CELESTRON PowerSeeker

INTRODUCTION
Congratulations on your purchase and welcome to the Celestron world of amateur astronomy. Some of the terms and parts described in these instructions may be new to you, so a few commonly used terms you’ll want to be familiar with are defined below.
Equatorial mount –­ a type of mounting that allows the telescope to be aligned with the earth’s axis in order to track the motion of the sky.
Focal length – the distance from the optical center of the lens to the point where the incoming light rays converge, creating a clear, focused image. Objective lens – the front lens of the telescope. It gathers incoming light to create a sharply focused image.
Refracting telescope – a long, thin tube where light passes in a straight line from the front objective lens directly to the eyepiece at the opposite end of the tube.
First, you need to take the time to familiarize yourself with the parts of your PowerSeeker telescope, then assemble it, following the easy instructions provided. Next, read over the operating instructions and become familiar with how your telescope works, to prepare for hours of viewing enjoyment.

CAUTION: READ THIS SECTION BEFORE USING YOUR TELESCOPE

Your PowerSeeker telescope is designed to give you hours of fun and rewarding observing. However, there are a few things to be aware of before using your telescope that will ensure your safety and protect your equipment.

NEVER LOOK DIRECTLY AT THE SUN WITH THE NAKED EYE OR WITH A TELESCOPE. NEVER POINT YOUR TELESCOPE AT THE SUN UNLESS YOU’RE USING 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, OR USE AN EYEPIECE SOLAR FILTER OR A HERSCHEL WEDGE. INTERNAL HEAT BUILD-UP CAN DAMAGE THE TELESCOPE AND/OR ANY ACCESSORIES THAT MAY BE ATTACHED TO IT.

NEVER LEAVE YOUR TELESCOPE UNSUPERVISED, ESPECIALLY WHEN CHILDREN ARE PRESENT. THIS ALSO HOLDS TRUE FOR ADULTS WHO MAY NOT BE FAMILIAR WITH THE CORRECT OPERATING PROCEDURES FOR YOUR TELESCOPE.

ALWAYS COVER THE FINDERSCOPE WHEN USING YOUR TELESCOPE WITH THE CORRECT SOLAR FILTER. ALTHOUGH SMALL IN APERTURE, THIS INSTRUMENT HAS ENOUGH LIGHT-GATHERING POWER TO CAUSE PERMANENT AND IRREVERSIBLE EYE DAMAGE. THE IMAGE PROJECTED BY THE FINDERSCOPE IS HOT ENOUGH TO BURN SKIN OR CLOTHING.

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 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.

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

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 it to secure the tube to the mount.

Attaching the Accessories

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 thumbscrew 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 sides up and correct 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.
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.

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 finder scope 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 thumbscrews 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.

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.

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 a stop.

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 on 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 the magnification, use the following formula, in which FL = focal length:

Magnification = FL (telescope) in mm
FL (eyepiece) in mm

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:

TELESCOPE MAINTENANCE

With proper care, your telescope should rarely need any maintenance work. To maintain your telescope in the best possible condition, observe the following 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 camel’s 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 has your instrument serviced by a telescope repair facility or return it to the factory for servicing.
