SINCE 1609, when the great Italian scientist Galileo first introduced a rudimentary telescope to astronomy that gave a glimpse of the mysteries lying within the night sky, a fascination to further explore the vast Universe became a constant lure to the curious at heart. By today's standard, that telescope was not much more than ordinary opera glasses. However, that fascination with the mysteries of night skies continued through the ensuing four centuries and triggered immense optic discoveries, culminating in the 21st century, in an ever-growing market not only of professionals but also of serious amateur astronomers and space enthusiasts, young and old alike.

CELESTRON,

OVER

40

YEARS

OF

TELESCOPE

HISTORY.

Today, Southern California-based Celestron has captured the enviable worldwide reputation as a leader in designing, manufacturing and importing high-quality optical products, including computerized and non-computerized telescopes and related accessories, binoculars, spotting scopes and microscopes. The Celestron brand is recognized for its superior optics, outstanding design and innovative technology by serious amateur astronomers.

Celestron was first founded in the 1950's as Valor Electronics, an aerospace electronics firm by Tom Johnson, who, while searching for a suitable telescope for his two young sons, decided to build a telescope from scratch. Starting with a 6-inch reflector, he progressed to building increasingly larger and more sophisticated designs. Tom's hobby soon grew into a full-time business, offering Schmidt-Cassegrain telescopes in 4-inch to 22-inch models.

His immediate challenge was to find a way to efficiently produce the Schmidt corrector plate used in the top-of-the-line catadioptric telescopes

(hybrid of reflector and refractor telescope design).

Although a corrector plate appears flat, it has a

“wavy” surface that is difficult to mass-produce using standard equipment and procedures. By 1970

Celestron designers and engineers announced a revolutionary method of producing Schmidt-Cassegrain telescopes at reasonable cost and in volume. This optical breakthrough was incorporated in the first

Celestron C8. The popularity of the C8 in the consumer marketplace led to the C5 and then to larger versions including an 11-inch and 14-inch telescope.

Today the Celestron product line still features these models and other quality optical products.

NexStar 6 SE

Celestron has experienced impressive growth over the years, since Tom Johnson sold the company in 1980. Between 1980 and 2002 there were a couple of changes in ownership of the company. In 2002, three of Celestron's senior management team purchased the assets of Celestron and initiated a whole new era for Celestron. Under their ownership the company expanded distribution channels and product offerings, and launched the observatory-class CGE Series of computerized equatorial telescopes.

In April of 2005 the SW Technology Corporation acquired the company and provided Celestron access to a supply chain network with state of the art technology and many years of technical and manufacturing experience. Backed with these competitive advantages, Celestron is now able to concentrate its resources towards offering an unprecedented level of customer satisfaction and a wide range of products to the market place.

Throughout the world, Celestron telescopes have become the “telescope of choice” for the consumer that can differentiate between brands. Major colleges and universities worldwide use Celestron telescopes in their astronomy programs.

Moreover, its solid and esteemed reputation in the scientific community has reached NASA, who selected Celestron's C5 telescope as the telescope to be taken on several space shuttle research missions.

Celestron's newest innovative product, SkyScout, was introduced at the 2006 International Consumer Electronics Show in January. It is a handheld, portable celestial viewing device that can identify and/or locate over 6,000 celestial objects, transforming the night sky into your own personal planetarium. It has recently been named the

“Best of Innovations” in the personal electronics category for the

annual showcase of new products at the Consumer Electronics Show.

Today Celestron sells and markets its products worldwide through a variety of specialty retail outlets and international distributors. A privately held company with corporate offices and manufacturing facilities in Torrance, CA, Celestron provides efficient and effective logistical support to large retailers.

What Is A Telescope?

A telescope is a light collector. Its main task is to form the brightest possible optical image of the object on which it is focused. This task is accomplished by the primary optical element, called the “primary” or “objective” inside the telescope’s optical tube. “Primary” usually refers to the mirror in a reflecting telescope while “objective” refers to the main lens of a refracting telescope. The image formed by the primary is then magnified by a removable component called an eyepiece. By using different eyepieces, you can change the magnification and the field of view of what you see through the telescope.

When comparing telescopes, there are a number of characteristics that can help identify their differences. The most common ones are: Light Gathering Power, Limiting Magnitude, Resolution, and Magnification. No matter what types of optical designs you compare, these characteristics provide valuable information that will help you determine what you can expect to see through a telescope.

Light Gathering Power The most important characteristic of a telescope is its light gathering ability. The light gathering capability of a telescope is determined by the diameter of its aperture. The larger the aperture, the more light it collects. When looking at a star, nebula, or galaxy it’s especially important that as much light be gathered as possible.

Fainter celestial objects may be invisible to smaller aperture telescopes. Without enough light, dim objects cannot be seen, no matter how much they might be magnified!

The relationship between a telescope’s light gathering power and the diameter of its lens or mirror is not directly proportional. As the diameter gets larger, the amount of light gathered increases by the square of the diameter. So if you double the diameter of the primary lens, its light gathering ability increases by four times!

Limiting Magnitude Astronomers use a system of “magnitudes” to indicate the brightness of a stellar object. An object is said to have a certain numerical magnitude with 0 (the star Vega ) as the baseline. The larger the magnitude number, the fainter the object. Each magnitude is a difference in brightness by a factor of 2.51 times. For example, a star that is considered 5th magnitude is 100 times fainter than Vega, a zero magnitude star (2.515). The faintest star you can see with your unaided eye is about sixth magnitude (from dark skies) whereas the brightest stars are magnitude zero (or even a negative number).

The faintest star you can see with a telescope (under excellent seeing conditions) is referred to as the “limiting magnitude”. The limiting magnitude of a telescope is directly related to aperture. Larger apertures allow you to see fainter objects. Atmospheric conditions and the visual acuity of the observer will often reduce limiting magnitude.

Resolution The ability of a telescope to render fine detail. Higher resolution lets you see more detail on the surface of a planet or separate stars that are close together. Resolution is measured in terms of degrees of arc (called degrees), minutes of arc (called arcminutes), and seconds of arc (called arcseconds). Thus, something that spans one degree of arc is also 60 arcminutes, or 3600 arcseconds (60 x 60). So, something that is one arcsecond is very small — only

1/3600th of a degree.

Magnification Frequently referred to as “power” and is a function of the focal lengths of both the primary and the eyepiece. The focal length is the distance from the primary lens or mirror to the point where an image is formed.

The eyepiece magnifies the image formed by the primary.

The highest magnification you can reasonably achieve with your telescope is once again determined by the size and light gathering ability of the primary. The practical limit is about 60 times the diameter of the primary in inches. So, an

8” telescope should not be expected to produce reasonable images if the telescope/eyepiece combination produces a magnification greater than 480x. In practice, the amount of magnification that can be used will often be reduced by atmospheric conditions.

Since many astronomical objects are relatively large but faint, moderate magnification and a larger diameter primary to gather light is the best combination for viewing most celestial objects. When looking at stars, high power is of little use since they always look like pinpoints (stars are so far away they can not be resolved as anything other than a pinpoint).

To calculate magnification:

Magnification = Focal Length of Primary in mm / Focal Length of Eyepiece in mm

So, for a 8” telescope using a 25mm eyepiece:

Magnification = 2000/25 = 80 times the power of the unaided eye.

Celestron’s Revolutionary SkyAlign™

Pick three stars, any stars… aligning your telescope is easier and faster than ever. Simply input the date, time and your location (GPS models obtain all this information automatically) and then point the telescope at three bright stars of your choosing. You do not need to know the names of the stars — you could even pick the moon or bright planets! The

NexStar computer system will figure out which stars were chosen and then align the telescope. SkyAlign is standard with NexStar SLT ™ , NexStar ® SE and CPC™ computerized telescopes.

There is no need to point the telescope north or to level the optical tube. The initial position of the telescope is irrelevant. This makes for a fast and very easy method for aligning the telescope.

How does it work?

The NexStar ® software with SkyAlign calculates the angles measured between the objects and then compares them to the known angles between objects. Using this method, the telescope determines what objects were chosen. The display will tell you which three objects you aligned to for confirmation.

StarBright ® XLT — An Optical System Breakthrough!

One of the most important factors in the evaluation of a Schmidt-Cassegrain telescope’s optical system performance is its transmission — the percentage of incoming light that reaches the focal plane. The design of the XLT System accomplishes two crucial objectives – 1. To develop a coating system that is optimized for visual use and, 2. To optimize the coating system and optics for CCD/Photographic imaging.

The StarBright ® XLT High Performance Optical System design consists of:

1. Unique enhanced multi-layer mirror coatings Our mirror coatings are made from precise layers of Aluminum (Al),

SiO2 (Quartz), TiO2 (Titanium Dioxide), and Si02. Reflectivity is fairly flat across the spectrum, optimizing it for both

CCD imaging and visual use.

2. Multi-layer anti-reflective coatings Made from precise layers of MgF2 (Magnesium Fluoride), and HfO2 (Hafnium

Dioxide), which costs nearly $2000 per kilogram, Hafnium results in a wider band pass than Titanium, used in competitive coatings.

3. High Transmission Water White glass Our Schmidt-Cassegrain optical systems with StarBright ® XLT coatings use

Water White glass instead of Soda Lime glass for the corrector lens. Water White glass transmits about 90.5% without anti-reflective coatings. That is 3.5% better transmission than uncoated Soda Lime glass. When Water White glass is used in conjunction with StarBright ® XLT's anti-reflective coatings, the average transmission reaches 97.4% — an

8% improvement!

These three components of our StarBright ® XLT coatings result in one of the finest coatings available. The peak transmission for the systems is 89% at 520 nm. The overall system transmission is 83.5% averaged over the spectrum from 400 to 750 nm.

NexRemote ® Remote Control Software

Celestron has been in the forefront of computerized telescope technology for over two decades. We have taken this expertise one step further by introducing the NexRemote Telescope Remote Control Software. NexRemote allows the user to control their Celestron computerized telescope from a personal computer. Every function that can be done using the telescope’s hand control can now be duplicated remotely from a PC or laptop. This software was developed for Celestron’s telescopes that use the NexStar control system. These include the NexStar ® SLT Series, Advanced Series,

CPC Series and CGE Series (NexRemote ships standard with CPC and CGE Series models).

NexRemote provides full emulation of every aspect of the Celestron Computerized Hand Control plus these additional powerful features:

• NexRemote voice output - Allows you to keep your eyes on the stars instead of the LCD by enabling speech support.

• Select the objects you want to see and the order that you want to see them.

• Create and save custom tours using the NexTour feature.

• Reduce the effect of the laptop screen illumination on your eyes using Night Vision Mode.

• Wireless control of the telescope with optional game pad support.

• Use your personal GPS device to interface with NexRemote ® using NexGPS.

CGE 1400

AN OBSERVATORY CLASS

TELESCOPE

WITH A ROCK SOLID

REPUTATION.

The CGE series is Celestron’s line of observatory class Schmidt-Cassegrain telescopes. Offered in 8", 9 1 / 4 ", 11" and 14" apertures, all are mounted on the state of the art CGE GoTo

German Equatorial mount. The

German Equatorial mount has long been the favored choice of astronomy buffs and astrophotographers because of its stability and portability.

28

The CGE Series features the precision optics of Celestron’s famous Schmidt-

Cassegrain design. All models come standard with our StarBright ® XLT coating for improved light transmission.

CGE Mount Design Advantages

Designed For Portability Set up and transportation of the CGE telescopes is made easy by separating the CGE instruments into individual, easy-to-carry components. The CGE’s optical tube can be quickly removed from its mount, making even the CGE 1400 easily assembled by one person.

Recognized For Superior Stability German Equatorial mounts place the center of gravity directly over the tripod legs making the system extremely stable and virtually eliminates all vibration. An improved Super HD Tripod supports the CGE mount. The tripod is made from the finest cold rolled carbon steel and can be raised to a height of 50". The tripod uses a dual leg support for maximum rigidity with an upper leg brace to provide an outward preload and a lower leg brace providing inward tension.

Easy To Balance Balancing the weight of camera equipment and other visual accessories is accomplished by simply sliding the counterweight for

Right Ascension and moving the optical tube along its dovetail mounting for Declination. No additional weight is needed.

Clearance For Accessories CGE mounts support their tubes at a single contact point allowing the tube to move freely around its polar axis without making contact with the mount. This is useful when adding photographic and CCD instruments that extend from the rear of the telescope.

GPS Compatible All CGE mounted telescopes are compatible with

Celestron’s CN16 GPS accessory (Item #93967).

CGE SERIES FEATURES:

• Carbon Fiber Tube – Strong and lightweight (CGE 925 and 1400 feature aluminum optical tubes)

• Autoguide port, PC port and auxiliary ports located on the electronic pier

• Drive Motors offer smooth, quiet operation and long life

• Precision Bronze Worm Gear, which minimizes total composite error and backlash

• Bearing and Shaft – Stainless steel worm shaft has 0.4375 pitch diameter and is preloaded with two ball bearings; the single piece steel worm is made to minimize run-out, which is a source of periodic error

• No-slip clutch system for pointing precision

• Primary mirror focusing mechanism is supported by two preloaded ball bearings, minimizing the "mirror flop" typical of bushing focusing mechanisms

• GoTo system is precision accurate to 1.5 arcminutes

• 40,000+ object database with 400 user-defined objects

• Hibernate – maintains alignment even while powered down

• Polar alignment routines for northern and southern hemispheres

• Displays only objects above the horizon, also allows for user-defined limits

• Permanent programmable periodic error correction (PEC) – corrects for periodic tracking errors inherent to all worm drives

• NexRemote™ Included

• #11064-XLT is Fastar compatible to reduce astrophotography exposure time

Moon with Saturn • C8 • Photo by Sebastian Voltmer

This optical system is characterized by a large primary mirror at the bottom of the tube which collects light and concentrates it onto a small secondary mirror. The light is then reflected out the side of the tube and into the eyepiece. Best of all, StarHopper Dobsonians are easy to observe with.

The user navigates through the night sky by simply moving the tube up or down, or side to side, by hand.

Celestron StarHoppers use optical quality BK-7 glass. The same high-quality glass used in most binocular prisms and refractor telescope lenses. All

StarHoppers use a roller track bearing on the azimuth surface providing dozens of support points for smooth swivel motion. They also use a variable tension clutch system for proper balance and control in both altitude and azimuth. The 10" & 12" StarHoppers have cooling fans built into the rear cell to decrease cooling times.

STARHOPPER FEATURES:

• Adjustable roller track bearing on the azimuth surface provides a smooth motion

• Variable tension clutch system for proper balance and control in both altitude and azimuth

• Optical quality BK7 annealed glass provides better thermal expansion properties than standard plate glass mirrors

• Built-in cooling fan improves mirror cooling time and reduces damaging tube currents (for StarHopper 10" and 12" models)

• 9-point flotation mirror cell gives equal support of the primary mirror to minimize mirror deflection (for StarHopper 12" model)

• Quick release finder bracket with spring loaded pivot and x-y adjustments

• Carrying handle and eyepiece holder for convenience

CG-5 COMPUTERIZED MOUNT FEATURES

The CG-5 Computerized German Equatorial mount has precision worm gears on both axes for extremely smooth operation. The key element that makes this system the most stable in its class is the heavy-duty tripod with larger and more substantial legs that offer excellent damping characteristics for more stable views.

CG-5 Computerized — GoTo convenience and GPS compatibility for precision accuracy

Couple this solid mount with the included computerized control system to utilize many of the same functions and features — like the NexStar computer control system and an

Autoguider port for long exposure deep sky astrophotography — as Celestron's most advanced GoTo telescopes. GoTo models are also upgradeable to GPS with the optional

CN16 GPS Accessory (#93966) allowing your telescope to pinpoint your position on the earth, the date and time, making the alignment process faster and easier than ever before!

CGE MOUNT FEATURES

Recognized For Superior Stability An improved Super HD Tripod supports the CGE mount. This fully extendable tripod is made from the finest cold rolled carbon steel and can be raised to a height of 50". The tripod uses a dual leg support for maximum rigidity with an upper leg brace to provide an outward preload and a lower leg brace providing inward tension.

CGE Equatorial Mounts Can Easily be Balanced on Both Axes Balancing the weight of camera equipment and other visual accessories is accomplished by simply sliding the counterweight for Right Ascension and moving the optical tube along its dovetail mounting for

Declination. This means that no additional weight needs to be added to balance the telescope when additional accessories are added.

Clearance For Accessories CGE mounts support their tubes at a single contact point allowing the tube to move freely around its polar axis without making contact with the telescope’s mount. This is particularly useful when adding photographic and CCD instruments that extend from the rear of the telescopes.

GPS Compatible All CGE mounts are compatible with Celestron’s CN16 GPS accessory

(Item #93967). Combine the GPS and built-in Hibernate mode and these mounts will keep track and remember their exact location and time without the need to re-enter the information into the computerized hand control.

The Mount and Tripod

To a large extent, a telescope is only as good as its tripod and mount. A telescope magnifies everything, including vibration. That’s why many telescopes with good optics are rendered useless when supplied on an inexpensively made mount. Since you’ll be using a mount’s controls to track the slow and steady apparent movement of the stars, a suitable mount’s adjustments should be smooth, yet precise.

Altazimuth vs. Equatorial

There are two basic types of mounts: Altazimuth (Alt-Azimuth) and Equatorial. Altazimuth mounts are the simplest type of mount with two motions: altitude (up and down/vertical) and azimuth (side-to-side/horizontal). Good Altazimuth mounts will have slow motion cable controls to make precise adjustments, which aid in keeping tracking motion smooth.

These type of mounts are good for terrestrial observing and for scanning the sky at lower power but are not advised for deep sky photography.

Both Altazimuth and Equatorial mounts can track the stars sufficiently for visual use, however, only equatorials can be used for long exposure astrophotography. Since Altazimuth mounts are not aligned with the Earth’s axis, they must use both axes to track an object. With

Altazimuth mounts you will be able to accurately track an object centered in the field of view, however over time all the other stars in the field will appear to rotate around the center of the field. This is hardly noticeable in an eyepiece, but is obvious on film.

Altazimuth Advantages

• Easy to set-up and use

• Least expensive type of mount

• Ideal for terrestrial observing

Altazimuth Disadvantages

• Cannot be used for long exposure photography

• Non-computerized models cannot track stars and planets

On an Equatorial mounting, the two axes are perpendicular to each other as they are on an Altazimuth mount. But on an

Equatorial mounting, the left-to-right axis has been tilted so that it is parallel to the Earth’s axis instead of at the horizon. On an

Equatorial mount, only the axis that is parallel to the Earth’s axis, needs to be rotated. On an Altazimuth mount, BOTH axes must be moved.

If you would like to do long exposure photography, the telescope must be mounted on an equatorial mount. Some Celestron telescopes that are on

Altazimuth mountings can be tilted up (with the use of an equatorial wedge) to orient the azimuth axis parallel to the Earth’s axis.

Equatorial Advantages

• Best for long exposure photography

• Easy to use visually because only one axis movement compensates for Earth’s rotation

• Setting circles on non-computerized models help locate astronomical objects

Equatorial Disadvantages

• Set-up is more extensive because of polar alignment requirements

• Not suitable for terrestrial use

Do you want a GoTo computerized telescope?

Many of Celestron’s telescopes are computerized “GoTo” telescopes. GoTo capability is very useful for the novice who needs assistance in finding objects in the night sky. Since there is a large database of celestial objects, it is unnecessary to refer to star charts to identify objects.

Once the telescope is properly aligned and an object is selected, the telescope will automatically “go to” the object. GoTo equipped Celestron telescopes include both altazimuth and equatorial models. Even without GoTo, many Celestron equatorial scopes have manual setting circles that allow you to find objects in the sky with the help of a good star map.

There are a number of factors to consider when selecting a particular telescope. These factors will usually depend on your individual requirements including cost, portability, versatility, usability and appearance. You should also consider how you plan to use the instrument both now and in the future. Most important, consider your budget and portability requirements, and select a telescope with the largest aperture possible.

Types of Telescopes

REFRACTOR TELESCOPE

A refractor telescope uses a lens as the primary. The lens at the front of the telescope bends the light passing through it until it comes to a single point called the “focal plane”.

The long, thin tubes of refractor telescopes look much the same as those Galileo used centuries ago. High quality optical glass and multi-coatings provide today’s sky watchers views

Galileo never dreamed of. The refractor type of telescope is very popular with individuals who want mechanical simplicity, rugged reliability and ease of use. Because the focal length is limited by the length of the tube, refractor telescopes become quite bulky and expensive beyond a four inch aperture. This limits the light gathering properties of refractor telescopes, but it is an excellent choice for beginners and those who prefer simple operation and versatility. Refractor telescopes are also a popular choice because of their unobstructed view, high contrast and good definition.

Refractor Advantages

• Easy to set-up and use

• Simple and reliable design

• Little or no maintenance

• Excellent for lunar, planetary and binary star observing especially in larger apertures

• Good for terrestrial viewing

• High contrast images with no secondary mirror or diagonal obstruction

• Color correction is good in achromatic designs and excellent in apochromatic and fluorite designs

• Sealed optical tube reduces image-degrading air currents and protects optics

• Objective lens is permanently mounted and aligned

Refractor Disadvantages

• More expensive per inch of aperture than Newtonians or Catadioptrics

• Heavier, longer and bulkier than equivalent aperture Newtonians and Catadioptrics

• The cost and size factors limit the practical maximum size primary to smaller apertures

• Some color aberration in achromatic designs (doublet)

NEWTONIAN REFLECTOR TELESCOPE

A Newtonian reflector uses a single concave mirror as its primary. Light enters the tube traveling to the mirror at the back end. Light is then “bent” forward in the tube to a single point, its focal plane. A flat mirror called a “diagonal” intercepts the light and points it out the side of the tube at right angles to the tube through the eyepiece. The eyepiece is placed there for easy viewing.

Newtonian Reflector telescopes replace heavy lenses with mirrors to collect and focus the light, providing much more light gathering power for the money. You can have focal lengths up to 1000mm and still enjoy a telescope that is relatively compact and portable. Newtonian

Reflector telescopes do require more care and maintenance because the primary mirror is exposed to air and dust. However, this small drawback does not hamper this type of telescope’s popularity with those who want an economical telescope that can still resolve faint, distant objects.

Newtonian reflectors produce a “right-side-up image” but the image will appear rotated based on the location of the eyepiece holder in relation to the ground. Newtonian reflectors are best for astronomical use where right-side-up does not matter.

Newtonian Advantages

• Lowest cost per inch of aperture compared to

Refractors and Catadioptrics since mirrors can be produced at less cost than lenses in medium to large apertures

• Reasonably compact and portable up to focal lengths of 1000mm

• Excellent for faint deep sky objects such as remote galaxies, nebulae and star clusters due to the generally fast focal ratios (f/4 to f/8)

• Adequate for lunar and planetary work

• Good for deep sky astrophotography (but not as convenient and more difficult to use than Catadioptrics)

• Free of color aberration due to the use of a primary mirror

Newtonian Disadvantages

• Generally not suited for terrestrial applications

• Slight light loss due to secondary (diagonal) obstruction when compared with Refractors

CATADIOPTRIC TELESCOPE

Catadioptrics use a combination of mirrors and lenses to “fold” (reflect) the light path and form an image. There are two popular designs: the Schmidt-Cassegrain and the Maksutov-

Cassegrain. In a Schmidt-Cassegrain, the light enters through a thin aspheric Schmidt correcting lens. It then strikes the spherical primary mirror. It is reflected back up the tube and intercepted by a small secondary mirror which reflects the light out an opening in the rear of the instrument where the image is formed at the eyepiece. Catadioptrics are the most popular and most modern type of telescope optical design and are marketed throughout the world in

3.5” and larger apertures.

Catadioptric telescopes combine the practical advantages of lenses and mirrors while eliminating their disadvantages. They offer the clarity and contrast of refractors with the low aberration of reflectors. Catadioptrics have an average focal ratio of f/10 which is wide enough for all types of photography. They are also easier to maintain because all optical elements are solidly mounted and rigidly collimated. Catadioptric telescopes provide the best possible combination of light gathering power, long focal length, portability and affordability.

Schmidt-Cassegrain Advantages

• Best all-purpose telescope design

• Combines the optical advantages of both lenses and mirrors while eliminating their disadvantages

• Excellent optics and razor sharp images over a wide field

• Excellent for deep sky observing and astrophotography

• Very good for lunar, planetary and binary star observing

• Excellent for terrestrial viewing and photography

• Focal ratio generally around f/10

• Closed tube design reduces image-degrading air currents

• Extremely compact and portable

• Easy to use

• Durable and virtually maintenance free

• Large apertures at reasonable cost and less expensive than equivalent aperture refractors

• Most versatile type of telescope

• More accessories available than with other types of telescopes

• Best near focus capability of any type of telescope

Schmidt-Cassegrain Disadvantages

• More expensive than Newtonians of equal aperture

• Slight light loss due to secondary mirror obstruction compared to refractors

MAKSUTOV–CASSEGRAIN TELESCOPE

The Maksutov-Cassegrain is similar to the

Schmidt-Cassegrain with essentially the same advantages and disadvantages. It uses a thick meniscus correcting lens with a strong curvature and a secondary mirror that is usually an aluminized spot on the corrector. The Maksutov secondary mirror is typically smaller than the

Schmidt’s which gives it slightly better resolution for planetary observing.

Advantages of Maksutov-Cassegrain Compared to Schmidt-Cassegrain

• Smaller secondary obstruction results in a slight increase in planetary detail and contrast

• Less expensive to manufacture

• Longer focal lengths resulting in higher magnifications for planetary viewing

Disadvantages of Maksutov-Cassegrain Compared to Schmidt-Cassegrain

• Slightly heavier because of the thick meniscus correcting lens

• Increased time to reach thermal stability in larger apertures over 90mm

• Longer focal lengths resulting in smaller field of views
