Most people who have never looked through a quality, moderately-priced telescope have no real idea of how much
can be observed. Common perceptions are that a telescope capable of showing the rings of Saturn, for example,
costs "thousands of dollars," or that reading an automobile license plate from one mile requires a telescope out of a
spy novel. Such perceptions could not be more wrong.
The extremely wide range of celestial objects observable through amateur telescopes can be categorized into the
|1. Objects in the Solar System|
The Moon, Planets, Comets: Because of their relative proximity to Earth, the
Moon and major planets have long been primary sources of interest to amateur astronomers. Each of the major
planets from Mercury to Neptune is visible through any Meade telescope; only the outermost
and faintest planet, Pluto, requires a telescope of 10"-aperture or larger to be seen.
The Moon: Observed through even the smallest of Meade telescopes (e.g., NG-60, NGC-60), the Moon is
transformed into a stark world of impact craters, mountain ranges, pock-marks, rilles, and fault lines. Larger Meade
models (e.g., the Meade ETX series, as well as the DS-2000 series, and LXD55 series) permit the resolution of very
fine detail on the lunar surface: craterlets, surface color variations, and the structure of crater walls. With an advanced
Meade telescope (e.g., Models 8LX90 or 8LX200GPS) the Moon can become the subject of a lifetime of research
The smallest Meade telescopes, Models NG-60 AND NGC-60, show about this level of visble detail on the surface of the Moon. Meade 10" Schmidt-Cassegrain photo by C. Arsidi.
Mercury and Venus: Seen through the Meade NG-60 or NGC-60, Mercury and Venus move through a series of Moonlike
phases—crescent, half, and full—as they orbit the Sun. Larger telescope models can occasionally show dusky
markings on the surface of Venus.
Mars: Long a subject of myth and mystery, the planet Mars shows a reddish coloration in the telescope, with dark
surface markings, as well as white polar ice caps, observable in any Meade telescope. The ease of observing these
markings is strongly dependent on Mars' distance from Earth, a distance that varies considerably from year to year.
Larger telescope aperture is also greatly beneficial in observing Mars; advanced amateurs normally consider an 8"
telescope (e.g., Meade LXD55 series or LX200GPS series) as required equipment for serious study of the planet.
Jupiter: Because of its wealth of observable surface detail, Jupiter is perhaps the most studied planet among amateur
astronomers. In Meade Models NG-60 or NGC-60 the planet's primary cloud belts are readily visible, as are its four largest
moons, or satellites, in revolution about the planet and changing positions from night to night. Through larger Meade
telescopes, such as the ETX Series, DS-2000 Series, or larger, the cloud belts take on added
structure and color that are seen to change slowly but perceptibly from week to week. The high-resolution imaging
afforded by the Meade ETX permits the study of significant detail on Jupiter's surface, including the Great Red
Spot. Viewed through a Meade LXD55 Series or through any Meade 8" telescope under good atmospheric
conditions, Jupiter displays numerous cloud belts, as well as an intricate web of whirls, festoons, and discontinuities,
and the planet's four largest satellites become finite-sized orbs rather than pinpoints.
The planet Jupiter shows a wealth of ever-changing detail when observed through a Meade ETX, or larger, telescope. Meade CCD image by Dr. Donald Burns; 10" LX200 telescope equipped with a Stellar Products AO-2 adaptive optics system.
Saturn: Easily visible through any Meade telescope model, Saturn and its famous ring system are a stunning sight.
Meade NG-60 and NGC-60 also enables observation of Saturn's largest moon, Titan. The Meade ETX permits
resolution of Saturn's primary ring-division, the Cassini Division, observed as a pencil-thin line in the rings. The ETX Series and LXD55 series also display, under favorable observing conditions, dusky, yellowish cloud belts across
the planet's disc, as well as shadows cast by the rings on to the planet's surface.
Uranus, Neptune, and Pluto: Unknown to the ancients, Uranus and Neptune can be tracked and observed even
through Meade 60mm-aperture telescopes, NG-60 and NGC-60. The planetary images, as compared to starpoints,
are seen as finite-sized discs. The higher magnifications that may be employed with larger telescopes (DS-2000 series, LXD55 series) sometimes allow observation of the pale greenish-blue
atmosphere of Uranus and the yellowish color of Neptune. The automatic object-locating capabilities of Meade 10",
12", 14", and 16" LX200GPS models are of particular value in observing the outermost planet, Pluto, visible as a tiny faint
point more than 3 billion miles from Earth.
The ETX-90AT is ideal for lunar, planetary and deep-space observations.
Minor Planets (Asteroids): Located between the orbits of Mars and Jupiter are thousands of minor planets (the
largest of these is about 480 miles in diameter) called asteroids. Asteroids can be observed, and their paths plotted in
motion among the stars, through all Meade telescope models. Larger telescopes, such as Meade DS-2114ATS, DS-2130ATS, LXD55 series, permit the observation of literally hundreds of asteroids of widely varying brightness
In 1996 Comet Hyakutake was a splendid object through any Meade telescope model. Meade CCD image by Jack Newton.
Comets: Appearing generally on unpredictable schedules, comets often provide dazzling objects for observation
through the telescope. Although bright comets are relatively rare, many fainter comets are observable through even
small telescopes (e.g., Meade NG-60, NGC-60, and larger) in almost every month of the year.
Objects in the Solar System, as fascinating as they are to observe, are only the first step of the grand space tour
enabled by a Meade telescope. Outside the Sun's planetary system is the realm of deep-space—the realm of stars,
star clusters, gas clouds (nebulae), and galaxies.

|2. Objects in our Milky Way Galaxy|
Star Clusters: Positioned throughout our Milky Way galaxy are various types of star clusters, including loose stellar
associations (open star clusters) and tightly packed ball-shaped star groupings (globular star clusters). The
Pleiades, an open cluster of 6 or 7 stars easily visible to the unaided eye, becomes a glittering sight in any Meade
telescope, with hundreds of stars now visible through the eyepiece. The globular star cluster (listed in celestial catalogs
as M13) in the constellation Hercules is only a faint smudge without the telescope; through a Meade DS-2114ATS,
M13 resolves into a glowing ball of incandescence, with many outer stars in the cluster clearly resolved.
The Pleiades (M45), and open star cluster, displays several hundred stars through any telescope. Long exposure photographs reveal a blue enveloping nebulosity. Meade 10" Schmidt-Cassegrain photo by C. Kimball.
The Big Dipper in the constellation Ursa Major. Resolving the fainter star Alcor from the brighter Mizar is a good test for the unaided eye. Through any Meade telescope Mizar itself further resolves into two clearly seperated component stars.
Double and Multiple Stars: Of the 100 billion stars in our galaxy, roughly half of them are multiple stars consisting
of two or more stars linked in a common gravitational field and revolving about a common center. The famous star
Mizar, located at the bend of the handle of the Big Dipper, resolves into two stars of about equal brightness. High in
the summer sky the constellation Cygnus (the "Northern Cross") contains one of the most observed double stars, the
star Albireo, which resolves into brilliant yellow and blue components when studied through a Meade Model NG-60, NGC-60, or
larger, telescope. Hundreds of other double and multiple stars can be observed with any Meade telescope.
Variable Stars: Many stars are not fixed in their brightness levels, but periodically change in brightness, some in
days, others over a period of years. In the easily-located constellation of Perseus, the star B (beta) Persei, or Algol,
changes brightness rapidly every three days, dimming from moderately bright to moderately faint in a period of only
about four hours. Algol's fascinating variability in brightness is easily studied in any Meade model. Larger telescopes,
including Meade DS-2000 series, LXD55 series, 8LX90 and LX200GPS, permit the observation of hundreds of variable
stars throughout the sky.
Nebulae: Gas clouds, called nebulae, are scattered throughout our own galaxy, the Milky Way. These clouds
typically are illuminated by nearby stars. Nebular objects are further grouped into sub-types as tenuous, amorphous
clouds (diffuse nebulae) and highly structured clouds of gas (planetary nebulae). Use a beginning to intermediate
Meade telescope (e.g., Models NG-60, NGC-60, DS-2070AT, DS-2114ATS, DS-2130ATS) to observe such spectacular objects as the Great Nebula in
Orion, a diffuse nebula that fills the field of view at low powers. Within the Orion Nebula a
grouping of four stars, called the "Trapezium" because of its trapezoidal orientation, illuminates the nebula and can be
easily viewed with any Meade telescope. Larger telescopes such as the Meade LXD55 series, allow the observation of dozens of additional stars embedded in the nebula. Or consider the
planetary nebula known as M57 (the "Ring Nebula") in the constellation Lyra. Visible through even the smallest
Meade telescope, M57 is clearly defined in the Meade ETX, and becomes a splendid sight in larger telescopes, such
as the Model 8LX90, or LX200GPS. Long-exposure photographs of the Ring Nebula through Meade 8" models and larger
reveal a faint central star that illuminates the gaseous ring.

Galaxies: Subdivided into spiral and elliptical types, galaxies are large islands of billions of stars located throughout
the visible universe. From a practical point of view the number of galaxies in the universe is virtually uncountable.
Bright galaxies abound in the night sky: the Andromeda Galaxy, seen without a telescope only as a fuzzy spot, blooms
into a large elliptically-shaped field of apparently glowing gas (actually a grouping of more than 100 billion stars)
through any Meade telescope; with the ETX series or DS-2114ATS the galaxy's structure starts to become visible;
photographed through a Meade 8" telescope (Models LXD55 (SC-8, SN-8), 8LX90, or 8LX200GPS), the Andromeda Galaxy
is seen in wide extension, with the primary dust lanes in its spiral pattern prominently displayed.

It should be emphasized that the above listing only hints at the breadth of celestial objects within the view of any
Meade telescope. The larger the telescope's main lens or mirror, the more detailed, the more resolved, the brighter
will be all of the objects observed, from the Moon, to the planets, to deep-space galaxies. But even through the lens
of the smallest Meade telescope, the NG-60, NGC-60, the night sky is transformed into a universe never before seen with
the unaided eye. A Meade telescope of any aperture size permits the user to uncover some of the most stunning sights
in all of nature and to observe these sights as most people never thought possible.
Locating Astronomical Objects: Finding objects for observation in the telescope requires only a modest
knowledge of the sky, a knowledge that can be quickly and easily obtained from inexpensive Star Charts, or from Autostar Suite astronomical software, perhaps the
easiest means for learning the sky. Starting with the brighter constellations and objects, the novice observer finds that
within one or two observing sessions at the telescope, he or she is "star hopping" from one, known, object to another,
unknown, object with ease.
|Photography Through the Telescope; Digital CCD Imaging, LPI Imaging|
Photography of the Moon, planets, and
deep-space objects adds an exciting dimension to any observing program, and, as demonstrated throughout the Meade website, many amateurs have achieved remarkable astrophotographic results, results which a few decades ago were
possible only with large observatory telescopes. With a Meade ETX-90AT, DS-2114ATS, DS-2130ATS, or larger, telescope,
optionally available photo adapters can be used with most 35mm SLR camera bodies for terrestrial photography or
for photography of the Moon and planets. Long-exposure photography of deep-space galaxies, nebulae, and star
clusters requires that the telescope be equipped with a motor drive and drive corrector.
Digital imaging of astronomical objects with the telescope by means of the CCD (Charge-Coupled Device) microchip has rapidly advanced in recent years. Meade CCD imagers permit the telescope user to take astronomical images, often in a minute or two, for viewing on the display of a personal computer. These images can then be processed to reveal nebular structures, for example, that are invisible in most astrophotographs.
The Autostar Suite Software and Lunar Planetary Imager has ushered in a new era in astronomical imaging. The LPI (Lunar Planetary Imager) combines the power of an electronic astronomical imager/ autoguider with the simplicity of a webcam. The LPI uses a CMOS sensor to capture high definition images of the Moon and Planets. These images can then be automatically selected for sharpness, stacked and combined, to form a high definition image. The LPI can also be used to Autoguide any advanced "Autostar" operated telescope for long exposure photography.
Terrestrial Observing: All Meade telescopes can be equally well applied for
land-view applications as well as for astronomy, and in these cases the astronomical-quality optics generally
outperform most telescopes designed exclusively for terrestrial use. Recognize the faces of people from more than
one mile; study the feather structure of a bird from 50 yards; observe insects on a flower from 25 feet. Terrestrial
applications of Meade telescopes are as limitless as your imagination.
All Meade telescopes can be used for a wide range of high-resolution terrestrial observing.
