TELESCOPES

Reflecting Telescope Information

When viewing distant objects through the use of a telescope, the most important part of that telescope is called the objective. The objective is that component of the telescope that has the ability of gathering the light that is available. Obviously, the larger the objective the greater is the capacity of the telescope to gather light which in turn allows the viewed image to be better visualized.

In addition, there are two types of telescopes. One type of telescope is called the refractor telescope and the other is known as the reflecting telescope. The difference between these two telescopes is how the light is captured.

Celestron – PowerSeeker 127EQ Telescope – Manual German Equatorial Telescope for Beginners – Compact and Portable – Bonus Astronomy Software Package – 127mm Aperture

Refracting and Reflecting Telescope

The refracting telescope obtains the light through its objective that is made out of glass. Basically, in this type of telescope, the glass lens is situated towards the front of the telescope. As the light is captured by the objective, it is then refracted or deflected through a lens which allows for the viewed image to be magnified. Examples of this type of telescopic equipment include scopes that are used on rifles, binoculars and spyglasses.

A reflecting telescope uses a mirror as its objective. This mirror is located towards the distal end of the telescope. In addition, the mirror has a concave shape. The curvature of the mirror allows for the midpoint of the mirror to be the focal point for all of the light that strikes each part of the surface of the bowl-like mirror. This reflection is then captured by the lens to view the item of interest.

Advantages Of The Reflecting Telescope

NATIONAL GEOGRAPHIC Explorer 114mm Reflecting Telescope

There are several advantages to the use of a reflecting telescope. The major advantage is that distortion of what is being viewed is minimal. This is because, through the use of the mirror, the wavelengths are all reflected consistently. This advantage also leads to the reflecting telescope being less expensive than the refracting telescope.

In addition, through the use of the mirror as the objective, the support for this mirror can be all along the posterior portion of the telescope. This allows for the housing to be very large which will accommodate a larger mirror. Larger mirrors mean more light which results in increased visibility.

Disadvantages

However, as with anything else, there are a few disadvantages in the use of a reflecting telescope. One of those disadvantages is size. This is due to the fact that these types of telescopes can accommodate larger mirrors. This results in the telescope itself being larger which may prove to be an issue when storing or relocating the reflecting telescope.

In addition, because of the use of mirrors, there may need to be occasional adjustments made so that optimum light alignment is maintained.

The World Of Refractor Telescopes

Refractor telescopes are some of the oldest telescopes available, utilized at around the beginning of the 15th century and still around today the refractor telescope is quite possibly one of the oldest telescopes in use today. Made up of concave lenses that allow the light to be refracted and images to appear bright and larger than looking at it with the normal eye the refractor telescope can greatly aid in seeing stars, planets and moons.

These telescopes are made up of convex lenses and an eyepiece lens similar to binoculars, these refractors gather light and bend it in order to view objects at a distance, which is particularly useful when looking at stars and the night sky Refractor telescopes may seem complicated and are made up of lenses that are concave and refract the light.

The telescope come in a variety of versions; the Galilean telescope which is named after its creator was one of the first versions and was improved upon by Johannes Kepler with the Keplerian Telescope, which is a refractor telescope that utilized a convex eyepiece as opposed to a concave of the Galilean model. The decades and centuries since have observed newer inventions and different lenses, with the achromatic refractors invented in the mid 16th century and later with apochromatic refractors.

Pros and Cons of Refractor Telescopes

Telescope for Kids & Adults – 70mm Aperture 500mm AZ Mount Fully Multi-Coated Optics Astronomical refracting Portable Telescopes, with Tripod Phone Adapter, Carrying Bag, Remote Control

I stated previously that refractor telescopes have been around a long time and with that comes a definite plus since there is a definitive ability to know what the pros and cons of the telescope. These telescopes have obviously come a long was since the 15th century yet the technology has increased to a point in which the refractors have improved yet the size of refractor telescopes pose a problem in the fact that the larger the refractor lens the more chance that it can have defects or begin to sag.

While technology continues to grow and there is no telling where refractor lenses in telescopes will go to in the future one thing for sure is that refractor telescopes have been around for centuries and thus show no decline in their use by many of astronomers. So no matter what telescope you choose to utilize to view the universe or neighborhood, you can not dismiss the value of the refractor telescope and the impact that its utilization has had on astronomy and the search of the skies.

Shooting Stars

If you are a serious astronomy fanatic like a lot of us are, you can probably remember that one event in childhood that started you along this exciting hobby. It might have been that first time you looked through a telescope. But for many of us, it was that first time we saw a rain of fire from the sky that we eventually came to know as a meteoroid shower.

At the time when you see the first one, it’s easy to remember the movie “war of the worlds” or some other fantastic image of aliens entering our atmosphere in droves to take over the planet. But with some guidance and explanation of what was going on, we eventually learned that these showers were not at all threatening or any kind of invasion. For the most part meteoroid showers are harmless, part of nature and very fun to watch.

So what are these strange lights in the sky? Are they aliens invading from Mars? Are the comets coming to start the next ice age? Or perhaps asteroids burning up as they enter the earths atmosphere. The answer to the above questions is no to the first and “yes and no” to the other two.

A meteoroid is actually a small piece of space rubble, usually dust or small rocks that come from either a comet or the break up of an asteroid in space and that eventually plummets toward the earth. We say “toward the earth” because the lights you see are the friction of the atmosphere burning up those small space tidbits and creating a spectacular show for all of us as they do so. A particularly exciting moment to witness is when a meteoroid breaks up or explodes on entry. A meteoroid that explodes is called bolides.

There are some interesting details about the life of a meteoroid that make the viewing of shooting stars even more fun. To be seen, a meteoroid only needs to weigh as little as a millionth of a gram. But the thing that makes them so spectacular to see is the tremendous speeds they reach as they enter the atmosphere. Before burning up, a meteoroid will reach between 11 and 74 kilometers per second which is 100 times faster than a speeding bullet.

We tend to think of seeing a shooting star as a freak event and we associate it with superstition (hence, wish on a lucky star). But there are actually thousands of them every year so it really isn’t that rare to see one. In fact, scientists tell us that over 200,000 tons of space matter enters the atmosphere each year and burns up on entry.

Comets are a big source of meteoroids because of the nature of those long tails. A large amount of dust, ice and other space debris gets caught up in a comet’s tail as it moves toward the sun. Then as the comet moves away from the sun in its orbit, tons of this matter is thrown off into space to disperse. As the Earth moves in its routine orbit around the sun, it often crosses through clouds of this discarded matter which becomes one of those “meteor showers” that are so popular for viewing.

These showers of shooting stars are pretty easy for astronomers to predict so you can get into position to see the excitement at just the right time of night and be looking at the right area of the night sky. Usually the astronomy magazine or site will give you a general time and location to be ready to look when the meteoroids start to fall.

Now keep in mind, this is a phenomenon of nature, so it may not observe the time table exactly. Also note that there is a notation system for where the meteoroid shower will occur based on what constellation is its backdrop. The section of the sky to focus on for the show is called the “radiant” because that is where the entering meteoroids begin to glow or radiate. The radiant is named for the constellation it is nearest too. So if the meteor shower is going to occur in the constellation of Leo, then its radiant will be called Leonid. This will help you decipher the listing of asteroid showers in the publications.

The one thing we love the most in the world of astronomy is a good mystery. And if there was ever a mysterious and yet very powerful force of nature that we witness in the night skies, it is the coming of the mighty comet.

The arrival of a comet within view of Earth is an event of international importance. Witness the huge media attention that the Haley or Hale-Bopp have had when they have come within view The sight of these amazing space objects is simultaneously frightening and awe inspiring.

Above all, it is during these comet viewings that the astronomer comes out in all of us. But what is a comet? Where did it come from? And how does it get that magnificent tail?

We should never confuse comets with asteroids. Asteroids are small space rocks that come from an asteroid belt between Mars and Jupiter. While still quite stunning to see, they pale in comparison to the arrival of a comet. Asteroids also have received considerable study by the scientific community.

Not as much is known about comets. As a rule, comets are considerably larger than asteroids. The composition of a comet is a mixture of nebulous, gasses, ice, dust and space debris. One scientist called the composition of a comet as similar to a “dirty snowball” because the composition is so diverse and changeable. The center or nucleus of a comet is usually quiet solid but the “snowball” materials often create a “cloud” around that nucleus that can become quite large and that extends at great lengths behind the comet as it moves through space. That trailing plume is what makes up the comet’s magnificent tail that makes it so exciting to watch when a comet comes within view of Earth.

The origins of comets is similarly mysterious. There are a number of theories about where they come from but it is clear that they originate from outside our solar system, somewhere in deep space. Some have speculated they are fragments left over from the organization of planets that get loose from whatever gravitational pull and are sent flying across space to eventually get caught up in the gravity of our sun bringing them into our solar system.

Another theory is that they come from a gaseous cloud called the Oort cloud which is cooling out there after the organization of the sun. As this space debris cools, it gets organized into one body which then gathers sufficient mass to be attracted into the gravity of our solar system turning into a fast moving comet plummeting toward our sun. However, because of the strong gravitational orbits of the many planets in our solar system, the comet does not always immediately collide with the sun and often takes on an orbit of its own.

The life expectancy of comets varies widely. Scientists refer to a comet that is expected to burn out or impact the sun within two hundred years as a short period comet whereas a long period comet has a life expectancy of over two hundred years. That may seem long to us as earth dwellers but in terms of stars and planets, this is a very short life as a space object indeed.

Scientists across the globe have put together some pretty impressive probes to learn more about comets to aid our understanding of these visitors from beyond. In 1985, for example, the United States put a probe into the path of the comet Giacobini-Zinner which passed through the comets tail gathering tremendous scientific knowledge about comets. Then in 1986, an international collation of scientists were able to launch a probe that was able to fly close to Haley’s comet as it passed near Earth and continue the research.

While science fiction writers and tabloid newspapers like to alarm us with the possibility of a comet impacting the earth, scientists who understand the orbits of comets and what changes their paths tell us this is unlikely. That is good because some comets reach sizes that are as big as a planet so that impact would be devastating. For now, we can enjoy the fun of seeing comets make their rare visits to our night sky and marvel at the spectacular shows that these visitors from beyond put on when they are visible in the cosmos.
