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 Tim Kristi; The Reflector of The Astronomical League, August,
2002.

"...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" cpatures 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."

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 reveal a tremendous range

"...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."

to locate targets to a precision of within a few arcminutes. The
