Congratulations on your purchase of an Ambassador telescope. The Ambassador 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.

These telescopes were designed for the discriminating buyer. The brass finish of the Ambassador series, along with the attractive mahogany wood used for the tripod, were designed to be a decorative piece in the home, office, or anywhere to show off its vintage style. In addition, your telescope is ideal for terrestrial observing.

Ambassador telescopes carry a two year limited warranty. For details see our website at www.celestron.com

Some of the standard features of the Ambassador include:

• Fully coated glass optical elements for clear, crisp images.

• Brass optical tube with brass fittings. Note that minor surface imperfections are normal with this metal.

• Smooth functioning, rigid altazimuth mount with easy pointing to locate objects.

• Standard accessories supplied for terrestrial observing.

• Can be used for casual astronomical observing. 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.

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 adults who

may not be familiar with the correct operating procedures of your telescope.

This section covers the assembly instructions for your Ambassador telescope. Since some parts are heavy (especially on the 80mm model), and you need to be careful not to scratch the brass finish, it is suggested that you have two people work together to assemble the telescope. The various parts for the telescope are wrapped with protective materials and please remove these carefully.

Each Ambassador comes in one box. The pieces in the box for all models are – optical tube with altazimuth mount attached, three tripod legs, tripod accessory tray/brace, instruction manual.

In addition, the 80mm model has an eyepiece, erect image diagonal, erect image finderscope, and finderscope brackets with mounting hardware.

You will need the following tools – small Phillips head screwdriver and two small crescent wrenches or open- end/box-end wrenches of 16mm (5/8”).

1. Remove the three tripod legs - Figure 2-1 from the carton. The 50mm telescope legs are similar to the

80mm model but are slightly shorter in length and width.

2. Loosen (turn counterclockwise) the tripod leg lock knob near the botto m of the tr ipod – Figur e 2-2, and

then pull the center wood piece out about 10” (254mm) which will make th e assembly easier. Then tighten the tripod leg lock knob. Do the same for the other two tripod legs. You can see what the top of the tripod leg looks like in Figure 2-3.

3. Next, we will install the tripod accessory tray/brace to the tripod leg hinges -- Figure 2-4 shows an

image of the tripod leg hinge. Note that the hinge for the 80mm model (shown) has five holes as shown but the 50mm has a long slot to use. The hinge on all three legs will face inward.

4. The accessory tray is shown in Figure 2-5 along with three wing nuts and three screws with washers.

The image shows the screws and washers removed from the wing nuts (they come with the screws and washers attached so they don’t get lost but they need to be removed for assembly).

5. The accessory tray needs to be face up as shown and the wing nuts will be on top with the screw (with

washer attached) threaded into the wing nuts from the bottom of the accessory tray. You should insert the wing nuts and screws/washers initially into the 2 from the tripod leg. On the 50mm model attach the screws/washers about mid way in the slot on the tripod hinge. You can relocate the position of the mounting of the accessory tray to the hinge at a later time if you desire.

Figure 2-1 Figure 2-2 Figure 2-3 Figure 2-4

hole on the accessory tray (on the 80mm model)

6. Figure 2-6 shows one tripod leg hinge ready to attach to the accessory tray. You can hand tighten the

screw with washer initially but once all three leg hinges are attached to the tray, then tighten with a Phillips head screwdriver for the screw while holding the wing nuts with your other hand.

7. Once all the hinges are attached and tightened to the accessory tray, it will look like Figure 2-7.

Figure 2-5 Figure 2-6 Figure 2-7

8. You can extend the tripod legs to the height you desire. At the lowest level the height of th e 50mm model is about 35” (89cm) and extends to about 60” (152cm). For the 80mm model, the lowest level height is about 43” (109cm) and extends to about 72 ” (183 cm). You un lock the tripod leg lo ck kno b s at the bottom of each leg (Figure 2-2) by turning them counterclockwise and pull the legs out to the height you want and then lock the knobs securely.

9. The tripod will be the most rigid and stable at lower heights but you should adjust the height for comfortable usage.

10. On the 80mm model you can use the holes in the accessory tray for placing additional (optional) 1.25” eyepieces.

The telescope optical tube comes attached to the altazimuth mount. This assembly will now be attached to the tripod which was just assembled. This is where two people come in real handy as the tripod legs are agile and can move about easily when lining up the bolts that fit between the top o f the tripod legs an d throug h the lower part of the mount. Images are shown using the 80mm model but the 50mm is similar unless noted.

Figure 2-8 Figure 2-9 Figure 2-10 Figure 2-11

1. Lay the tripod legs on the floor.

2. Lay the optical tube and mount between two of the tripod legs as shown in Figure 2-8.

3. The holes of the mount (near the bottom –Figure 2-9) will fit between the legs of the tripod and

attached with the bolt assembly of the tripod legs – see Figure 2-10.

4. Remove the bolt and washers from each leg assembly. Note that the 50mm does not have washers

on the inside of the tripod legs.

5. Put one ear of the mount between a tripod leg. Now, insert one of the bolts with washer through

one side of the leg and through the ear of the mount and out the other side of the leg. Make sure all the washers are placed as they were originally on the tripod legs. Now tighten the bolts with wrenches.

6. When all tripod leg bolt assemblies are attached to the mount, it will appear as in Figure 2-11.

The Ambassador mount is easy to move wherever you want to point it.

The up and down (altitude) is controlled by the altitude lock (Figure 2-12). Loosen the altitude lock by turning it counterclockwise and when at the desired location tighten the lock by turning it clockwise. Note: Before tightening the altitude lock all the way on the 80mm, the target

object you are seeking should be located in the finderscope.

Figure 2-12

The side-to-side (azimuth) motion is controlled by the azimuth locking knob (Figure 2-13). Loosen the azimuth locking knob by turning it counterclockwise and when at the desired location tighten the lock.

Figure 2-13

When both knobs are loose you can find your objects easily and then lock the controls. The images are shown for the 50mm and the 80mm are similar.

Note: If the up/down (altitude) motion appears too stiff or too loose, you can adjust the tension. To do this, you can tighten or loosen the round knobs (one on each side of the mount directly across from each other). Make sure the locks in both axes are tight to begin. Hold both round knob s at the same time and turn them slightly to loosen or tighten them. Then release the altitude lock and check the tension. Keep adjusting the knobs until the tension is satisfactory to you. The round knob is located directly above the altitude lock as seen in Figure 2-12a.

A finderscope is a very small telescope mounted on the main telescope to make it easier to locate objects.

To install the finderscope:

1. Figure 2-14 shows the finderscope (at top) and the brackets with

mounting screws.

2. Mount the brackets in the holes on the optical tube (Figure 2-15) with

the thumbscrews and tighten. The mounted brackets are shown in Figure 2-16.

3. Remove the lens caps from both ends of the Finderscope.

4. Put the finderscope inside the mounting brackets with the larger

diameter lens (objective end) facing towards the front (objective lens) of the optical tube. You will need to back up the screws in the brackets so the finderscope will fit inside them.

5. The Finderscope should be fit into the brackets where the thumbscrews

can be tightened inside the small grooves in the finderscope. Then, hand tighten the thumbscrews. Figure 2-14

Figure 2-15 Figure 2-16 Figure 2-17

To align the finderscope with the main telescope:

1. Remove the front lens cap of the telescope and both caps from the finderscope. Locate a distant

daytime object (at least ¼ mile/0.4km away) and center it in the main telescope.

2. Look through the finderscope (the eyepiece end of the finderscope which has the smaller diameter

lens) and take notice of the position of the same object.

3. Without moving the main telescope, turn the thumbscrews of the finderscope brackets until the

crosshairs of the finderscope are centered on the object chosen with the main telescope. This may take a number of attempts to get it properly centered as you loosen one and tighten another of the thumbscrews of each bracket.

4. If the image through the finderscope is not sharp (out of focus), you will need to adjust the

finderscope so you can obtain a sharp focus through it. Locate the ring on the finderscope (it is between the objective lens and the finderscope bracket) and turn it counterclockwise to loosen it a few turns. Then turn the front objective piece in or out until a sharp focus is achieved. Lastly, tighten the ring.

The diagonal is a prism that diverts the light at a 45° angle to the light path of the telescope. This allows you to observe in a position that is more comfortable th an if you had to look straig ht thro ugh. This diagon al 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:

1. Remove the cap at the rear of the telescope by unthreading it counterclockwise – Figure 2-18.

2. Insert the small barrel of the diagonal into the rear opening of the telescope. Make sure the

thumbscrew on the telescope does not protrude into the opening before installation. Once the diagonal is inserted, tighten the thumbscrew to hold it in place – Figure 2-19.

3. Put the barrel of the eyepiece into the diagonal and tighten the thumbscrew of the diagonal to hold

the eyepiece in place and tighten the thumbscrew – Figure 2-20. Again, when doing this make sure the thumbscrew is not protruding into the diagonal before inserting the eyepiece.

4. The standard eyepiece can be changed to other optional eyepieces (for lower or higher power) by

reversing the procedure in step 3 above.

Figure 2-18 Figure 2-19 Figure 2-20

A telescope is an instrument that collects and focuses light. The nature of the optical design determines how the light is focused. The refractor telescope uses lenses in its optical design.

Developed in the early 1600s, the refractor is the oldest telescope design. It derives its name from the method it uses to focus incoming light rays. The refractor uses a lens to bend or refract incoming light rays, hence the name (see Figure 3-1). Early designs used single element lenses. However, the single lens acts like a prism and breaks light down into the colors of the rainbow, a phenomenon known as chromatic aberration. To get around this problem, a two-element lens, known as an achromat, was introduced. Each element has a different index of refraction allowing two different wavelengths of light to be focused at the same point. Most two-element lenses, usually made of crown and flint glasses, are corrected for red and green light. Blue light may still be focused at a slightly different point.

For the 80mm Ambassador, simply turn the focus knob (located in front of the diagonal – see Figure 3-2). Turning the knob clockwise allows you to focus on an object that is farther than the one you are currently observing. Turning the knob counterclockwise from you allows you to focus on an object closer than the one you are currently observing.

For the 50mm Ambassador, simply turn the large knurled ring shown in Figure 3-3. Turning the focus ring counterclockwise allows you to focus on an object that is closer than the one you are currently observing. Turning the focus ring clockwise allows you to focus on an object farther than the one you are cu rrently observing. Remember to remove the front objective cap prior to observing through the telescope.

Note: If you wear corrective lenses (specifically glasses), you may want to remove them when observing

with the telescope. If you have astigmatism, corrective lenses must be worn at all times.

The Ambassador 50AZ model has a fixed eyepiece which has a magnification (power) of 16x. This model was designed for terrestrial observing and this power is good for all around general usage.

The Ambassador 80AZ model comes standard with a 25mm eyepiece which has a magnification (power) of 32x. You can purchase optional eyepieces (not with a brass finish) to give you higher or lower powers. You can see what is available by looking on the Celestron website.

You can change the power of your 80mm telescope just by changing the eyepiece (ocular). To determine the magnification of your telescope, simply divide the focal length of the telescope by the focal length of the eyepiece used. In equation format, the formula looks like this:

Focal Length of Telescope (mm) Magnification = ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ Focal Length of Eyepiece (mm)

Let’s say, for example, you are using the 25mm eyepiece that came with your telescope. To determine the magnification you divide the focal length of your telescope (the Ambassador 80AZ for this example has a focal length of 800mm) by the focal length of the eyepiece, 25mm. Dividing 800 by 25 yields a magnification of 32x.

Although the power is variable, each instrument under average skies has a limit to the highest useful magnification. The general rule is that 60 power can be used for every inch of aperture. For example, the Ambassador 80AZ is 3.2 inches in diameter. Multiplying 3.1 by 60 gives a maximum useful magnification of 186 power. Although this is the maximum useful magnification, most observing is done at low power.

Note on Using High Powers – Higher powers are used mainly for lunar and sometimes planetary observing where you can greatly enlarge the image, but remember that the contrast and brightness will be very low due to the high magnification. For the brightest images with the highest contrast levels, use lower powers.

GGeenneerraall OObbsseerrvviinngg HHiinnttss

When using any optical instrument, there are a few things to remember to ensure you get the best possible image.

• Never look through window glass. Glass found in household windows is optically imperfect, and as

a result, may vary in thickness from one part of a window to the next. This incon sistency can and will affect the ability to focus your telescope. In most cases you will not be able to achieve a truly sharp image, while in some cases you may actually see a double image.

• Never look across or over objects that are producing heat waves. This includes asphalt parking lots

on hot summer days or building rooftops.

• Hazy skies, fog, and mist can also make it difficult to focus when viewing terrestrially. The amount

of detail seen under these conditions is greatly reduced.

• If you wear corrective lenses (specifically glasses), you may want to remove them when observing

with an eyepiece attached to the telescope. If you have astigmatism, corrective lenses must be worn at all times.

The Ambassador telescopes were designed mainly for terrestrial observing. However, if you have an interest in looking up in the sky, you can observe the Moon and planets quite easily. If you have an interest especially with the 80mm model) to locate some deep sky objects (galaxies, nebulae, or clusters), you will have to find them by “star hopping”. Star hopping is a technique that assists in locating deep sky objects and you can find out how to do it by searching the web for information.

A limitation of astronomical observing is that the Ambassador telescopes have a limited range of sky you can observe in (objects cannot be observed closer than about 30° from the zenith with the 50mm model and about 45° with the 80mm model). This limitation is due to the vintage mechanical design of the altazimuth mount.

Lunar Observing Hints

To increase contrast and bring out detail on the lunar surface, use optional filters. A yellow filter works well at improving contrast while a neutral density or polarizing filter will reduce overall surface brightness and glare.

OObbsseerrvviinngg tthhee PPllaanneettss

Other fascinating targets include the five naked eye planets. You can see Venus go through its lunar-like phases. Mars can reveal a host of surface detail and one, if not both, of its polar caps. You will be able to see the cloud belts of Jupiter and the great Red Spot (if it is visible at the time you are observing). In addition, you will also be able to see the moons of Jupiter as they orbit the giant planet. Saturn, with its beautiful rings, is easily visible at moderate power

Often, it is tempting to look at the Moon when it is fu ll. At this time, the face we see is fully illuminated and its light can be overpowering. In addition, little or no contrast can be seen during this phase.

One of the best times to observe the Moon is during its partial phases (around the time of first or third quarter). Long sh adows reveal a great amount of detail on the lunar surface. At low power you will be able to see most of the lunar disk at one time. Change to optional eyepieces for higher power (magnification) with the 80mm model to focus in on a smaller area.

Planetary Observing Hints

• Remember that atmospheric conditions are usually the limiting factor on how much planetary detail

will be visible. So, avoid observing the planets when they are low on the horizon or when they are directly over a source of radiating heat, such as a rooftop or chimney.

• To increase contrast and bring out detail on the planetary surface, try using optional Celestron

eyepiece filters.

While your telescope requires little maintenance, there are a few things to remember that will ensure your telescope performs at its best.

CCaarree aanndd CClleeaanniinngg ooff tthhee MMeecchhaanniiccaall PPaarrttss

To keep the brass finish looking clean and bright, use brass polishing material. For the wood on the tripod, use furniture polish. Follow the instructions given with the polishing materials.

CCaarree aanndd CClleeaanniinngg ooff tthhee OOppttiiccss

Occasionally, dust and/or moisture may build up on the objective lens or eyepiece of the telescope. Special care should be taken when cleaning any instrument so as not to damage the optics.

If dust has built up on the optics, remove it with a brush (made of camel’s hair) or a can of pressurized air. Spray at an angle to the glass surface for approximately two to four seconds. Then, use an optical cleaning solution and white tissue paper to remove any remaining debris. Apply the solution to the tissu e and th en apply th e tissue p aper to the op tics. Low pressure strokes should go from the center of the lens (or mirror) to the outer portion. Do NOT rub in circles!

You can use a commercially made lens cleaner or mix your own. A good cleaning solution is isopropyl alcohol mixed with distilled water. The solution should be 60% isopropyl alcohol and 40% distilled water. Or, liquid dish soap diluted with water (a couple of drops per one quart of water) can be used.

To minimize the need to clean your telescope, replace all lens covers once you have finished using it. Since the cells are NOT sealed, the covers should be placed over the openings when not in use. This will pr event contaminants from entering the optical tube. Internal adjustments and cleaning should be done only by the Celestron repair department. If your telescope is in need of internal cleaning, please call the factory for a return authorization number and price quote.

Dieser Abschnitt enthält die Anleitung zum Zusammenbau des Ambassador-Teleskops. Da einige Teile sehr schwer sind (besonders beim 80-mm-Modell) und Sie aufpassen müssen, damit die Messingoberfläche nicht zerkratzt wird, wird empfohlen, dass das Teleskop von zwei Personen zusammengebaut wird. Die verschiedenen Teile des Teleskops sind mit Schutzmaterial eingewickelt. Bitte entfernen Sie dieses Material vorsichtig.

Das Ambassador-Teleskop ist immer in einem Karton verpackt. Die Teile im Karton für alle Modelle sind: optischer Tubus mit angebrachter Altazimut-Montierung, drei Stativbeine, Stativzubehörablage/Strebe, Bedienungsanleitung.

Außerdem wird das 80-mm-Modell mit einem Okular, Zenitspiegel für aufrechtes Bild, Sucherfernrohr für aufrechtes Bild und Sucherfernrohrhalterung mit Befestigungsteilen geliefert.

Sie benötigen die folgenden Hilfsmittel: einen kleinen Kreuzschlitzschraubendreher und zwei kleine Rollgabelschlüssel (Engländer) oder Gabelschlüssel/Ringschlüssel von 16 mm (5/8 Zoll) Größe

AAuuffbbaauu ddeess SSttaattiivvss

1. Nehmen Sie die drei Stativbeine aus dem Karton (Abb. 2-1). Die Beine des 50-mm-Teleskops ähneln denen des 80-mm-Modells, haben je doch eine kürzere Länge und Breite.

2. Lösen Sie (durch Drehen gegen den Uhrzeigersinn) den Feststellknopf des Stativbeins in der Nähe der Unterseite des Stativs (Abb. 2-2) und ziehen Sie dann das mittlere Holzstück ca. 254 mm (10 Zoll) heraus. Das erleichtert den Zusammenbau. Drehen Sie dann den Feststellknopf des Stativbeins fest. Machen Sie das Gleiche für die anderen beiden Stativbeine. In Abb. 2-3 ist gezeigt, wie der obere Teil des Stativbeins aussieht.

3. Als Nächstes installieren wir die Stativzubehörablage/Strebe an den Stativbein-Scharnieren. Das Stativbein-Scharnier ist in Abb. 2-4 gezeigt. Beachten Sie, dass das Scharnier für das 80-mm-Modell (abgebildet) fünf Löcher hat, wie gezeigt, und dass das 50-mm-Modell einen langen Schlitz aufweist. Das Scharnier aller drei Beine ist nach innen gerichtet.

4. Die Zubehörablage ist in Abb. 2-5 gezeigt, zusammen mit drei Flügelmuttern und drei Schrauben mit Unterlegscheiben. Das Bild zeigt die Schrauben und Unterlegscheiben von den Flügelmuttern entfernt (sie werden mit angelegten Schrauben und Unterlegscheiben geliefert, so dass sie nicht verloren gehen, aber sie müssen zum Zusammenbau entfernt werden).

5. Die Zubehörablage muss wie in der Abbildung gezeigt nach oben zeigen, und die Flügelmuttern sind oben, so dass die Schrauben (mit angelegter Unterlegscheibe) von der Unterseite der Zubehörablage in die Flügelmuttern eingeschraubt werden. Sie sollten die Flügelmuttern und Schrauben/Unterlegscheiben zuerst in das zweite Loch an der Zubehörablage (am 80-mm-Modell) vom Stativbein einstecken. Am 50-mm-Modell werden die Schrauben/Unterlegscheiben ungefähr in der Mitte des Schlitzes am Stativscharnier befestigt. Sie können die Position der Zubehörablage am Scharnier bei Bedarf später verstellen.

6. Abb. 2-6 zeigt ein Stativbeinscharnier, das zur Befestigung an der Zubehörablage bereit ist. Sie können die Schraube mit der Unterlegscheibe zuerst von Hand anziehen, aber wenn alle drei Beinscharniere an der Ablage befestigt sind, ziehen Sie die Schraube mit einem entsprechenden Kreuzschlitzschraubendreher fest, während Sie die Flügelmuttern mit der anderen Hand festhalten.

7. Nachdem alle Scharniere an der Zubehörablage befestigt und angezogen wurden, sehen sie aus wie in Abb. 2-7.

8. Die Beine des Stativs können auf die gewünschte Höhe ausgezogen werden. Die geringste Höhe beim 50-mm-Modell ist ca. 89 cm (35 Zoll). Mit voll ausgefahrenen Beinen hat das Stativ eine Höhe von ca. 150 cm (60 Zoll). Die geringste Höhe beim 80-mm-Modell ist ca. 109 cm (43 Zoll). Mit voll ausgefahrenen Beinen hat das Stativ eine Höhe von ca. 183 cm (72 Zoll). Entriegeln Sie die Feststellknöpfe unten an jedem Stativbein (Abb. 2-2), indem Sie sie gegen den Uhrzeigersinn drehen, und ziehen Sie die Beine auf die gewünschte Höhe heraus. Arretieren Sie dann die Feststellknöpfe wieder.

9. Das Stativ ist in den geringeren Höhen am steifsten und stabilsten, aber Sie sollten die Höhe so wählen, dass Sie bequem damit arbeiten können.

10. Beim 80-mm-Modell können Sie die Öffnungen in der Zubehörablage zur Ablage von zusätzlichen (optionalen) 1,25-Zoll-O k ul aren verwenden.

Der optische Tubus des Teleskops wird an der Altazimut-Montierung angebracht geliefert. Diese Einheit wird jetzt an das Stativ, das Sie soeben zusammengebaut haben, montiert. Dieses Verfahren wird am besten von zwei Personen durchgeführt, denn die Stativbeine sind beweglich und können sich verschieben, wenn die Schrauben, die zwischen den Oberteil der Stativbeine und durch den Unterteil der Montierung gehen, ausgerichtet werden. Die Bilder zeigen das 80-mm-Modell, aber das 50-mm-Modell ist ähnlich, außer wenn auf Unterschiede hingewiesen wird.

1. Legen Sie die Stativbeine auf den Boden.

2. Legen Sie den optischen Tubus und die Montierung zwischen zwei der Stativbeine (siehe Abb. 2-8).

3. Die Löcher der Montierung (in der Nähe der Unterseite, siehe Abb. 2-9) passen zwischen die Stativbeine und werden mit der Schraubeneinheit der Stativbeine befestigt (siehe Abb. 2-10).

4. Entfernen Sie die Schrauben und Unterlegscheiben von jeder Beineinheit. Beim 50-mm-Modell gibt es keine Unterlegscheiben an der Innenseite der Stativbeine.

5. Setzen Sie eine Ecke der Montierung zwischen ein Stativbein. Stecken Sie jetzt eine der Schrauben mit Unterlegscheibe durch eine Seite des Beins und durch die Ecke der Montierung, bis sie auf der anderen Seite des Beins austritt. Achten Sie darauf, dass alle Unterlegscheiben so angelegt sind, wie sie ursprünglich an den Stativbeinen aufgesetzt waren. Ziehen Sie jetzt die Schrauben mit Schraubenschlüsseln fest.

6. Wenn alle Stativbein-Schraubeneinheiten an der Montierung befestigt sind, sieht es so aus wie in Abb. 2-11.
