AZ only), 8 mm eyepiece (40AZ only), 4mm eyepiece
(50AZ only), 3x Barlow lens (2x Barlow with 40AZ), and
1.5x erecting eyepiece. The 60AZ, 70AZ and 76AZ
includes 1.25” accessories – 20 mm eyepiece (erect image
for 76AZ), 4 mm eyepiece, 3x Barlow lens, erect image
diagonal for 60AZ.
Setting up the Tripod
1.Remove the tripod from the box (Figure 2-1). The tripod comes preassembled so that the set up is very easy.
Each tripod is different for each model but looks
somewhat similar to the photos shown below.
Figure 2-1
Figure 2-2
2.Stand the tripod upright and pull the tripod legs apart
until each leg is fully extended and then push down
slightly on the tripod leg brace (Figure 2-2). The very top
of the tripod is called the tripod head (AZ mount).
3.Next, we will install the tripod accessory tray (Figure 2-3)
onto the tripod leg brace (center of Figure 2-2).
4.On the bottom of the tripod tray is a screw attached to
the center (except the 40AZ and 50AZ). The screw
attaches into a threaded hole in the center of the tripod
leg brace by turning it clockwise – Note: pull up slightly
on the tripod leg brace to make it easy to attach.
Continue turning the tray until hand tight – don’t over
tighten the tray. The 50AZ is slightly different as you
unthread a small knob in the center of the tray (see
Figure 2-3a) and then put the tray over the threaded
hole and tighten the knob to secure the tray.
5.The tripod is now completely assembled
(Figure 2-4).
6.You can extend the tripod legs to the height you desire. At the lowest level,
the height is about 27” (69 cm) and
extends to about 47” (119 cm). You unlock
the tripod leg lock knobs at the bottom of
each leg (Figure 2-5) by turning them counterclockwise and pull the legs out to the height you want and then lock the
knobs securely. A fully extended tripod looks similar to the image in Figure 2-6.
7.The tripod will be the most rigid and stable at the lower heights.

Attaching the Telescope Tube to the Mount
The telescope optical tube attaches to the altazimuth
mount with the altitude slow motion rod assembly and the
respective knobs for the 60AZ, 70AZ and 76AZ. The 40AZ
and 50AZ attaches directly to the altazimuth mount head.
Before starting, remove the objective lens cap (refractor)
or the front opening cap (Newtonian). To mount the
telescope tube to the mount for the 60AZ, 70AZ and 76AZ:
Figure 2-7
Figure 2-8
1.Remove the protective paper covering the optical tube.
2. Put the telescope optical tube inside the yoke
(altazimuth) mount so that the altitude slow motion rod
assembly is on the same side as the altitude locking
screw (see Figure 1-1). Note that on some telescopes
that the rod may be attached to the telescope optical
tube. If the rod is not attached to the optical tube,
remove the screw from the mechanism (with the
provided tool) shown on the far left of Figure 2-7 and
put the rod in place as shown in Figure 2-7. Then,
put the screw through the hole in the rod and into the
mechanism and tighten it.
3.Thread the altitude locking knob out so the hole is clear
in the eyebolt (see Figure 2-8).
For the 40AZ and 50AZ, take the following steps:
Figure 2-9
4.Put the rod of the assembly through the eyebolt and
then tighten the altitude locking knob – Figure 2-9.
5.Thread the two knobs (one on either side of the mount)
through the top of the mount into the threaded holes in
the optical tube and tighten – Figure 2-7.
Figure 2-10
1. Remove the protective paper covering the optical tube.
2. Place the telescope optical tube on the altazimuth
mount so that the hole in the top of the optical tube
platform lines up with the holes in the mount head –
see Figure 2-11.
3. Insert the altitude locking knob (see center of Figure 2-10)
through the mount head and optical tube platform
(make sure the hole is clear all the way through before
tightening the knob).
Figure 2-11
Moving the Telescope Manually
The PowerSeeker Alt-Az mount is easy to move wherever
you want to point it. For the 60AZ, 70AZ and 76AZ, the up
and down (altitude) is controlled by the altitude locking
knob (Figure 2-12). The side-to-side (azimuth) is controlled
by the azimuth lock (Figure 2-12). When both knobs
are loose, you can find your objects easily (through the
finderscope) and then lock the controls. desired location you want and once there tighten the
altitude locking knob.
Note: Before tightening the altitude locking knob,
the location you are seeking should be located in the
finderscope.
Figure 2-12
For fine adjustments in altitude, you turn the knurled ring
of the altitude slow motion rod (when the altitude lock is
tight) in either direction – see Figure 2-9.
For the 40AZ & 50AZ model, loosen the altitude locking
knob – Figure 2-9 and then move the telescope in the
7
Installing the Diagonal and Eyepiece (Refractor) – 60AZ and 70AZ
The diagonal is a prism that diverts light at a right angle to
the light path of the refractor. This allows you to observe in
a position that is more comfortable than if you had to look
straight through. This diagonal is an erect image model
that corrects the image to be right side up and oriented
correctly left-to-right which is much easier to use for
terrestrial observing. Also, the diagonal can be rotated to
any position which is most favorable for you. To install the
diagonal and eyepiece:
2.Put the chrome barrel end of one of the eyepieces into
the diagonal and tighten the thumb screw. Again, when
doing this make sure the thumbscrew is not protruding
into the diagonal before inserting the eyepiece.
3.The eyepieces can be changed to other focal lengths by
reversing the procedure in step 2 above. Figure 2-13
1.Insert the small barrel of the diagonal into the 1.25”
eyepiece adapter of the focus tube on the refractor
– Figure 2-13. Make sure the two thumbscrews on the
eyepiece adapter do not protrude into the focuser tube
before installation and the plug-up cap is removed from
the eyepiece adapter.
Installing the Diagonal and Eyepiece (Refractor) – 40AZ and 50AZ
The diagonal for the 50AZ is called a star diagonal where
the prism corrects the image to be right side up (erect
image) but the image is reversed right-to-left. The diagonal
and eyepieces are .96” diameter sizes. All steps above are
the same with the 50AZ.
Figure 2-14
Installing the Eyepiece on the Newtonian
The eyepiece (or ocular) is an optical element that magnifies
the image focused by the telescope. Without the eyepiece
it would be impossible to use the telescope visually.
Eyepieces are commonly referred to by focal length and
barrel diameter. The longer focal length (i.e., the larger
the number) the lower the eyepiece magnification (i.e.,
power). Generally, you will use low-to-moderate power
when viewing. For more information on how to determine
power, see the section on “Calculating Magnification”. The
eyepiece fits directly into the focuser of the Newtonian. To
attach the eyepieces:
1. Make sure the thumbscrews are not protruding into
the focuser tube. Then, insert the chrome barrel of the
eyepiece into the focus tube (remove the plug-up cap
of the focuser first) and tighten the thumbscrews – see Figure 2-15.
2. The 20 mm eyepiece is called an erecting eyepiece since
it corrects the image, so it is right side up and corrected
left to right. This makes the telescope useful for
terrestrial viewing.
3. The eyepieces can be changed by reversing the
procedure as described above.
Figure 2-15
Installing and Using the Barlow Lens
Your telescope also comes with a 3x Barlow Lens (2x with
the 40AZ) which triples the magnifying power of each
eyepiece. However, the greatly magnified images should
only be used under ideal conditions – see the Calculating
Magnification section of this manual.
To use the Barlow lens with refractors, remove the diagonal
and insert the Barlow directly into the focuser tube. You
then insert an eyepiece into the Barlow lens for viewing. You can also, insert the diagonal into the Barlow lens and
then use an eyepiece in the diagonal, but you may not be
able to reach focus with all eyepieces. 8
For Newtonian telescopes, insert the Barlow lens directly into
the focuser. Then, insert an eyepiece into the Barlow lens. Note: Start by using a low power eyepiece as it will be
easier to focus.
Figure 2-16
3x Barlow Lens
Installing and Using the 1.5x Erecting Eyepiece – 40AZ and 50AZ
The PowerSeeker 50AZ comes with a 1.5x erecting
eyepiece, primarily for daytime terrestrial viewing. This
eyepiece corrects the image you see in your telescope, so
that it’s both right side up and corrected from left to right. Install and use this eyepiece the same way you do with
the Barlow Lens in the section above. You cannot use the
Barlow lens when using this eyepiece.
When using the erecting eyepiece, the power with various
eyepieces is:
50AZ
50 mm with 20 mm eyepiece = 45x
50 mm with 12 mm eyepiece = 75x
50 mm with 4 mm eyepiece = 225x
40AZ
40 mm with 20 mm eyepiece = 38x
40 mm with 8 mm eyepiece = 94x
Installing the Finderscope (except 40AZ)
To install the finderscope:
1.Locate the finderscope (it will be mounted inside the
finderscope bracket) – see Figures 1-1 and 1-2.
2.Remove the knurled nuts on the threaded posts on the
optical tube – see Figure 2-17.
3.Mount the finderscope bracket by placing it over the
posts protruding from the optical tube and then holding
it in place thread on the knurled nuts and tightening
them down.
4.Note that the finderscope should be oriented so that
the larger diameter lens is facing toward the front of the
optical tube.
5. Remove the lens caps from both ends of the finderscope.
Figure 2-17
Aligning the Finderscope
Use the following steps to align the finderscope:
1.Locate a distant daytime object and center it in a low
power (20 mm) eyepiece in the main telescope.
Objective
2.Look through the finderscope (the eyepiece end of the
Lens
finderscope) and take notice of the position of the
same object.
3.Without moving the main telescope, turn the
Finderscope
adjustment thumb screws located around the
Bracket
finderscope bracket until the crosshairs of the
finderscope are centered on the object chosen with
the main telescope.
