Our Rocket Telescope 375X is a powerful
reflector telescope with a maximum magnification of 375x
(images appear up to a whopping three hundred and seventy
five times bigger!), making it among the most powerful
childrens' telescopes available, and perfect for discovering
the solar system from the garden or bedroom window. Our
Rocket 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 CHILDS CELESTIAL TELESCOPE
Our Rocket 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 - 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 325x magnification opens up a whole new world!
The Barlow lens supplied increases the magnification of
the telescope. A 125X magnification can be increased to
375X 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 Rocket 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).
