Large apertures combined with a dazzling array
of state-of-the-art LX200GPS-SMT features, including
145,000-object database, Zero Image-Shift Microfocuser,
GPS Alignment, and High-Precision Pointing.
The large
light-collecting apertures of Meade 12" and 14"
LX200GPS-SMT telescopes enable levels of resolution
and image brightness that satisfy the advanced requirements
of the serious amateur, as well as those of many school
or college research programs. The 12" model,
for example, gathers 44% more light than Meade 10"
Schmidt-Cassegrains; the 14" LX200GPS-SMT has
96% more light-collecting area than the 10" telescope.
Meade 12"
and 14" LX200GPS-SMT Schmidt-Cassegrains include
all of the features of the 8" and 10" models:
accurate GPS alignment; onboard 145,000-object database
accessible in seconds through the Autostar II hand
controller; Autostar Suite Software with remote telescope
control via internet, the Lunar Planetary Imager (LPI),
the creation of custom tours and much more; 4-speed
Zero Image-Shift Microfocuser; High-Precision Pointing
to within one arc-minute; and much more. And yet,
notwithstanding all of their high-performance features,
Meade 12" and 14" LX200GPS-SMT telescopes
are readily transportable for use in the field.
The telescopes'
progressive-tension primary mirror lock, in conjunction
with the Zero Image-Shift Microfocuser, cancels any
residual image-shift during focusing. In addition
the mirror lock results in even more precise long-distance
GO TO slews of the telescope, since the large mass
of the telescope's primary mirror is locked in position.
In Addition to that, the Smart Mount improves the
pointing accuracy of the LX200GPS-SMT telescope's
"Go To" system. Despite careful efforts
to calibrate and then align telescopes, they may fail
to precisely center objects. Smart Mount allows your
telescope to learn about, and then correct for any
systematic pointing errors, regardless of the cause.

"We
have been using Meade telescopes since our inception
with remarkable success. We began with your 8-inch
LX200 and now have one of your 12-inch LX200 models
permanently mounted in our observatory. This instrument
has proven to be extremely reliable and has allowed
us to successfully conduct viewing opportunities for
thousands of our Hawaii residents. It has also served
us well for our 15 to 25 sections of astronomy classes
we offer each academic year and has been an excellent
research instrument for our undergraduate astronomy
projects.
During
November, 1997, a group of astronomers from Hopkins
Observatory at Williams College in Massachusetts flew
out to use our observatory for the occultation of
the 10th-magnitude star Tycho 651672 by Neptune's
13th-magnitude satellite, Triton. The astronomers
attached their imaging system to the 12-inch Meade
LX200. The telescope acquired Neptune and resolved
Triton easily; tracking was excellent. The entire
system worked flawlessly. The 12-inch Meade LX200
successfully took 8000 images of Triton as it ran
unattended, with the Hopkins imaging system attached,
during the 17-minute occultation. We were the only
observatory in Hawaii to get images of this event.
Your company has enabled the small college to open
a world of excitement, discovery, and meaningful undergraduate
research at a cost easily within our reach."

Observing
with the 12" LX200GPS-SMT: The advantage
of large aperture immediately becomes apparent when
observing with the 12" LX200GPS-SMT. Objects
merely visible in smaller telescopes now take on new
dimensions, with fainter, more tenuous nebular detail
observable; the Orion Nebula grows to more than twice
the area visible in an 8" telescope and with
subtle color variations. Jupiter's surface is a web
of interlocking structural detail, even under moderate
seeing conditions; shadowy detail on the surface of
Jupiter's largest satellite, Ganymede, is often observable.
With a limiting photographic magnitude of 17.5 (or
over 18.0 if the telescope is equipped with the optional
Meade Ultra-High Transmission Coatings group
), the 12" LX200GPS-SMT is a valuable tool in
supernova patrols, in the plotting of faint asteroids,
and in many other areas of significant astronomical
research.

"We began our quest to CCD image the Arp Peculiar
Galaxies on 11/02/01, using the 12" Meade LX200
located in the Astro Imaging Center next door to Powell
Observatory in Louisburg, Kansas...Halton Arp used
the 200" Hale telescope on Mt. Palomar to obtain
[his original] photographic plates [of 338 Arp galaxies].
We were thrilled that with a 12" scope we could
easily identify the Arp galaxies, and in some instances
pick up significant detail and structure...we got
some great images. We now [have] bagged almost 150
Arps. We accomplished in just a few nights what took
Halton Arp months and a multi-million dollar telescope
to accomplish." — from "Scoping
Out Arp Peculiar Galaxies with a 12" Meade LX200
and SBIG ST-9E CCD Camera" by Bill Boyle and

"...Wouldn't
it be great if we could image the finest possible
detail on Jupiter or the hairline divisions in Saturn's
rings even on nights of moderate atmospheric turbulence?
Well, we can. Department-store technology is all it
takes to assemble an imaging system that removes the
twinkle from stars and fuzziness from planets. All
this method requires is a telescope with excellent
optics, some off-the-shelf video and computer equipment,
and a bit of patience.
My
results have consistently exceeded expectations. With
a Meade 12-inch Schmidt-Cassegrain telescope in moderate
turbulence I regularly resolve features at the Dawes
limit of 0.4 arcsecond. I can even do this in a solar-heated
and normally more turbulent daytime sky. [Images of
the Space Shuttle in orbit] clearly show the wings,
cargo-bay doors, and even the cockpit windows. I have
also resolved Mir's solar panels and modules, even
when the space station was hundreds of kilometers
away. Images of bright stars reveal diffraction rings
both day and night, and planetary details are extraordinary...."

"Just
a note to let you know of my very pleasant surprise
I got when I checked out one of your 12" LX200GPS-SMT
telescopes for a friend recently. I have been looking
through telescopes for 44 years now and have looked
through thousands of SCT's. This 12" LX200GPS
has optical quality that is very likely the best I
have ever seen!
The
star image at 500x showed no astigmatism and the least
spherical abberation that I ever recall seeing with
an SCT. Not only was the central darkening the same
size on both sides of focus but inside of that was
a similar bull's eye pattern. I have seen this pattern
on one side of focus from time to time on unusually
good SCT's but NEVER on both sides. This scope has
the UHTC coatings and right from the start I noticed
the contrast was unusually high. Nebula and star clusters
were not only crisp, but sharply defined as they literally
popped out from the velvety black background.
Mars
was a wonderful sight to see with details on the polar
cap and surface markings only limited by the seeing
conditions. All in all I was stunned with the quality
of this telescope and it takes a lot to stun me these
days. You should be proud of yourselves for getting
so close to perfection on such a difficult telescope
to produce, and at a price that is ridiculously low
for this type of quality. I made my friend promise
to offer this telescope to me first if he ever decides
to sell it, but I doubt he ever will. Thanks, and
keep up the great work. "

Observing with the 14" LX200GPS-SMT: With
a resolving power of 0.32 arcseconds, the Meade 14"
Schmidt-Cassegrain is an advanced instrument capable
of serious research. When equipped with the optional
Ultra-High Transmission Coatings group, the
telescope presents an image brightness fully equivalent
to that of a 15" telescope with standard coatings.
Observing with the Meade 14" Schmidt-Cassegrain
is an extraordinarily rewarding experience. The advantages
of the telescope's large diffraction-limited aperture
are immediately apparent, particularly to the advanced
observer with an

"Tonight
was by far the best view of Mars I've ever had. It
was close and I was able to work with magnifications
up to 395X, which made it really bid in the eyepiece.
...M13
is a great way to start the evening off with a bang.
This globular always pleases, and in the 14"
it's wondrous.
...I'm
definitely addicted to the 14". It exceeds the
12" GPS very significantly in all areas, including
difficulty in transport. Forget about the 16"
GPS. This is Meade's Ultimate Scope."
...Conditions
tonight were good to average for this location. And
the 14" enhances all views. I haven't used the
12" since the bigger scope arrived. Both are
UHTC, and the 12" is a beautiful scope. But the
14" captures enough extra photons that I can
hope to see difficult objects like the central star
in M57 even when beset with light pollution and haze
and poor seeing. Also, being an engineer I can't help
but favor the technically superior scope. "

eye trained to discern extremely fine detail on the
full range of celestial phenomena - lunar, planetary,
and deep-space. Studies of the more obscure Messier
and NGC objects such as the planetary nebula NGC 3242
in Hydra, the spiral galaxy M100 in Coma Berenices,
and the open cluster NGC 6231 in Scorpius, show a
heightened level of resolution invisible in smaller
telescopes. Difficult objects like the Crab Nebula
(M1) in Taurus, the Spiral Galaxy (M33) in Triangulum,
and the Owl Nebula (M97) in Ursa Major begin to show
their essential structures under high-power visual
observation; these same objects present magnificently
detailed images as the subjects of long-exposure CCD
or film.

"The
Meade 14" LX200GPS-SMT combines all the attributes
in a telescope that we seek in our public outreach
programs: high-performance, large-aperture optics;
extremely precise GO TO automatic pointing; and a
rigid fork mounting fully up to the tasks of long-exposure
CCD imaging and astrophotography. Please pass along
our congratulations to your engineering and optics
departments for a job very well done."

cameras. Under favorable atmospheric conditions binary
stars may be resolved to the telescope's theoretical
limit, and, just as importantly, the telescope's high-contrast
internal mirror baffling allows for the resolution
of a large number of binaries where the brightness
of the primary far exceeds that of the secondary.
Note in the 14" telescope the subtle shadings
of Saturn's inner ring structure, as well as the varying
contrast levels of the cloud belts and the small polar
cap on the planet's surface. Jupiter's cloud belts

"...After
the weather cleared, I had the chance to thoroughly
test out the 14" LX200GPS-SMT Schmidt-Cassegrain,
doing dozens of GO TO's over a period of several hours...First,
my overall conclusion: this is one awesome telescope!
By now Meade optics are assumed to be diffraction-limited,
and the 14" is no exception. Intrafocal and extrafocal
stellar images are virtually identical; subtle variations
in contrast (such as on the surface of Jupiter's largest
satellite, Ganymede) are readily identifiable; and
thanks to the enhanced [UHTC] coatings, images are
significantly brighter than in other 14" telescopes
I have used...The telescope easily passed all of the
usual double-star tests for superior optics.
In deep-space
the telescope provided a simply stunning experience.
The Whirlpool Galaxy (M51) stood out in clear detail
with its spiral arms and satellite galaxy (NGC 5195)
well-defined. The ninth-magnitude galaxy M94 was an
easy object; the bright, dense nucleus of the galaxy
contrasted nicely with the fainter, wispy outer regions.
The Hercules globular cluster (M13) was magnificent,
as expected, but what surprised me was the quantity
of stars that are now resolvable in the telescope.
In a true test of the telescope's light grasp, I was
able to see, using averted vision, the magnitude-15.4
central star of the Ring Nebula (M57) in Lyra.
I topped
off my evening session at the telescope by observing
Jupiter and Saturn at high powers. At 367X Jupiter
exploded into a mass of detail — wave-like belt
structures, colors, and knots of just superb resolution...when
the seeing improved later in the evening, I added
a Barlow to up the magnification to 734X. Still the
image maintained absolute clarity and definition.
During moments of super-seeing I glimpsed Saturn's
Encke Division (less than 0.10 arcseconds wide). The
14" is definitely a superb planetary instrument.
In the short time that I have used it I could write
a book on the visual capabilities of the telescope.
I truly believe that in the 14" LX200GPS-SMT
you have created a world-class research telescope."

of color shadings,
as well as whirls, festoons, and discontinuities almost
too numerous to count. Observation of transits of
Jupiter's four primary satellites across the disc
of the planet, and of the shadows of these satellites
on the planet, is routine. Even at distant oppositions
Mars displays significant surface detail; at close
oppositions the planet becomes a mass of intricately-connected
dark plains and ochre-colored deserts.
The Meade
14" LX200GPS-SMT includes an all-new fork mounting
of uncommon structural rigidity. For added strength
and stability the fork's polar cross-bar assembly
is cast in one continuous piece from one fork arm
to the other; the motor drive base includes a thickened
cast floor to minimize flexure of the telescope when
mounted on the optional Superwedge at low latitudes.
The mounting combines with the Autostar control system
for long-distance slews across the skies |

"I
have nothing but praise for my Meade 12" LX200.
It has provided me with very fine images of the planets,
my special area of study, and operated without fault
for five years. Planetary observing is probably the
most demanding area of amateur study for any instrument,
as the telescope must have optics of exceptionally
high quality. The 12" LX200 provides detailed
visual and CCD images of Mars even when the planet
is far from opposition, a wealth of fine detail on
Jupiter and Saturn, and memorable observations of
binary stars and globular clusters. I would recommend
(and have recommended!) without hesitation the 12"
LX200 to advanced amateurs seeking a truly high-performance
telescope that can quite literally do it all."
