The EXPLORER-150P (EQ3-2) transforms the popular Newtonian
telescope into a powerful astronomical tool. It offers sharp
and bright images, enabling you to view objects during the
day, and dazzling sky-objects during the night. It also
serves as an attractive home decoration. Our EXPLORER-150P
(EQ3-2) Reflector Telescope is manufactured by Sky-Watcher,
one of the most respected telescope manufacturers - products
you can trust, representing great value for money. The Sky-Watcher
EXPLORER range are standard Newtonian reflectors of excellent
quality and versatility, ranging in aperture from a respectable
130mm to an incredible light-gulping 200mm aperture, catering
for astronomers of all levels. Whether your interest is
Deep-Sky, the Moon and Planets, or a combination of both,
the EXPLORER range offers excellent all round Diffraction-Limited
performance. Tube material : Aluminium.

EXPLORER-150P (EQ3-2) Telescope
"Good for advanced observing"....."Saturn
was a stunning sight"
BBC Sky At Night Magazine |
| ”Optical quality good, and this
is a good telescope for the amateur. On the EQ3-2
mounting the total comes to £289, and this is excellent
value for the serious beginner.” Sir Patrick

Our EXPLORER-150P (EQ3-2) Telescope
is a 'reflector' telescope (sometimes called a 'reflecting'
telescope). Reflector telescopes use a concave mirror
to collect the light coming from the object being oberved
(eg the moon), and reflect this up to the eyepiece.
The most important thing to look for in a telescope is
the quality of the lenses and mirrors. Generally speaking,
for a reflector telescope, the larger the diameter of
the main mirror, the more light can be collected, and
hence the greater the quality of the magnified image.
Usually, the more you pay, the higher the quality of the
magnified image. This is not always the case though among
the telescopes we regularly review.
The EXPLORER-150P (EQ3-2) telescope benefits from Sky
Watcher's Aspherical Technology, usually only found in
larger, more expensive telescopes. The primary mirror
is altered during polishing to bring the light rays onto
a common focal plane, resulting in sharp images full of
detail. Using this technology, the EXPLORER-150P (EQ3-2)
76 telescope can therefore boast about having what is
known as a parabolic mirror, rather than inferior spherical
mirrors used on many other telescopes. The result is that
the EXPLORER-150P (EQ3-2) produces remarkably bright and
clear images. Its intuitive manoeuvrability makes it a
perfect user-friendly telescope. Setting up the telescope
is easy.
What we also particularly like about the EXPLORER-150P
(EQ3-2) telescope is that it achieves a very good trade-off
between quality and price. The magnification of 150x may
seem low in comparison to quoted magnifications of other
telescopes, however this enables the EXPLORER-150P (EQ3-2)
to offer a wide range of view and this is all done with
optics that are superior in quality to other telescopes
in this price bracket. The result is that the EXPLORER-150P
(EQ3-2) provides particularly clear and bright images
that reveal more in the night sky than other telescopes
quoting higher magnifications, which commonly suffer from
poor-quality, low-detailed and dull images with such a
narrow field of view that proper observation is impossible.
EXPLORER-150P (EQ3-2) enables amateur astronomists to
discover a wealth of hidden secrets in the night sky,
without costing the earth! And, we have to admit, the
remarkable quality of the images makes this telescope
stand out from other telescopes in this price range.

In 1609, Galileo Galilei first looked through his telescope, and changed
science forever. His discoveries provided solid evidence that disproved
the prevailing belief that the Earth was the centre of the Universe. Throughout
history, scientists such as Johannes Kepler and Sir Isaac Newton further
revolutionised the design of the telescope. To celebrate the International
Year of Astronomy 2009, we are proud to present two special commemorative
editions as a tribute to this rich ‘heritage’.

| Choosing a Telescope:
There are two main categories of telescope: Refractors and Reflectors. Refractors,
use two or more lenses to collect and focus the light from an object to
the eye of the observer, and can trace their design back to the telescopes
of Galileo’s era. Reflectors (like the one shown on this page), developed
by Isaac Newton in the 17th century, use mirrors to focus the light. As
magnifications increase, impurities in the glass of lenses can cause distortion
(commonly a “rainbow-like” halo around objects) requiring expensive and
difficult treatments and coatings to correct. Reflectors telescopes avoid
this problem, and are generally cheaper to manufacture for a given sized
aperture (the main lens or mirror used to catch the incoming light). As
a result, most high-performance optical telescopes, including the Hubble
Space Telescope, are reflector designs. |
SKY-WATCHER DELUXE MIRROR COATINGS: Most reflectors today usually
have a coat of aluminium as the mirror surface and then an overcoat of silicon
monoxide or silicon dioxide to protect it. Silicon dioxide produces a much
more durable coat than silicon monoxide but requires specialized equipment
to apply it and is therefore more expensive. Protection is needed, because
in most reflectors, the mirror is open to the elements and deterioration
of the reflective layer reduces the resolution of the telescope. ALL Sky-Watcher
reflectors are Multi-Coated with Silicon Dioxide as standard for Optimum
Durability and Long Term Performance.

Please note: Viewing the sun can cause permanent eye damage. Do not
view the sun with the Telescope, Finderscope or even with the naked eye.
To observe the sun, it is best to project the view onto a piece of white
card (see intsruction booklet).
