Features of this Telescope’s Optical System . . .
  • Advanced Coma-Free catadioptric designed to emulate the optical performance of a Ritchey-Chrétien telescope: The traditional two-mirror Ritchey-Chrétien (R-C) design uses two large hyperbolic primary and secondary mirrors to produce images that are free from coma over a wide field. Because of this wide coma-free field and a relatively fast focal ratio, the Ritchey-Chrétien design is particularly well suited to astrophotography. The R-C is the design of choice for most of the major professional observatory telescopes built in the last half-century. For example, the Hubble Space Telescope and the twin 10-meter Keck telescopes in Hawaii are Ritchey-Chrétiens.
        However, because of the complexity of fabricating and testing a large aperture hyperbolic mirror (just ask the people who built the initially-flawed, but not discovered until it was in space, Hubble Space Telescope), traditional large aperture two-mirror Ritchey-Chrétiens are very expensive to manufacture and purchase, too expensive for many amateur astronomers.
        To emulate the coma-free performance of a true R-C telescope, while keeping the cost very much within reason, each Meade Advanced Coma-Free (ACF) catadioptric optical system uses a full aperture aspheric corrector lens in conjunction with a simple spherical primary mirror. This creates a two-element primary mirror system that performs like an R-C’s single hyperbolic primary mirror from the optical point of view of the system’s secondary mirror. The hyperbolic secondary mirror itself is mounted directly on the rear of the corrector lens, rather than in the traditional R-C’s conventional spider vane assembly. This eliminates the image-degrading diffraction spikes of the secondary mirror support structure visible in commercial R-C scope images. The result is R-C-class coma-free wide-field performance, at only a fraction the cost of most true R-C systems.
        The corrector-modified design would itself be expensive to fabricate were it not for Meade’s more than a quarter-century of experience making Schmidt-Cassegrain correctors, which are in the same optical family as the corrector needed for the coma-free design of the ACF scopes. An additional benefit of the full aperture corrector in the ACF design is slightly better correction for astigmatism than the traditional R-C design.
        In addition, the ACF design, due to its front corrector plate, is a closed tube design. This keeps the primary optical components protected from dust, moisture and other contaminants that might fall on the optical surfaces of the primary and secondary mirrors as can happen with the traditional open-tube R-C design.
        While the ACF scopes may not be traditional R-C designs, their performance is R-C-like in all important characteristics. A review in Sky & Telescope magazine of the ground-breaking predecessor of the Meade ACF optics said the bottom line is that the optics do “indeed perform like a Ritchey-Chrétien.” Another such review, in Astronomy magazine said, “This scope delivers Ritchey-Chrétien-like performance at a fraction of the cost.”

    • Low thermal expansion mirrors: The primary and secondary mirrors are made of low thermal expansion Pyrex to limit any possible focal length change as the temperature drops. This reduces the possibility of the focus changing during critical through-the-scope CCD imaging.

    • Oversized primary mirrors: The diameter of the primary mirror of each ACF scope is larger than the diameter of the corrector lens at the front of its optical tube that admits the light. For example, the primary mirror of the 8” scope is actually 8.25” in diameter, compared to the 8” diameter of the corrector lens. Oversizing the primary mirror in this way gives you a wider fully-illuminated field than a conventional catadioptric scope whose corrector and primary mirror are the same size. The result is a gain of 5% to 8% more off-axis light available to your eye or camera, depending on the telescope model.

    • Fully multicoated UHTC (Ultra High Transmission Coatings) optics: The primary and secondary mirrors are vacuum-coated with aluminum, enhanced with multiple layers of titanium dioxide and silicon dioxide for increased reflectivity. A final layer of durable silicon monoxide (quartz) assures long life.
          A series of anti-reflective coatings of aluminum oxide, titanium dioxide, and magnesium fluoride are vacuum-deposited on both sides of the full aperture corrector plate. These antireflection multicoatings provide a high 99.8% light transmission per surface, versus a per-surface transmission of 98.7% for standard single-layer coatings. Overall light throughput (the amount of light collected by the objective lens that actually reaches your eye or camera) is approximately 89% at the focal plane.
          UHTC multicoatings provide a 15% increase in light throughput compared with standard single-layer coatings. . For example, they effectively add the equivalent of a little more than four-tenths of an inch of extra light-gathering aperture to the performance of the 6” optical system – but with no increase in actual size or weight. The UHTC multicoatings also improve contrast, for lunar and planetary images that appear sharper and more crisply defined.

    • Fully baffled optics: A cylindrical baffle around the secondary mirror, in combination with the cylindrical baffle tube projecting from the center of the primary mirror, prevents stray off-axis light from reaching the image plane. In addition, a series of field stops machined into the inner surface of the central baffle tube effectively eliminates undesirable light which might reflect from the inside surface of the tube. The result of these baffle systems is improved contrast in lunar, planetary, and deep space observing alike.

This Meade LS 6” LightSwitch telescope has:

• LightSwitch technology for hands-free/eyes-free automatic alignment on the sky
• Advanced Coma-Free optics rival professional Ritchey-Chrétien scope performance
• built-in 640 x 480 pixel color CCD camera with 8° field
• Astronomer Inside multimedia output with built-in speaker and video output
• UHTC optical multicoatings
• AutoStar III computer control with 100,000 object database

    This Meade 6” LS ACF LightSwitch catadioptric telescope aligns itself on the skies automatically to make astronomy easy. You don't have to know Polaris from the Pleiades, or Albireo from Zubeneschamali, to align the scope on the sky each night. You just have to turn it on. As Sky & Telescope said when naming it a Sky & Telescope Hot Product for 2010, “Meade’s LightSwitch technology adds a new level of automation to the set up and use of Go To telescopes.” Here’s a link to a rave review of the Meade LightSwitch go-to technology in the December 2010 issue of Sky & Telescope.

    The Meade LS LightSwitch Technology uses a GPS (Global Positioning System) receiver, proprietary LNT (Level North Technology), an AutoStar III computer, and an ECLIPS (Electronically Controlled Locate Identify Position System) CCD camera to make the scope amazingly simple to set up and operate. Simply turn on your Meade LS. First the GPS receiver automatically determines where and when you are on Earth from the signals it receives from a network of Earth-orbiting satellites. Then the LNT system automatically levels the optical tube and points it north. Next, the AutoStar III computer automatically points the scope at two alignment stars. And finally the wide-field ECLIPS CCD camera images those alignment stars and automatically centers them for you to refine your celestial alignment.

    You never have to look through the eyepiece or finder, or touch any button other than the on/off switch, to have your Meade LS perfectly align itself on the skies, ready to find 100,000 celestial objects for you at the touch of a button. You can be observing dozens and dozens of deep space objects like a seasoned observer your first night out.

    This Meade 6” LS ACF catadioptric brings the image quality of a professional observatory to your back yard, at the lowest price ever for optics of this quality. Its Advanced Coma-Free optics have a flat, coma-free field that is visibly similar to that of the Ritchey-Chrétien design optics used in most professional observatory telescopes and the Hubble Space Telescope, but at a mere fraction the cost of a true Ritchey-Chrétien.

    Remember that the best telescope for you is not always the biggest scope money can buy. It’s the scope you use most often. And with its superb balance of sensible aperture, reasonable weight, unique features, and low price, you will find yourself using the highly portable 6” Meade LS ACF with Advanced Coma-Free UHTC optics a lot. Here’s a link to a recent video review on the LS6 that talks about just how easy the scope is to use. The Meade LS – a Sky & Telescope Hot Product for 2010 – may well be the perfect telescope for you . . . for life.

This Meade LS Telescope’s Optical System . . .

  • Advanced Coma-Free catadioptric designed to emulate the optical performance of a Ritchey-Chrétien telescope: 6” aperture (1524mm focal length f/10). Oversized Pyrex primary mirror. Schott water white glass front corrector lens. Fully-multicoated UHTC (Ultra High Transmission Coatings) optics for the highest possible image brightness. Aluminum tube construction with glare-stop baffling. Guaranteed diffraction-limited performance. The scope has a standard Schmidt-Cassegrain rear cell thread, allowing the use of most SCT accessories manufactured over the past 30 years. For more details, click on the “optics” icon above.

  • Finderscope: The Meade LS finderscope is a SmartFinder non-magnifying red dot finder for object centering and star-hopping when using the AutoStar III hand control manually to stroll through the heavens without using the computer to guide you. This straight-through wide-field red dot finder allows easy non-magnified views of the sky, with a projected red dot of light showing exactly where the scope is pointed at all times.

  • Star diagonal: 1.25” 90° multicoated prism type.

  • Eyepiece: 1.25” 26mm Meade Super Plössl (58x). The eyepiece field of view is 0.89°, nearly 80% wider than the full Moon, for expansive lunar and deep space views.

  • ECLIPS CCD camera: The ECLIPS (Electronically Controlled Locate Identify Position System) color CCD camera is mounted under the optical tube. Its wide-angle short focal length lens is aimed parallel to the tube and takes 8° wide 640 x 480 pixel panoramas of the sky centered on the object at which the scope is aimed. The ECLIPS camera forms a vital part of the LightSwitch automatic sky alignment system, by imaging the stars that the scope points at during its alignment sequence and centering them precisely to refine the scope’s pointing accuracy.
    However, the ECLIPS camera is more than just an alignment tool. It also takes full color 8° panoramas through its own wide angle lens of whatever you observe during the evening while you observe with an eyepiece through the main scope optics. It can save these images to a user-supplied SD card with no computer needed at the scope for later processing indoors on your computer. An SD card slot allows easy software upgrades and storing of your ECLIPS astrophotos on your SD card. If you prefer, it can also display the images in real time on an optional monitor or TV set via a video output jack on the LS for all to see while you observe. The camera does not shoot high power images through the telescope optics, but rather uses its own low power lens to take complementary wide angle panoramas of what you are visually observing at higher powers. This helps to put the close-up objects in context against the larger celestial background.

This Meade LS Telescope’s Mount . . .

  • Fork mount/drive system: Die-cast aluminum drive base. The light-weight, but rigid, die-cast aluminum single fork arm of the Meade LS damps vibrations quickly. There is a carrying handle at the top of the fork arm. The fork arm is long, to allow most cameras to clear the drive base when the scope is pointed at the zenith. The mount includes servo-controlled 12V DC slewing and tracking motors driving 4.875” precision worm gears in both altitude and azimuth. The motors are powered by eight user-supplied C-cell batteries that fit into the drive base. Because of all the electronic features built into the LS, the usable life of the batteries is only 3 to 5 hours, depending on the ambient temperature.
    An optional #RCXAC wall power adapter is available to power the LS from 110-120 volt 60 Hz AC household current in your back yard to conserve battery life. An optional #607 cigarette lighter cord is available to power the scope from your car’s cigarette lighter plug or a rechargeable battery for extended use in the field.

  • Adjustable height tripod: ETX-style self-centering steel leg field tripod. A single threaded rod with a large hand-tighten knob and spreader bar simultaneously holds the scope firmly on the tripod and locks the legs rigidly in the most stable position. The spreader bar has cutouts to hold three 1.25” eyepieces close at hand and up and out of the evening’s dews and damps.

  • LightSwitch Technology: The unique LightSwitch Technology of the Meade LS allows completely automatic hands-free/eyeball-free alignment of the telescope on the sky at the beginning of each observing session. A built-in GPS receiver and the patented LNT (Level North Technology) in the system’s Integrated Sensor Module combine with the built-in wide angle ECLIPS CCD imager under the telescope tube to allow the LS to completely align itself with the sky without any input or guidance from you. You simply flip the LightSwitch on and the telescope automatically finds its location, time, date; aims the optical tube north and levels it; then locates and centers the appropriate alignment stars for a perfect celestial alignment every time. You don’t have to look through a finderscope or eyepiece to automatically align the scope on the heavens for an evening’s observing enjoyment.

  • AutoStar III computer: The AutoStar III computer can show you the planets and thousands of deep space objects the very first night you use your scope – even if you've never used a telescope before! At the push of a button, the LS ACF will move at a fast 6.5° per second to any of the 100,000 objects in its database. You can choose from Messier, Caldwell, IC, and NGC deep space objects, binary and multiple star systems, the Moon, planets, asteroids, and comets. You can also automatically move to any object that’s not in the database simply by entering its right ascension and declination coordinates. The AutoStar III computer includes hundreds of special event menus, guided tours, a glossary, utility functions, and telescope status options. A hand control holder is built into the scope drive base for hands-free computer controller operation. The scope electronics and AutoStar III hand control provide full USB 2.0 support for accessories like additional DSI CCD cameras.

  • Astronomer Inside Software: It's a marvelous experience to look through a telescope at a distant object – but nothing can match the experience of knowing things like how many years its light has taken to reach your eye, how fast it’s moving, how big it is, etc. Thanks to the built-in Astronomer Inside multimedia software, the Meade 6” LS enhances the observing experience as no other telescope on today's market can. Right at the telescope, you have a complete audio/visual library at your fingertips . . . just waiting to give you a full tour of the night sky. Thanks to a built-in speaker and video-out jack, the whole family can share in the fun! An optional LCD monitor is available to let you see the more than 75 on-board animated video files in the “Astronomer Inside" software in you LS6, while the scope’s on-board speaker plays the accompanying audio. It will also display the “Astronomer Inside" still photos and menus and will display a current sky chart when not playing back videos.
    The Astronomer Inside multimedia software has over four hours of professionally produced audio content with descriptions of hundreds of objects such as the planets, Moon, stars, constellations, star clusters, nebulas, galaxies, and more. Astronomer Inside will let you learn the secrets and details of the objects you observe while you are viewing them in a fun and interesting way. It has custom guided tours of the best objects that are visible from your location, at any time and date during the course of the year. The built-in speaker in the scope’s drive base can announce audio instructions and object descriptions for all to hear. If you’d prefer to listen in private (at a star party, for example, or in your backyard when people are asleep nearby), there is also an audio out jack that will let you listen privately through optional headphones or earbuds.
    The video output jack for the optional monitor can show you more than 30 minutes of video presentations (movies and animations of celestial phenomena) and still images of many celestial objects, plus give you an instant display of images from the ECLIPS CCD imager and easy on-screen menu navigation. The multimedia presentations feature the voices of Sandy Woods of the “Star Date” astronomy radio program and George Woods, Hollywood actor.

    The simple tripod/altazimuth mount configuration of the LS ACF with UHTC optics makes setup fast and easy. The automatic alignment of the LightSwitch Technology system will have you observing in only a matter of minutes. The wide array of objects in the LS ACF database (100,000 of them!), and the pointing accuracy of the AutoStar III computer, will accurately speed you from object to object with no frustrating hunting or star hopping. With the LS ACF, you’ll spend more of your time looking at objects and less time looking for them.

    If you’re one of those busy people whose schedule doesn’t leave you much time to enjoy astronomy, an easy-to-use fully-computerized Meade LS ACF with UHTC optics will make the most of your limited observing opportunities. The 6” LS ACF is a scope that one person can easily move outside to observe by himself or herself.

    This 6” scope has enough performance with its premium coma-free design and UHTC optics to keep you busy observing and photographing for the rest of your life. And the 6” LS ACF has all the advanced features you’ll ever need to keep you happy out in the field or in your backyard. The LS is big enough to keep you observing for many years to come, portable enough to make it easy for spur of the moment observing, with superb optics and enough useful features to keep the most ardent gadget lover in seventh heaven ‘til the cows come home . . . all at a price that won’t break the bank.

    The 6” Meade LS ACF with LightSwitch Technology and Advanced Coma-Free UHTC optics may indeed be the perfect scope for you.

Supplied Eyepiece:
The eyepiece that is supplied with this telescope.
Highest Useful Magnification:
This is the highest visual power a telescope can achieve before the image becomes too dim for useful observing (generally at about 50x to 60x per inch of telescope aperture). However, this power is very often unreachable due to turbulence in our atmosphere that makes the image too blurry and unstable to see any detail.

On nights of less-than-perfect seeing, medium to low power planetary, binary star, and globular cluster observing (at 25x to 30x per inch of aperture or less) is usually more enjoyable than fruitlessly attempting to push a telescope's magnification to its theoretical limits. Very high powers are generally best reserved for planetary observations and binary star splitting.

Small aperture telescopes can usually use more power per inch of aperture on any given night than larger telescopes, as they look through a smaller column of air and see less of the turbulence in our atmosphere. While some observers use up to 100x per inch of refractor aperture on Mars and Jupiter, the actual number of minutes they spend observing at such powers is small in relation to the number of hours they spend waiting for the atmosphere to stabilize enough for them to use such very high powers.
Visual Limiting Magnitude:
This is the magnitude (or brightness) of the faintest star that can be seen with a telescope. The larger the number, the fainter the star that can be seen. An approximate formula for determining the visual limiting magnitude of a telescope is 7.5 + 5 log aperture (in cm).

This is the formula that we use with all of the telescopes we carry, so that our published specs will be consistent from aperture to aperture, from manufacturer to manufacturer. Some telescope makers may use other unspecified methods to determine the limiting magnitude, so their published figures may differ from ours.

Keep in mind that this formula does not take into account light loss within the scope, seeing conditions, the observer’s age (visual performance decreases as we get older), the telescope’s age (the reflectivity of telescope mirrors decreases as they get older), etc. The limiting magnitudes specified by manufacturers for their telescopes assume very dark skies, trained observers, and excellent atmospheric transparency – and are therefore rarely obtainable under average observing conditions. The photographic limiting magnitude is always greater than the visual (typically by two magnitudes).

Focal Length:
This is the length of the effective optical path of a telescopeor eyepiece (the distance from the main mirror or lens where the lightis gathered to the point where the prime focus image is formed). Focallength is typically expressed in millimeters.

The longer the focallength, the higher the magnification and the narrower the field of viewwith any given eyepiece. The shorter the focal length, the lower themagnification and the wider the field of view with the same eyepiece.

Focal Ratio:
This is the ‘speed’ of a telescope’s optics, found by dividing the focal length by the aperture. The smaller the f/number, the lower the magnification, the wider the field, and the brighter the image with any given eyepiece or camera.

Fast f/4 to f/5 focal ratios are generally best for lower power wide field observing and deep space photography. Slow f/11 to f/15 focal ratios are usually better suited to higher power lunar, planetary, and binary star observing and high power photography. Medium f/6 to f/10 focal ratios work well with either.

An f/5 system can photograph a nebula or other faint extended deep space object in one-fourth the time of an f/10 system, but the image will be only one-half as large. Point sources, such as stars, are recorded based on the aperture, however, rather than the focal ratio – so that the larger the aperture, the fainter the star you can see or photograph, no matter what the focal ratio.

This is the ability of a telescope to separate closely-spaced binary stars into two distinct objects, measured in seconds of arc. One arc second equals 1/3600th of a degree and is about the width of a 25-cent coin at a distance of three miles! In essence, resolution is a measure of how much detail a telescope can reveal. The resolution values on our website are derived using the Dawes’ limit formula.

Dawes’ limit only applies to point sources of light (stars). Smaller separations can be resolved in extended objects, such as the planets. For example, Cassini’s Division in the rings of Saturn (0.5 arc seconds across), was discovered using a 2.5” telescope – which has a Dawes’ limit of 1.8 arc seconds!

The ability of a telescope to resolve to Dawes’ limit is usually much more affected by seeing conditions, by the difference in brightness between the binary star components, and by the observer’s visual acuity, than it is by the optical quality of the telescope.

0.76 arc seconds
This is the diameter of the light-gathering main mirror or objective lens of a telescope. In general, the larger the aperture, the better the resolution and the fainter the objects you can see.

Telescope Type:
The optical design of a telescope.  Telescope type is classified by three primary optical designs (refractor, reflector, or catadioptric), by sub-designs of these types, or by the task they perform.
Advanced Coma-Free
Based on Astronomy magazine’s telescope "report cards", scopes of this size and type generally perform as follows . . .
Terrestrial Observation:
Observing terrestrial objects (nature studies, birding, etc.) is usually possible only with refractor and catadioptric telescopes, and convenient only when the scope is on an altazimuth mount or photo tripod. Most reflectors cannot be used for terrestrial observing. Scopes with apertures under 5" to 6" are generally most useful for terrestrial observing due to atmospheric conditions (heat waves and mirage, dust, haze, etc.) that degrade the image quality in larger scopes. 
Lunar Observation:
Visual observation of the Moon is possible with any telescope. Larger aperture scopes will provide more detail than smaller scopes, thereby getting a higher score in this category, but may require an eyepiece filter to cut down the greater glare from the Moon's sunlit surface so small details can be seen more easily. Lunar observing is more rewarding when the Moon is waxing or waning as the changing sun angle casts constantly varying shadows to reveal craters and surface features by the hundreds.  
Planetary Observation:
Binary and Star Cluster Observation:
Very Good
Galaxy and Nebula Observation:
Terrestrial Photography:
Photographing terrestrial objects (wildlife, scenery, etc.) is usually possible only with refractor and catadioptric telescopes, and convenient only when the scope is on an altazimuth mount or photo tripod. Most reflectors cannot be used for terrestrial photography. Scopes with focal ratios of f/10 and faster and apertures under 5" to 6" are generally the most useful for terrestrial photography due to atmospheric conditions (heat waves and mirage, dust, haze, etc.) that degrade the image quality in larger scopes.
Lunar Photography:
Photography of the Moon is possible with virtually any telescope, using a 35mm camera, DSLR, or CCD-based webcam (planetary imager). While an equatorial mount with a motor drive is not strictly essential, as the exposure times will be very short, such a mount would be helpful to improve image sharpness, particularly with webcam-type cameras that take a series of exposures over time and stack them together. Reflectors may require a Barlow lens to let the camera reach focus.

1. ed on 5/15/2013, said: AstronomicsAstronomicsAstronomicsAstronomicsAstronomics
Bouhgt my first scope in Feb. of 2013. Was really excited, wanted to get into astrophotography. Well, I set the scope up flipped the switch and low and behold it went through it talk, then found the GPS satilites, found N. aleigned with two stars. WOW!! How great is this. I figured I would start out easy so I choose the moon. Hmmmm. I thought this was to keep the object in the EP. The sscope was not tracking. Right out of the box it was no good. I contacted the dealer I bought it from and they sent a new scope (that they tested) W/ free shipping for the return of the first scope. This new scope I used for a month getting used to the photog aspect, then deciced to try the ccd camera that came with the scope... SD card would only go in half way. So i contacted Meade told CS that I had to bring in the scope for the SD card slot. Living in the area I thought I could just drop it off. NOOOOooo, it has to be shipped in. Not having the box to ship it in, I guess I will have to pay for it. Now, when it starts up and tries to find N. it goes to the S. So, now everything is 180 degrees off. Sorry, but this is the last Meade telescope I will buy. My next scope will be a Celestron.
