diffraction-limited Schmidt-Newtonians and
high-resolution achromatic refractors, mounted on the
all-new Autostar-controlled, LXD55 German-type
Meade LXD55-Series telescopes provide a new level of
sophistication and precision at a moderate price. All
five models of the series, including three
Schmidt-Newtonians and two achromatic refractors,
include the exclusive Meade LXD55 equatorial mount with
Autostar control system.
Meade Schmidt-Newtonian Optical System. The
highly aspheric correcting plate fully corrects
the spherical aberration induced in the image by
the primary mirror.
Schmidt-Newtonian optical systems:
Manufactured entirely at the Meade Irvine facility,
LXD55-Series diffraction-limited Schmidt-Newtonian
optics yield pinpoint stellar images over extremely wide
fields, with one-half the coma of paraboloids of the
same focal ratios. Combined with fast f/4 (8",
10") or f/5 (6") optics, the
standard-equipment Super Plössl 26mm eyepiece yields an
actual field in excess of 1.3°, for brilliant,
rich-field imaging of nebulae, galaxies, and star
clusters. High-power lunar and planetary images reveal
subtle detail often lost in telescopes of lesser optical
resolution. The optics are mounted in machined aluminum
cells fitted to white-enameled metal tubes; each tube
accepts the giant Meade rack-and-pinion focuser with
eyepiece holders for both 1.25" and 2"
LXD55-Series telescopes include an
illuminated polar alignment finder as standard
LXD55 Equatorial Mount: Designed by Meade
engineers and manufactured of machined aluminum for
high-performance photo-visual observing, the new Meade
LXD55 German-type equatorial mounting moves effortlessly
across the skies in either tracking or automatic GO TO
modes. Manual fine-adjustment controls in azimuth
(horizontal) and elevation (latitude angle) facilitate
alignment of the mounting to the celestial pole; the
standard-equipment polar alignment viewfinder, with
illuminated reticle for easy visibility against the
night sky, provides visual confirmation of precise
All LXD55-Series telescopes include a quick-release
cradle ring assembly, so that each optical
tube-with-cradle-rings-attached may be easily removed as
a unit from the mounting for transport in the field.

Battery Pack (12v DC): Included with each
LXD55-Series telescope, the battery pack rests on the
telescope's accessory shelf and plugs into the control
panel. The battery pack accepts eight (user-supplied)
D-cell batteries, which power the telescope for more
than 40 hours.
Astrophotography and CCD imaging: Armed with
their fast photographic speeds, Meade LXD55-Series
Schmidt-Newtonians are ideally suited for deep-space
astrophotography and CCD imaging at the telescope's
prime focus. Spectacular, wide-field images of extended
nebulae (e.g., the Lagoon Nebula, M8; the Orion Nebula,
M42; or the Trifid Nebula, M20) may be obtained in
minimal exposure times.
Meade LXD55-Series Schmidt-Newtonians open up
the skies to images and capabilities previously
unavailable in telescopes of their apertures and price
levels. Consider what a Meade LXD55 telescope can do for
your observing and imaging programs:
Model SN-6: 6" f/5 Schmidt-Newtonian —
Observe hundreds of galaxies, nebulae, and star clusters
of all types your very first night out, and hundreds
more the next night out, simply by pressing the Autostar
GO TO pushbutton. Watch as the telescope moves
effortlessly and automatically from major planet to
asteroid to galaxy to nebula at 4.5°/second, placing
every object in the center of the telescopic field.
Study fine fault lines on the Moon, structural detail in
Jupiter's cloud belts and Red Spot, the Cassini division
in Saturn's rings, and much more. While observing large
galactic or nebular objects such as the Andromeda Galaxy
(M31), note the tightly-focused stellar images across
the entire field of view, absent much of the coma
normally seen with fast paraboloidal mirrors. The Meade
6" Schmidt-Newtonian is fully capable of capturing
an amazing array of deep-space images in the eyepiece.
Transmission Coatings may be specified
at the time of purchase of any Meade
LXD55-Series Schmidt-Newtonian and result in a
dramatic 20% increase in image brightness and
resolution on the Moon and planets, and in
Model SN-8: 8" f/4 Schmidt-Newtonian —
With 78% more light-gathering power than the SN-6, the
8" Model SN-8 roughly triples the number of
observable objects in deep-space and resolves extremely
fine planetary detail as well: Jupiter's cloud belts are
seen as a web of intricate discontinuities; transits and
shadow transits of Jupiter's main satellites are
observable; six of Saturn's satellites may be seen in
revolution about the planet. Deep-space phenomena may be
observed in dramatically-heightened detail with the
larger 8" aperture, as Autostar moves the telescope
automatically from one spectacular object to the next.
Observe all 110 objects in the Messier Catalog, as well
as thousands of objects in the New General Catalog (NGC)
and Index Catalog (IC), locating galaxies, nebulae, and
star clusters to magnitude 14. CCD images at the
telescope's prime f/4 focus show a new level of
resolution and detail after only a few minutes'
Model SN-8 — 8" f/4 Schmidt-Newtonian
Telescope. The telescope is supplied as standard
equipment with all of the features shown,
including optical tube assembly, equatorial
mounting, Autostar control system, Super Plössl
26mm eyepiece, and 6x30mm viewfinder.
That is the only word I can utter that adequately
describes my view of the Pleiades (M45) in Taurus. To
see the entire cluster of hundreds of stars in that huge
field of view offered by the 10" LXD55
Schmidt-Newtonian was truly amazing. Faint nebulosity
permeated the cluster like no other image I've seen and
I was delighted to see razor sharp star images all the
way out to the edge of the field. The Autostar
flawlessly led me from one beautiful object to the next.
Adding a Barlow offered high power views of Saturn and
Jupiter that were nothing short of remarkable. The
telescope's fast f/4 focal ratio has already enabled me
to take some of my first astrophotos of the Orion Nebula
(M42) with great results. I was so excited to see the
results of my first night's astrophotography with film,
I am now looking forward to taking the telescope's wide
field of view and fast photographic speed into the realm
of CCD imaging...The performance of the telescope
surpasses that of instruments I have used costing many
hundreds of dollars more."

telescopes. Each telescope is shipped
complete with all equipment shown.
SN-10: 10" f/4 Schmidt-Newtonian — A quantum
leap in image brightness and resolution, the 10"
Model SN-10 provides for a lifetime of serious study in
deep-space or within the Solar System. Use Autostar to
take an automatic tour, of, say, the 200 brightest
diffuse nebulae, spiral galaxies, and globular star
clusters. Or, with Autostar's pushbutton electronic
slow-motion controls, scan the surface of the Moon at
high magnification. LetAutostar locate and center in the
field the outer planets Uranus and Neptune, now visible
as finite-sized orbs, or Pluto, at the telescope's very
limit of observability. Use the Meade
#140 2x Barlow Lens to double the telescope's
effective focal length with no diminution whatever in
resolution, and study surface detail on Mars, Jupiter,
and Saturn at high magnifications. The SN-10 presents
wide, extremely bright star fields at lower powers,
while resolving, under favorable seeing conditions,
remarkable lunar and planetary detail at higher powers.
It is an uncommon observer who might outgrow the
capabilities of the Meade 10" LXD55.
Model AR-6 — 6" f/8 Achromatic Refracting
Telescope. The telescope is supplied as
standard equipment with all of the features
shown, including optical tube assembly,
equatorial mounting, Autostar control system,
Super Plössl 26mm eyepiece, and 8x50
Meade LXD55-Series Achromatic Refractors: With
objective lenses that resolve to the theoretical limits
for their apertures, Meade 5" and 6" LXD55
refractors present all of the diffraction-limited
optical performance obtainable from the classical
2-element achromat design. Deep-space images, in
particular, are rich in resolution and contrast, with a
minimum of chromatic aberration.
LXD55 Control Panel is conveniently located
below the upper bearing of the polar axis and
includes 4 connectors and the ON-OFF switch.
LXD55 Equatorial Mount: Both refractors
incorporate the Meade LXD55 equatorial mounting for
smooth, effortless sidereal-rate tracking in RA or for
automatic dual-axis GO TO operation at 4.5°/second with
the standard-equipment Autostar hand controller.
Precision worm gears on both axes assure low-backlash
operation at all nine Autostar speeds. A 12v DC battery
pack rests on the telescope's accessory shelf and
operates either instrument for over 40 hours from eight
(user-supplied) D-cell batteries.
Dual-Axis Electronic Control System: Locate any
of 30,223 celestial objects in the Autostar database -
automatically - at a push of the GO TO button.
Observing with a Meade 5" or 6"
refractor is an experience unlike that with other
telescopes, as the refractors' large unobstructed clear
apertures enable a level of resolution and high contrast
normally reserved for larger instruments of other types.
5" and 6" Achromatic Refractors are
shipped complete with the LXD55 equatorial
mount, Autostar dual-axis control system, and
Model AR-5: 5" f/9 Achromatic Refractor —
Explore over 30,000 of Autostar's database objects —
galaxies, nebulae, and star clusters — or any object
of known RA and Dec., as the telescope moves
automatically at 4.5°/sec. to locate and center each
object. The AR-5 yields satisfying images of the Moon
and planets: use the Autostar slow-motion pushbuttons to
rove over the surface of the Moon at high power or to
resolve surface detail on Jupiter and Saturn.
Design of Meade Achromatic Refractors. Light
travels through the front lens element of
optical crown glass, then through the rear
flint-glass element and is brought to a focus at
F. The crown and flint glass elements have
different indexes of refraction, permitting the
design to be achromatic, or color-corrected.
Model AR-6: 6" f/8 Achromatic Refractor —
The Meade 6" LXD55 refractor, with 44% more
light-collecting power than the 5" model, permits a
much wider imaging capability. Deep-space objects, from
bright galaxies like Andromeda (M31) to faint nebulae
like NGC 6559 in Sagittarius and thousands of other
galaxies, nebulae, and star clusters in between, take on
added brightness and resolution of form and structure.
Globular star clusters, such as M13 in Hercules, are
better resolved, often to the core of the cluster.
Significantly increased detail is visible on the Moon
and planets; double stars may be split to the
telescope's 0.74-arc sec. limit.
