Introduction • 1 INTRODU CTION Welcome to the Celestron world of amateur astronomy! For more than a quarter of a century, Celestron has provided amateur astronomers with the tools needed to explore the universe. The Celestron CM-1100 and CM-1400 continues in this proud tradition combining large aperture optics with ease of use and portability.
2 • Introduction This manual is designed to instruct you in the proper use of your Celestron CM-1100 telescope. The instructions are for assembly, initial use, long term operation, and maintenance. There are seven major sections to the manual. The first section covers the proper procedure for setting up your Celestron CM- 1100 telescope.
Introduction • 3 DREN ARE PRESENT OR ADULTS WHO MAY NOT BE FAMILIAR WITH THE CORRECT OPERATING PROCEDURES OF YOUR TELESCOPE. NEVER POINT YOUR TELESCOPE AT THE SUN UNLESS YOU HAVE THE PROPER SOLAR FILTER. WHEN USING YOUR TELESCOPE WITH THE CORRECT SOLAR FILTER, ALWAYS COVER THE FINDER.
4 • Assembling Your CM-1100 ASSEMBLING YOUR CM-1 100 This section covers the assembly instructions for your Celestron CM-1100 telescope. The Celestron CM-1100 should be set up indoors the first time so that it is easy to identify the various parts and familiarize yourself with the correct assembly procedure before attempting it outdoors.
Assembling Your CM-1100 • 5 Figure 2-1 1. Optical Tube 2. Finderscope 3. Star Diagonal 4. Eyepiece 5. Polar Axis Finderscope 6. Drive Control Electronics 7. Hand Control 8. Tripod 9. Center Leg Brace 10. Counterweight 11. Counterweight Bar 12. R.A. Clutch Knob 13.
6 • Assembling Your CM-1100 Setting Up the Tripod The tripod legs attach to a central column which together form the tripod to which the equatorial mount attaches. The tripod comes with two leg support brackets; a collapsible one that is already attached to the lower legs and a removable one that must be attached.
Assembling Your CM-1100 • 7 Before the equatorial mount head can be installed, the central column with the electronics module must be attached to the tripod. To attach the central column: 1 Position the central column so that the electronics module is right side up (see Figure 2-4).
8 • Assembling Your CM-1100 After the tripod is set up, you are ready to attach the equatorial mount. The equatorial mount is the platform to which the telescope attaches and allows you to move the telescope in right acsension and declination.
Assembling Your CM-1100 • 9 To properly balance the telescope, the mount comes with a counterweight bar and one counterweight (the CM-1400 comes with two counterweights). The counterweight bar is located in the same box as the Equatorial Mount Head — in a cutout along the bottom of the shipping box.
10 • Assembling Your CM-1100 The telescope attaches to the mount via a dovetail slide bar which is mounted along the bottom of the telescope. Before you attach the optical tube, make sure that the declination and right ascension clutch knobs are tight.
Assembling Your CM-1100 • 11 The visual back is the accessory that allows you to attach all visual accesso- ries to the telescope. To attach the visual back: 1. Remove the plastic cover on the rear cell. 2. Place the knurled slip ring on the visual back over the threads on the rear cell.
12 • Assembling Your CM-1100 The eyepiece, or ocular, is an optical element that magnifies the image focused by the telescope. The ocular(s) fit into either the visual back directly, the star diagonal, or the Erect Image Diagonal (purchased separately).
Assembling Your CM-1100 • 13 The CM-1100 telescope come with a 9x50 finderscope used to help you locate and center objects in the main field of your telescope. To accomplish this, the finder has a built-in cross-hair reticle that shows the optical center of the finderscope.
14 • Assembling Your CM-1100 To aid in polar aligning the mount, your telescope comes standard with a Polar Housing Finder. It installs directly on top of the polar housing of the mount. To install the Polar Finder: 1 . Locate the Polar Finder assembly.
Assembling Your CM-1100 • 15 Once set up, you need to point your telescope at various portions of the sky to observe different objects. To make rough adjustments, loosen the R.A. and DEC clutch knobs slightly and move the telescope in the desired direction.
16 • Assembling Your CM-1100 In order for the clock drive to track accurately, the telescope’s axis of rotation must be parallel to the Earth’s axis of rotation, a process known as polar alignment. Polar alignment is achieved NOT NOT NOT NOT NOT by moving the telescope in R.
Assembling Your CM-1100 • 17 To eliminate undue stress on the mount, the telescope should be properly balanced around the polar axis. Proper balancing is crucial for accurate tracking. To balance the mount: 1 . Verify that the telescope securing knobs on the telescope mounting platform are tight.
18 • Assembling Your CM-1100 Although the telescope does not track in declination, the telescope should also be balanced in this axis to prevent any sudden motions when the DEC clutch knob is loose. To balance the telescope in DEC: 1 . Loosen the R.
Assembling Your CM-1100 • 19 Because of the Celestron CM-1100's size and weight, you should ALWAYS ALWAYS ALWAYS ALWAYS ALWAYS remove the telescope from the mount when moving the telescope. To do so: 1 . Take the telescope off of the mount and return it to its shipping box.
20 • Assembling Your CM-1100 Below is pertinent technical information on your Celestron CM-1100 telescope that you may find useful. OPTICAL TUBE: OPTICAL TUBE: OPTICAL TUBE: OPTICAL TUBE: OPTICAL TU.
Assembling Your CM-1100 • 21 TRIPOD: TRIPOD: TRIPOD: TRIPOD: TRIPOD: • All machined aluminum • Semi-pier Tripod Design • Fixed hieght Tripod with dual leg support • Tripod legs are 48.
22 • Telescope Basics TELESCOPE BASICS Once your telescope is fully assembled, you are ready for your first look. This section deals with some of the basics of telescope operation. The image orientation changes depending on how the eyepiece is inserted into the telescope.
Telescope Basics • 2 3 The Celestron CM-1100 focusing mechanism controls the primary mirror which is mounted on a ring which slides back and forth on the primary baffle tube. The focusing knob, which moves the primary mirror, is on the rear cell of the telescope just right of the star diagonal and eyepiece.
24 • Telescope Basics Your Celestron CM-1100 can be used for both terrestrial and astronomical photography. Your Celestron CM-1100 has a fixed aperture and, as a result, a fixed f/ratio. To properly expose your subjects photographically you need to set your shutter speed accordingly.
Telescope Basics • 2 5 With the telescope fully assembled and all the accessories attached, you are ready for your first look. Your first look should be done in the daytime when it is easier to locate the locking clutches. This will help to familiarize you with your telescope, thus making it easier to use at night.
26 • Telescope Basics Nighttime Observing Looking at objects in the sky is quite different than looking at objects on Earth. For one, many objects seen in the daytime are easy to see with the naked eye and can be located in the telescope by using landmarks.
Telescope Basics • 2 7 You can change the power of your Celestron CM-1100 telescope just by changing the eyepiece (ocular). To determine the magnification of your Celestron CM-1100, simply divide the focal length of the telescope by the focal length of the eyepiece used.
28 • Astronomy Basics ASTRONOMY BASICS The following section deals with observational astronomy in general. It in- cludes information on the night sky, polar alignment, and using your telescope for astronomical observing.
Astronomy Basics • 29 The daily motion of the Sun across the sky is familiar to even the most casual observer. This daily trek is not the Sun moving as early astronomers thought, but the result of the Earth ’ s rotation.
30 • Astronomy Basics In order for the telescope to track the stars, you must meet two criteria. First, you need a drive motor that moves at the same rate as the stars. The Celestron CM-1100 comes standard with a built-in drive motor designed specifically for this purpose.
Astronomy Basics • 31 In each hemisphere, there is a point in the sky around which all the other stars appear to rotate. These points are called the celestial poles and are named for the hemisphere in which they reside. For example, in the northern hemisphere all stars move around the north celestial pole.
32 • Astronomy Basics Latitude Scales The easiest way to polar align a telescope is with a latitude scale. Unlike other methods that require you to find the celestial pole by identifying certain stars near it, this method works off of a known constant to determine how high the polar axis should be pointed.
Astronomy Basics • 33 Pointing at Polaris This method utilizes Polaris as a guidepost to the celestial pole. Since Polaris is less than a degree from the celestial pole, you can simply point the polar axis of your telescope at Polaris. Although this is by no means perfect alignment, it does get you within one degree.
34 • Astronomy Basics The Polar Axis Finder The Polar Axis Finder is designed to minimize polar alignment time while maintaining maximum accuracy. The installation of this accessory is de- scribed in the section on “ Installing the Polar Axis Finder.
Astronomy Basics • 35 Declination Drift This method of polar alignment allows you to get the most accurate alignment on the celestial pole and is required if you want to do long exposure deep-sky astrophotography through the telescope. The declination drift method requires that you monitor the drift of selected guide stars.
36 • Astronomy Basics Before you can use the setting circles to find objects in the sky, you need to align both the R.A. and DEC setting circles. In order to align the setting circle, you need to know the names of a few of the brightest stars in the sky.
Using the Drive • 37 Figure 5-1 The CI-700 electronic console. Powering Up the Drive USING THE DRIVE The drive system uses a 5.625 diameter bronze gear with 180 teeth for incred- ibly accurate tracking. One of the most unique features of the drive is the Periodic Error Correction (PEC) function.
38 • Using the Drive This function allows you to select the speed at which the motor moves when corrections are made via the hand controller. Once the drive is activated, the default setting is .3 times sidereal rate. Press the Speed button to change the guiding rate.
Using the Drive • 39 RATE The BC (Backlash Correction) function allows you to eliminate the backlash in the DEC motor when changing directions (i.e., from north to south or vice versa). Here ’ s how it works. Each time you change the direction of the telescope in declination, the motor speeds up momentarily to take up any slack.
40 • Using the Drive 12 V DC 5. Press the “ PEC ” button once to activate the mode. The LED will flash once a second for 5 seconds indicating you have five seconds to get back to the eyepiece and begin guiding before it begins recording. The .3x guiding rate is best for this function.
Using the Drive • 41 The Hand Controller When using your Celestron CM-1100 in the southern hemisphere, there is a need to reverse the motors. Changing from northern hemisphere to southern hemisphere requires changing the polarity of the drive motor by changing the settings of the dip switches on the electronics board.
42 • Using the Drive R.A./DEC Reverse As mentioned previously, the direction a particular button moves the mount varies depending on the telescope ’ s orientation (i.
Celestial Observing • 43 CELESTIAL OBSERVING With your telescope set up, you are ready to use it for observing. This section covers visual observing of both solar system and deep-sky objects. In the night sky, the Moon is a prime target for your first look because it is extremely bright and easy to find.
44 • Celestial Observing Although overlooked by many amateur astronomers, solar observation is both rewarding and fun. However, because the Sun is so bright, special precautions must be taken when observing our star so as not to damage your eyes or your telescope.
Celestial Observing • 45 Deep-sky objects are simply those objects outside the boundaries of our solar system. They include star clusters, planetary nebulae, diffuse nebulae, double stars, and other galaxies outside our own Milky Way. The Celestron Sky Maps (#93722) can help you locate the brightest deep-sky objects.
46 • Celestial Observing Star Hopping Another way to find deep-sky objects is by star hopping. Star hopping is done by using bright stars to “ guide ” you to an object. Here are the directions for two popular objects. The Andromeda Galaxy, M31, is an easy target.
Celestial Observing • 47 Star hopping may take some getting used to since you can see more stars through the finder than you can see with the naked eye. And, some objects are not visible in the finder. One such object is M57, the famed Ring Nebula. Here ’ s how to find it: 1.
48 • Celestial Observing Viewing conditions affect what you can see through your CM-1100 telescope during an observing session. Conditions include transparency, sky illumina- tion, and seeing. Understanding viewing conditions and the effect they have on observing will help you get the most out of your CM-1100 telescope.
Celestial Observing • 49 Type 2 seeing conditions do move as quickly as Type 1, though the image is quite blurry. Fine detail is lost and the contrast is low for extended objects. Stars are spread out and not sharp. The source of Type 2 seeing is the lower atmosphere, most likely heat waves from the ground or buildings.
50 • Celestial Photography CELESTIAL PHOTOGRAPHY After looking at the night sky for awhile you may want to try photographing it. Several forms of celestial photography are possible with your Celestron CM- 1100 telescope.
Celestial Photography • 5 1 Short exposure prime focus photography is the best way to begin recording celestial objects. It is done with the camera attached to the telescope without an eyepiece or camera lens in place. To attach your camera you need the Celestron T-Adapter (#93633-A) and a T-Ring for your specific camera (i.
52 • Celestial Photography The exposure times listed here should be used as a starting point. Always make exposures that are longer and shorter than the recommended time. Also, try bracketing your exposures, taking a few photos at each shutter speed.
Celestial Photography • 5 3 The easiest way to enter the realm of deep-sky, long exposure astrophotogra- phy is via the piggyback method. Piggyback photography is done with a camera and its normal lens riding on top of the telescope.
54 • Celestial Photography The exposure time depends on the film being used. However, five minutes is usually a good starting point. With slower films, like 100 ISO, you can expose as long as 45 minutes. With faster films, like 1600 ISO, you really shouldn ’ t expose more than 5 to 10 minutes.
Celestial Photography • 5 5 This form of celestial photography is designed for objects with small angular sizes, primarily the Moon and planets. Planets, although physically quite large, appear small in angular size because of their great distances.
56 • Celestial Photography The following table lists exposures for eyepiece projection with a 10mm eyepiece. All exposure times are listed in seconds or fractions of a second. The exposure times listed here should be used as a starting point. Always make exposures that are longer and shorter than the recommended time.
Celestial Photography • 5 7 This is the last form of celestial photography to be attempted after others have been mastered. It is intended primarily for deep-sky objects, that is objects outside our solar system which includes star clusters, nebulae, and galaxies.
58 • Celestial Photography When getting started, use fast films to record as much detail in the shortest possible time. Here are proven recommendations: • Ektar 1000 (color print) • Konica 3200 .
Celestial Photography • 5 9 Fastar Lens Assembly Option – Using your CM-1400 telescope at f/2.1 with optional PixCel CCD Camera Only the CM-1400 is equipped with a removable secondary mirror that allows you to convert your f/11 telescope into an f/2.
60 • Celestial Photography The F/# stands for the ratio between the focal length and the diameter of the light gathering element. A C14 optical tube has a focal length of 154 inches and a diameter of 14 inches. This makes the system an f/11, (focal length divided by diameter).
Celestial Photography • 6 1 When imaging some objects like planetary nebula (for example M57, the Ring Nebula) and small galaxies (M104, the Sombrero Galaxy), larger image scale is needed to resolve finer detail. These objects are better shot at f/7 or even f/ 11.
62 • Celestial Photography 2 3 1 4 5 3 6 8 9 7 13 12 14 11 10 15 18 16 17 19 10 9 20 24 21 20 22 19 10 23 Planetary or Lunar-- f/20 is a great way to image the planets and features on the moon. With the PixCel CCD camera and optional Color Filter Wheel, it is easy to take tri-color images of planets also.
Telescope Maintenance • 6 3 TELESCOPE MAINTENANCE While your CM-1100 telescope requires little maintenance, there are a few things to remember that will ensure your telescope performs at its best. Occasionally, dust and/or moisture may build up on the corrector plate of your telescope.
64 • Telescope Maintenance spheric distortion. Turn your telescope drive on so that you won ’ t have to manually track the star. Or, if your are not using the clock drive, use Polaris. Its position relative to the celestial pole means that it moves very little thus eliminating the need to manually track it.
Telescope Maintenance • 6 5 6 Once the star image is in the center of the field of view, check to see if the rings are concentric. If the central obstruction is still skewed in the same direction, then continue turning the screw(s) in the same direction.
66 • Optional Accessories OPTIONAL ACCESSORIES The following is a partial list of optional accessories available for your Celestron CM-1100/1400. You will find that additional accessories enhance your viewing pleasure and expand the usefulness of your telescope.
Optional Accessories • 67 prism arrangement that, in addition to producing correctly oriented images, allows you to look into the telescope at a 45 ° angle, a desirable arrangement for terrestrial viewing.
68 • Optional Accessories in the main telescope. Flashlight (#93592) - The LED flashlight uses a red LED to allow reading star maps without ruining your night vision. The LED flashlight is small, only 6 inches long, and weighs in at a mere 3 ounces.
Optional Accessories • 69 prime focus long-exposure astrophotography. It makes guiding easier and exposures shorter. Sky Maps (#93722) - When learning the night sky, the Celestron Sky Maps offer the ideal solution. The maps include all the constellations and brighter deep-sky objects.
70 • The Messier Catalog THE MESSIER CATALOG The Messier Catalog, compiled by Charles Messier, was the first extensive listing of star clusters and nebulae. Messier ’ s primary observational purpose was to discover comets. He compiled this list so that others searching for comets would not be confused by these objects.
