Our Magnum Power Telescope 675X is
a powerful reflector telescope with a maximum magnification
of 675x (yes, images appear up to an amazing six hundred
and seventy five times bigger!), making it among the
most powerful telescopes available for home use, and perfect
for discovering the solar system from your garden or bedroom
window. Our Magnum Power Reflector Telescope is brought
to you by the famous Science Museum in London - products
you can trust, representing great value for money.

THE
SCIENCE MUSEUM'S MOST POWERFUL TELESCOPE
Our Magnum Power 675x 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. Reflector telescopes are ideal
for looking at the stars and planets, as they are generally
more powerful than similarly-priced refractor telescopes.
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. What we particularly
like about this Science Museum telescope is that the telescope
achieves a very good trade-off between quality and price.
This telescope is powerful enough to enable amateur astronomists
- especially children and curious adults - to discover
a wealth of hidden secrets in the night sky, without costing
the earth!
This telescope comes with a number of different eyepieces,
so that various magnifications can be used - you will
not always want to use the most powerful magnification,
as there is a trade-off between field of view, image brightness,
and magnification. For very bright objects, such as the
moon, full 675x magnification opens up a whole new world!
The Barlow lens supplied increases the magnification of
the telescope. A 225X magnification can be increased to
675X with a 3X Barlow lens.The highest magnification power
of the Barlow lens should only be used for large and bright
objects such as the moon and the brightest planets, as
well as for nights with optimal observation conditions.
Our Magnum Power telescope is fitted with an Altitude(Alt)-Azimuth
mount. "Altitude" refers to the vertical movement of the
telescope, while "Azimuth" refers to the horizontal movement.
The Altitude-Azimuth mount, in conjunction with the fine-adjustable
altitude control, and the Azimuth Lock enables you to
observe the entire night sky, or any celestial body, without
having to move the tripod.

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.
Science Museum: The Science Museum in London is one
of the world's pre-eminent science museums, and voted one
of the World’s Top 5 Tech Mecca’s by The Observer. It is
also the UK’s No. 1 visited Museum. The Science Museum houses
outstanding collections relating to science, technology
and medicine, and is one of the most prestigious and respected
organisations dedicated to the promotion of public science
and technology. The origins of the Science Museum lie in
the nineteenth-century movement to improve scientific and
technical education. Prince Albert was a leading figure
in this movement, and he was primarily responsible for the
Great Exhibition of 1851 to promote the achievements of
science and technology. The profits of the hugely successful
Exhibition were used to purchase land in South Kensington
to establish institutions devoted to the promotion and improvement
of industrial technology. At the same time, the Government
set up a Science & Art Department which established the
South Kensington Museum in 1857, from which the Science
Museum and Victoria & Albert Museum have developed.
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).
