This simple children’s rhyme tells an amazing story
about humankind’s fascination with the gently sparkling
objects in the sky that reveal themselves at night when
the sky is clear.
This poem encapsulates many things that very early
humans knew or believed about the night sky – that it
was scattered with bright dots of light that couldn’t be
seen when the sun was in the sky, and that some of these
lights were brighter than others. It also reveals the
mystical and supernatural qualities that people placed
on these glowing specks – that these twinkling lights
could somehow have an influence on our lives.
In ancient times the sky was seen in religious terms,
with the sun and moon being gods that crossed the sky
along with the bright, moving spots (planets) that
didn’t twinkle like the other stars, but which shone
with a steady light. To these gods the ancients gave
names and personalities. Stories of intrigue and very
human excesses surrounded these gods whose whims were
responsible for all manner of catastrophe, from floods
to impotency. Groups of stars became people and animals
(like the hunter Orion and his two dogs), with those
along the equatorial plane (the band that most of the
planets travel along in our sky) becoming signs of the
zodiac, supposedly moulding our personalities at birth.
As time passed, the study of the motion of the stars and
the other glowing bits of flotsam and jetsam in the
night sky became one of our oldest sciences, with the
ancient civilization of Babylon (present day Iraq) being
the first, around 4,500 years ago, to keep astronomical
records. The Chinese also kept meticulous records of the
appearance of comets and supernovas (exploding stars)
which have been hugely helpful to modern astronomers in
pinpointing past astronomical events. The first recorded
sighting of Halley’s comet, whose orbit makes it visible
to us every 76 years and which we last saw in 1986, was
made by the Chinese in 240 BC.

Getting up close and personal
The best place to look at the night sky is at an observatory.
Here a telescope with a much larger magnification than the sort
you could normally buy is housed, and may be open for public
viewing. Here in New Zealand there are three major observatories
– The Stardome in Auckland, the Carter Observatory in
Wellington, and the Mount John Observatory overlooking the
shores of Lake Tekapo in the South Island.
|
The
Stardome
The Auckland Observatory and Planetarium – better known
as the Stardome – is situated in One Tree Hill Domain
with quick entry just off Manukau Road.
There are public shows in the planetarium almost every
night that recreate the night sky beautifully, with
viewing through the telescope afterwards, weather
permitting. As well as these shows there are extra ones
that often follow a theme – educational as well as fun –
such as Celestial Navigation, which shows you how to
navigate using only the sun and the stars, or SETI (the
Search for Extraterrestrial Intelligence).

Special shows run during the day in the school holidays,
as well as the evenings, for the kids.
Andrew Buckingham at the observatory has Astronz
Dobsonian telescopes on hand, which don’t have many
bells or whistles but which give good quality, high
magnification viewing. Andrew says they are
robust, easy to use, easy to move, set up and dismantle
and also help beginners find their way around the sky as
they don’t have expensive tracking, which teaches kids,
especially, how to use star charts.
There are also some wonderful astronomy programmes for
computers, and Andrew stocks the shopwith what he
believes to be the best available – the Starry Night
collection.
The Auckland Observatory and Planetarium – better known
as the Stardome – is situated in One Tree Hill Domain
with quick entry just off Manukau Road.
As
if that wasn’t enough, they also cater for events from
kids’ birthday parties to corporate functions.

The Carter Observatory
Situated in the beautiful botanical gardens in Wellington – take
the tram from the main shopping centre and wander through the
gardens for an extra treat. The Observatory is open every day
except Christmas, and has an excellent planetarium in operation,
as well as solar viewing during the day, and night viewing. As
with its Auckland cousin, there are regular programmes each day
as well as theme events and specialist programmes.
John Field, head of education at the observatory, says the shop
is well stocked including computer programmes, although these
are less comprehensive than the Starry Night ones – but also
cost considerably less. He also sells Dobsonian telescopes but
they will need to be ordered in.
Again,
kids’ parties and corporate functions are popular as well.

Mount John University Observatory
Overlooking beautiful Lake Tekapo and Tekapo village in the
breathtaking McKenzie Country, the Mount John Observatory
certainly is our most spectacularly placed observatory.
Unfortunately, the telescopes are not available for public use;
instead they are used solely for study and research. The
University of Canterbury oversees this facility and recently
Canterbury, Auckland and Victoria Universities along with Nagoya
University in Japan installed a new 1.8m telescope there.
Earth and Sky Tours operate day and night tours through the
observatory where there is a café and viewing of the
crystal-clear night sky with smaller telescopes. More
information on this can be gained on the Tekapo Tourism
website.

Telescope Options
|
When looking to buy a telescope you basically get what
you pay for. A good pair of binoculars is a much better
option than a small telescope of the same price. While
one is an optical instrument, the other is basically a
toy. In the world of telescopes big is definitely better
– the bigger the magnification, the more you will see.

At the Carter Observatory and the Stardome
the biggest seller is the 8" aperture (the width of the
aperture) Astronz that sells for around $800. An Astronz
with 12" aperture costs around $1800.
For an 8" model with more features you’ll
probably pay around $1200 but it can be much more. The extra
cost is for some sophisticated extras such as equatorial
mounts, which make it easier to track objects as the earth
rotates. (The earth is slowly spinning in space and so the
moon, planets and stars will move fairly quickly out of
vision under a high magnification.) Special mounts make it
easier to track objects manually and a computerised tracking
system is even easier, but these all come at a price. Shop
around.
Something else to consider is how cumbersome
a telescope is to move and set up. It will probably relate a
lot to how often you’re going to use it, especially as a
beginner. |

There are several shops that carry different makes and models of
telescope with Meltzers in Auckland specialising in this field
and camera shops like Camera and Camera having a good range.

Astronomy Clubs and Societies
Joining an astronomy club is a great idea even before you buy a
telescope as members will be able to give you first-hand advice
on what equipment or feature to get or not to bother with. Both
the Stardome and Carter Observatory websites have links to the
different societies and clubs around the country. Many of these
clubs have viewing nights, talks or weekends away and it’s a
great way to get in touch with other like-minded adults and
children.
Astrophotography
If you didn’t have enough reason to invest in a telescope here
is another goodie. Many cameras can be fitted to telescopes and
with the computer software options with photography and image
manipulation, the universe is at your fingertips!
For some people an interest in celestial goings-on may simply be
in a visit to an observatory for an occasional public show. For
others a glimpse into the awesome realm that is the universe may
set in motion a lifelong interest in the origins of all life,
the almost incomprehensible enormity of the ‘big picture’ and
its occupants, and a greater appreciation of our own unique, but
fragile, tiny ball of paradise (the Earth) in its midst.
