Buy the Best Refractor or Reflecting Telescope that You Can



Are you just caught up into the amazing hobby of gazing and observing the heavens? Do you already have your own telescope to use for your nightly star gazing? If you are a budding hobbyist in the field of astronomy, certainly you should not in any way be having thoughts of buying a toy telescope. You should at least purchase for yourself a simple beginner telescope, such as a refractor or reflecting telescope.

Buying those toy scopes is a big no-no as this would only indicate that you are not serious in your star gazing hobby. Of course, later on, as you become really into this astronomical endeavor, you will have to replace your basic refracting or reflecting telescope with one that is more sophisticated and advanced model, which makes for a more exciting stargazing and research.

Remember, even as a newbie in this endeavor, one must shun away from those inexpensive toy scopes, especially the ones offered in department stores. To buy a telescope that is obviously a toy is simply a worthless exercise and the output that you will get is certainly less than impressive. Simply put, buy only the best astronomical telescope possible. (Image credit: tripletlads)

Optical Telescope: Choosing the One that's Best for You

Ever since the ancient times of Galileo, people have been utilizing the optical telescope up to the bright starry skies and looking beyond the Earth into the other worlds. Stargazing indeed can be a rewarding pursuit. You are also given the chance to meet up amateur astronomer friends as star gazing clubs abound with people of similar astronomical interests like you.



First of all, if you are really serious in your pursuit of stargazing, the time to have your own optical telescope is now. It can be the simplest scope brand or the well known Meade telescopes. But how do you go about choosing your own scope? You can try checking on the magnification as this is one significant property of a scope.

However, one important telescope capability is to be able to gather light for what good will a big image do if it can’t be clearly seen? Likewise, in the case of magnification, you can always adjust your scope’s magnification via the usage of various eyepieces, and so while it can be considered; it is actually not of great importance with buying your own stargazing device.

The capacity of an optical telescope to gather light is in direct relation to the scope’s aperture size or its mirror or lens. If you think that you now need a scope with the biggest aperture, then this is not what we need. There must actually be a balance between the portability and the aperture’s size. This balance is what you must look for in a telescope. So, if you are one who needs to move your optical telescope, then you would have to choose one which is not too heavy to be easily mobile.

Choosing your own type of optical telescope depends on your stargazing requirements; everything actually is dependent on whatever plan you might have in using your scope. Of course, the available budget is of primary importance. The good news is that there are many well-known telescope companies such as Meade telescopes which offer great scopes at reasonable prices.

Spitzer Space Telescope: Infrared Observatory

Spitzer Space Telescope – also known as Space Infrared Telescope or SIRTF is actually a space infrared observatory. It is recognized as the final (fourth) Great Observatory of NASA.

The planned duration of the nominal mission was 2 and half years, while its pre-launch expectation is that the mission might have an extension of at least 5 or up to the time when the supply of liquid helium was exhausted. This is projected to happen in April of 2009.

In observance of NASA traditions, the telescope was eventually renamed after a successful space operation on 18th December 2003. And unlike most other astronomical telescopes which are given the names of deceased astronomers and space scientists, Space Infrared Telescope’s new name was derived from a contest that was conducted primarily for the general public.

Spitzer Space Telescope’s name was obtained after that of Lyman Spitzer, the first doctor and scientist who suggested putting astronomy telescopes into outer space.

Nice Look at Galileo Telescope

Were it not for the Galileo Telescope, astronomers and space scientists all over the world would not have enjoyed all the benefits that they can obtain from the refracting telescope – in terms of astronomical researches and observations. Yes it was eyepiece and optics piece creators Zacharias Janssen and Hans Lippershey who invented the refractor, yet it was the great Italian astronomer and scientist Galileo Galilei who worked further on the instrument, managing to increase its magnification for more power. The renowned scientist, with his knowledge of the principle of refraction, did create his scope into becoming the world’s first working astronomical telescope. Above is a photograph of Galileo Telescope, which became the model for the succeeding professional refracting telescopes. Without a doubt, it was the scientific device that changed wholly the astronomical world.

Awesome Hubble Telescope Contributions


Hubble Space Telescope is undoubtedly the most popular astronomical telescopes that are in existence today, if only because of its great discoveries as well as the amazing Hubble telescope pictures that have awed both the astronomers and the public as well.

The Hubble Telescope has greatly contributed to the advancement of the science of astronomy. It has been a major instrument in making land breaking (or perhaps space breaking?) discoveries, providing answers to many questions, puzzles and problems involving astronomy.

One of the more important contributions of the Hubble Space telescope was its accurate measurement of the distance of Cepheid stars, and because of this, the Hubble Constant’s value was contrained. (Hubble constant is the measurement of rate of the Universe’s expansion.

Another very significant contribution of the Hubble Telescope is that it has become an important factor in estimating the age of our Universe. The extreme importance of the findings of Hubble on this regard proves the great efficiency and reliability of this astronomical telescope as a major (and we can say indispensable) means of uncovering the secrets of the Universe.

We can only appreciate the existence of the Hubble for its unparalleled contributions to space and the astronomical science. And as we enjoy the Hubble Telescope pictures, we might likewise want to thank it for allowing us to see the Universe, even if just in pictures, for all its magnificence and greatness.

Seeing Hubble Telescope in Space

I am able to come across this short documentary about the Hubble Space Telescope. The clip shows the travel of the Hubble on its orbit around our planet Earth at 5 miles per second. Again, we are shown how powerful and effective the Hubble Telescope is compared to other land based astronomy telescope. Because of this amazing space astronomical telescope, astronomers and scientists were able to correct astronomical facts that were previously believed in such as the discoveries of groups of galaxies which were once thought of as lights and gases that graze the expanse of space. The Hubble Space Telescope gives us the chance to understand more about our world and the solar system that it belongs to while having the great opportunities to explore other worlds apart from our own.

Amazing Telescopes by Meade

Meade telescopes are the flagship product of the Meade company, which was founded by John Diebel in 1972. Actually the company started as a small mail-order company selling refracting telescopes and accessories.

Then Meade also sold reflecting telescopes and Schmidt-Cassegrain type afterwards. Gradually the Meade telescope company became a worthy competition to Celestron Telescope company. Today, the Meade is considered one of the largest scope producers and manufacturers in the world.

Most usually have equatorial and alt azimuth scope mounts, with computerized locator of space objects. Other Meade telescopes have scope mounts that will automatically aim at any astronomical object. This kind of high technology feature is what you all “GoTo.”

Meade Accessories

One of the more amazing telescope accessories is the 5000 series eyepiece. This is quite similar to that of Tele Vue Optical’s 82 degree field-of-view Nagler eyepiece and as well as the Radian eyepiece, which as a 60 field-of-view degrees.

Low cost scopes by Meade

The company also has on its inventory some low priced imported Meade starter telescopes such as refractors and reflectors. These are intended for the huge market of new hobbyists and starting astronomers.

2004 Acquisition by Meade Telescope

In 2004, the company was able to acquire Coronado Filters, a company that creates and produces a wide variety of specialty astronomical telescopes. One feature of this scope is that it permits sun views under the wavelengths of Hydrogen-Alpha and Calcium K line.

Hubble Telescope Unveils the Universe

If you need the most awesome pictures of the Universe and space, then the photographs taken by the Hubble Telescope prove to be the best references. Clear images of the planets, stars, galaxies and constellations have already been produced by the Hubble Space Telescope throughout the years.

Such amazingly vivid pictures are major data and evidences in themselves; they are very useful in unraveling the many secrets and baffling truth, as well as the mysteries that shrouded our Universe for the longest time.

Galaxies and other space entities that were barely visible and even blurred in previous photographs are now better studied and closely scrutinized because of Hubble’s excellent quality pictures.

Whereas before, when needed to measure the distance between stars prove to be a very difficult task even with the use of the most powerful earth-based astronomical telescope, it has now become easier to accomplish with the use of the Hubble Space Telescope. And such measurements are very precise that the telescope is now regarded as an indispensable device of modern astronomy.

Indeed, this space telescope is not a great tool in major astronomical applications and has become a key in unlocking many queries in astronomy that for a long time remained unsolved (until now), and continues to be one.

Here is a video I got from youtube on the many discoveries of the Hubble Telescope:

Hubble Space Telescope: A Great Satellite


Since the Hubble Telescope is circling the earth on its orbit, is it considered a satellite too – just like the moon?

It puzzles me on whether the Hubble Space Telescope is a satellite or not, so let us first define the meaning of the word.

The very first time I got acquainted with the word satellite was in the phrase “weather satellite,” as it was frequently mentioned in most evening news programs.

Then there was the Russian Satellite Sputnik, which was considered an artificial space object actually meant to orbit the planet Earth.

So, this means that a celestial object or body circling or orbiting the earth (usually the case) or any other large space body is considered a satellite.

So again, is the Hubble Telescope also one? Primarily a celestial astronomical telescope, the Hubble Space Telescope observes the Earth and its atmosphere, as well as other space objects as it orbits around the planet.

Therefore, aside from the fact that it is an astronomy telescope that makes scientific observations and takes space pictures, it can also be said that the Hubble Telescope is a satellite, an artificial one at that. (Photo Credit: NASA)

Ceres and Vesta Through the Hubble Space Telescope


Ceres and Vesta are two of the most popular bodies in the solar system – and they are also the two of the largest asteroids. Unfortunately, clear photographs of these heavenly bodies are difficult to produce, until recently by the Hubble Telescope.

The pictures of the two asteroids using the Wide Field Planetary Camera of the Hubble Space Telescope are needed for the long term observation mission by Dawn Robotic Space Craft. This is the first time that a close observation of the two asteroids will be done in one mission.

Ceres, the larger asteroid was previously thought of as a planet. Now it is labeled a dwarf planet according to the International Astronomical Union.

Vesta on the other hand, is more irregular in shape and has a prominent crater feature on its South atmosphere.

Early images of the two from astronomical telescopes showed multitude of colors, suggesting volcanic activities on the surface.

Better photographic results from Hubble Telescope

With the larger, clearer photographs of Ceres and Vesta by the Hubble Space Telescope, with results a thousand times better than any other land based astronomy telescope, more significant information on the asteroids will be discovered and certainly will be considered a major link to the creation of our solar system.

Radio Telescopes: In Search of ET's


When we mention about refracting telescope or any other astronomical telescope for that matter, we always think about how images from space such as that of the moon, planets, solar system and even far beyond can be clearly seen. And really a thousand times better than if you are going to use your naked eye.

Telescopes in fact are meant to study the universe and what it has been and become for billions of years. In fact, the images that you might have been observing from your peek through an observatory telescope are millions and millions, even billions of years old.

But what about the search for ET’s or aliens on outer space. Are telescopes also capable of finding or detecting any intelligent life that’s present anywhere in the universe? Surely your refractor or reflecting telescope is not equipped to find one even if you train it up the sky 24 hours a day.

Actually there is one that’s intended to look for ET’s – and this is the radio telescope. By the way, there is what we call SETI, the acronym for search for extraterrestrial intelligence. This phrase was coined as the pursuit of scientists and astronomers to search for alien beings intensified.

There are some radio telescopes that exist with the main purpose of detecting and identifying alien life forms. Two of such scopes are the Allen Telescope, found in California and the Arecibo telescope in Puerto Rico. Hopefully, with the sheer power of these telescopes working non-stop every minute of the year, success of finding a life form other than our own will become a reality.
