This is due to the fact
that the ground around the telescope is heated up by the sun
during the day and this results in turbulence
which affects the quality of the picture produced. This is why large
scale solar observatories are built high off the ground or have other
aspects of their construction which allow them to stay cooler and thus
produce a much higher quality image of the sun.
Solar observatories are
always built on a tall structure that is painted white to reduce the
amount of heat it absorbs. For smaller, personal sun telescopes it is
possible to use them in areas which are shaded to reduce the amount of
turbulence and ensure that you receive a clearer picture. Heat is also
a problem for solar observatories in a different way.
Solar observatories use
large mirrors to concentrate and focus the sunlight, which thus creates
a large amount of heat not unlike the heat created by a solar
concentrator. However, unlike a solar concentrator which uses the heat
to create energy, a solar observatory must somehow deal with all the
heat to keep it from damaging the device itself.
It is also essential to
stopping the heat from causing any additional turbulence in the air
around the telescope. This is why all solar telescopes contain a heat stop, which is
a device that allows the device to survive the amount of heat created
by the focused sunlight.
Even the small personal
devices contain a heat
stop albeit a much smaller one as much less heat is created when using
a smaller lens.
Most sun telescopes work
based on a heliostat
which is a device that allows the telescope to precisely track the sun
during the day. This way the lens can stay focused on a particular part
of the sun, such as a sunspot or solar storm. Even personal units track
the sun, usually with the aid of the computer that it is connected
Using Personal Solar
Telescopes to View the Sun
If you are interested in
solar activity, then purchasing a sun telescope is by far the best way
to view this activity. While this requires an investment of at least a
few hundred dollars, it is still well worth it for those who really
want to view all of the amazing solar activity.
If you’re considering
purchasing a solar telescope, it is essential that you do adequate
research to ensure that the product you are buying is of the highest
quality and best value. There are hundreds of different products on the
market, each claiming to be the best telescope that money can buy.
Unfortunately they cannot all be the best.
That's why we have done
some of the research for you, and below we have listed two of the
better telescopes that you can get without
having to break the bank.
Both products are made by highly reputable manufacturers, and are quite
easy to use and more than adequate enough for most solar enthusiasts,
but the best thing about these two products is that they are in the
end of the price range for high quality solar telescopes.
Celestron Travel Scope 70
Celestron is one of
leading producers of telescopes and other astronomical devices. They
produce very high quality products, and the Travel Scope 70 is no
different. This small, lightweight telescope is very portable so you
can take it anywhere with you to view the solar activity happening on
the surface of the sun.
However, the best part of
this product is that it retails for under $60, making it one of the
most affordable sun telescopes on the market. This is a
telescope that comes with a tripod
and a white light solar
filter, and is
easy to point and focus on objects.
21035 70mm Travel Scope is a
great scope for
beginners, or those not looking to spend a few hundred dollars on a
higher quality product.
iOptron Solar 60
If you are looking
more technologically advanced, automatic sun telescope, then the
iOptron Solar 60 is the product for you. This product is a fully
computerized telescope that comes with a 1.3 megapixel electronic
eyepiece that can be connected to your computer with a USB
also includes a controller with a 5000 object database, so you can
simply pick the object and the telescope with find it and focus on the
object. It can be used day or night, so it is both a solar and normal
This device is slightly
heavier than the Celestron, but it still weighs less than twenty
pounds, and even comes with a matching orange backpack to make it very
easy and convenient to take around with you.
This is by far one of the
best computerized solar telescopes that you can get, and at a price of
around $400, the iOptron
Solar 60 is much
cheaper than many of its competitors, and
our personal recommendation.
