Assembling Your Telescope
To set up the tripod, locate the equatorial mount (20), the tripod legs (13), and the tripod mounting head (11).
1. Slide the two top portions of each tripod leg around the sides of each flange on the tripod mounting head (11).
Make sure that the tripod center support brace hinges (15) are located on the inside of the each leg.
2. Slide the provided screws through the tripod leg and flange,
until the screw extends out the other side (see Figure 1-2).
Slide the washer and the nut over the screw and tighten. This
can be left slightly loose, to allow for positioning the legs
later, when attaching the accessory tray.
Tripod
Mounting Head
(11)
You are now ready to attach the tripod accessory tray.
3. The tripod tray fits over the holes in the tripod's center
support brace (15). Insert the winged bolts through the holes
in each of the tripod center support braces and thread them
into the holes in the accessory tray. Tighten all bolts to ensure
proper stability to the mount.
Attaching the Equatorial Mount
Figure 1-2
1. Place the base of the equatorial mount (20) into the hole on the top of the tripod mounting head (11).
2. Rotate the equatorial mount until the declination axis (where the counterweight bar (18) goes) is positioned over
one of the tripod legs.
3. Attach the mount to the tripod by threading the equatorial head mounting screw (12) into the bottom of the
mount
Before attaching the optical tube, the counterweight and slow motion controls should be added to the mount:
1. Thread the counterweight bar (18) clockwise into the declination axis of the equatorial mount. Slide the
counterweight (17) over the counterweight bar and lock down the screw on the side of the counterweight.

2. Locate the declination slow motion control (9) and attach to the mount by tightening the set screw on the control
cable. See Figure 1-3. The set screw should be tightened down hard on the flat surface of the cable holder after
backing off the cable about 1/4" from being fully engaged. This method helps ensure there is no slippage when
using the cable.
3. Locate the right ascension slow motion control (19) and attach it the same way as
the declination cable was attached.
Attaching the Optical Tube
You are now ready to put the telescope optical tube (2) onto the equatorial mount
(20).
1. Remove the two locking wing nuts from the telescope optical tube (2).
2. Place the telescope tube on the mount so that the treaded post at the bottom of the
tube's mounting platform (21) go through the holes on the top of the mount.
3. Thread a wing nut onto the end of the threaded posts and tighten to secure the
tube to the mount.
Attaching the Accessories
Figure 1-3
Your telescope comes with the following optical accessories:
•
•
•
•
20mm eyepiece 1¼"
4mm eyepiece 1¼ "
3x Barlow Lens 1¼"
1.5x Erect Image Eyepiece 1¼"
1. Remove the caps from the focuser (5).
2. Place the chrome barrel end of the eyepiece into the star diagonal (see Figure 1-
4). Lock it into place with the thumb screw on the side of the star diagonal.
3. The PowerSeeker 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. Without this
eyepiece, the image you see is reversed from left to right, when using the
standard diagonal. To use the erecting eyepiece, remove the diagonal and
insert the erecting eyepiece directly into the focuser. Then use a low power
eyepiece such as the 20mm, inserting it directly into the erecting eyepiece. See
Figure 1-5.
Figure 1-4
4. Your telescope also comes with a 3x Barlow lens which triples the
magnifying power of each eyepiece (see Magnification section of the
manual). To use the barlow lens, remove the diagonal and insert the
barlow lens directly into the focuser. Then start by using the low power
eyepiece such as the 20mm, and insert it either directly into the barlow
lens or into the diagonal. See Figure 1-5.
Figure 1-5
Attaching the Finderscope
1. Remove the two small, silver thumbscrews located on top of the telescope tube. See Figure 1-6.
2. Place the finderscope bracket (4) over the two holes in the telescope tube, lining up the holes on the
finderscope bracket with those in the telescope tube.
3. Insert the thumbscrews through the finderscope bracket and thread them into the telescope tube.

Aligning the Finderscope
1. Locate a distant daytime object and center it in a low power eyepiece in the main telescope.
2. Look through the finderscope and take notice of the position of the same object.
3. Without moving the main telescope, turn the adjustment thumb screws located
around the finderscope bracket until the crosshairs of the finder are centered on the
alignment object.
Finding Objects
In order to use the equatorial mount's setting circles, the mount must first be aligned with the
earth's axis of rotation.
Figure 1-6
1. Turn the latitude adjustment screw (10) located at the rear of the mount to adjust the angle of the mount.
Look at the latitude scale and move the mount to the latitude of your location. This only has to be done
once unless you take the telescope to a different location. For example, Los Angeles, California is located
at about 34º. If you do not know your latitude, it can be
found on most road atlases of your area.
Declination
Setting Circle
Right Ascension
Setting Circle
To change the direction your telescope is pointing:
2. To move the telescope in declination (north/south) there
are two options. For large and quick movements, loosen the
declination locking screw and manually move the
telescope, then tighten the knob when you are near the
position you want. For very small movements and fine
adjustments, use the declination slow motion control (9).
The declination cable has a range of about 30°. Do not try
to force movement when the declination cable has
reached the stop.
Latitude
Scale
Figure 1-7
3. To move the telescope in right ascension (east/west) there are two options. For large and quick movements,
loosen the right ascension locking screw (located above the setting circle) and manually move the telescope,
then tighten the screw when you are near the position you want. For very small movements and fine
adjustments, use the right ascension slow motion control (19).
The telescope should be properly balanced in order for it to move smoothly in both axes. Proper balance is essential
if using an optional motor drive for accurate tracking.
4. To balance the right ascension axis, move the counterweight bar so it is parallel (horizontal) to the ground.
Slowly release the right ascension locking screw and see if the optical tube moves. If the optical tube
moves, then slide the counterweight up or down the counterweight bar until the optical tube remains
stationary in the parallel position to the ground. When this happens, make sure the counterweight lock
(located on the tip of the counterweight bar) is tight.
Focusing
1. Once you have found an object in the telescope, turn the focusing knob until the image is sharp.
2. To focus on an object that is nearer than your current target, turn the focusing knob toward the eyepiece
(i.e., so that the focusing tube moves away from the front of the telescope). For more distant objects, turn
the focusing knob in the opposite direction.
3. To achieve a truly sharp focus, never look through glass windows or across objects that produce heat waves,
such as asphalt parking lots.

Image Orientation
1. When observing with a diagonal, the image will be right side up, but reversed from left to right.
2. When observing straight through, with the eyepiece inserted directly into the telescope, the image will
be inverted. Also, the image in the finderscope is inverted.
Magnification
The magnification (or power) of a telescope varies depending upon the focal length of the eyepiece being used and
the focal length of the telescope.
The PowerSeeker 60EQ telescope has a focal length of 900mm and comes with a 20mm 1¼" eyepiece. To calculate
magnification, use the following formula, in which FL = focal length:
FL (telescope) in mm
FL (eyepiece) in mm
Magnification =
Therefore, if you use the 20mm eyepiece your magnification is 900/20 = 45x. The same formula can be applied to
any of your eyepieces.
Important!
Magnification through any telescope has its limits. These limits are determined by the laws of optics and the nature
of the human eye. Most of your viewing will be done in the range of 35x to 120x. Higher powers are used mainly
for lunar and sometimes planetary observing where you can greatly enlarge the image and the atmospheric conditions
are near perfect. The images at extremely high powers magnify the image, but remember that the contrast will be
very low due to the high magnification. For the brightest images with the most contrast, start by using the lower
power eyepiece with a smaller image scale.
The following magnification levels can be achieved when using the standard eyepieces in conjunction with the 3x
Barlow lens:
Eyepiece Magnification
Mag. with 1.5x
Erecting Eyepiece
68x
Mag. with 3x Barlow
Lens
135x
675x
20mm
4mm
45x
225x
338x
TELESCOPE MAINTENANCE
With proper care, your telescope should rarely need any maintenance work. To maintain your telescope in the best
possible condition, observe the follow suggestions:
1. When your telescope isn’t in use, replace all lens covers to keep dust and contaminants off the optical surfaces.
2. A small amount of dust on any optical surface isn’t a problem and doesn’t need to be removed. If the dust
builds up, then use a can of compressed air and a camels hair brush to remove the dust. To remove fingerprints
or other contaminants, use an optical cleaning kit or the Celestron Lens Pen (#93575).
3. If the inside of the objective lens needs cleaning, it should be done by a professional. Either have your
instrument serviced by a telescope repair facility or return it to the factory for servicing.
