The word astronomy is comprised of two Greek words. The Greek word astro means star shaped or star and pertains to outer space. The word onomy literally means the study of. Therefore, astronomy is the study of the stars.

One of the major tools that assists amateur and professional astronomers in understanding and respecting the galaxy is the astronomy telescope. When looking to purchase a good astronomy telescope there are a number of factors that you can keep in mind. First, of all consider some practical suggestions, remember it is about the diameter of the lens, and make sure your telescope has a solid stand.

Practical Suggestions

Before you purchase your astronomy telescope it is important to conduct your research. One way of conducting this research can be accomplished by accessing the Internet and learning more about telescopes. Some of the questions that you should endeavor to answer surround what features to look for in a telescope, approximate cost, recommended brands, etc.

Another practical suggestion, before you purchase your astronomy telescope, is to "test drive" a telescope. This can be accomplished by joining an astronomy club. Often these clubs will have a stargazing event which will allow you to peer through the telescopes owned by the various members.

Another way of conducting research, prior to purchasing an astronomy telescope, is to ask the members in the club as to what telescope they would recommend. The key is education. Listen for the features they recommend, brand names, the diameter of the lens, price, etc.

Also, you may come across a member of the club who is considering the purchase of a new telescope. If so, you may be able to purchase their used telescope.

Diameter Of The Lens

When considering the purchase of an astronomy telescope it is important to remember what is the key feature surrounding your purchase. That key feature should focus on the diameter of the lens of the telescope and not its advertised magnification.

This is because the diameter of the lens equates to the amount of light that can be received by the telescope. Therefore, the larger the diameter of the lens the more light that is captured. This in turn allows for the image that you are viewing to become more visible.

Solid Base

Another very important feature when considering the purchase of your astronomy telescope is to ensure that it has a solid base. Generally, these bases or mounts are tripods.

It is important that when the telescope is mounted on these bases that the telescope does not shake or move. Obviously, any movement by the telescope, when peering into space, will distort the image being viewed and provide a negative experience.

Buying Your First Astronomy Telescope is a post from: Meade Telescopes

Children and adults everywhere find the night sky fascinating and love to make wishes on the stars they see. As children get older, they begin to learn about what is in the night sky and many develop an interest in astronomy.

Astronomy is a word from the Greek language. Astro, the first part of the word, comes from the Greek word for the star shape and also refers to outer space. The last part of the word, onomy, is Greek for "the study of". So from the original Greek, astronomy means study of the star or outer space.

Novices and experienced astronomers need one main tool to learn about and enjoy the night sky: an astronomy telescope. There are many different kinds of astronomy telescopes. You need to choose carefully and consider some important aspects of the telescope, such as the size of the lens and the sturdiness of the telescope stand, when you are looking to buy your first telescope.

The Importance of the Lens Diameter

Certain aspects of your new astronomy telescope will either make it enjoyable or leave you frustrated. Lens diameter is one of these aspects. Forget about magnification; the size of the lens of the telescope is more important. The larger the lens diameter, the more light it lets into the telescope and that affects how well you can see the things you are trying to look at in the night sky. The brighter the light, the clearer the images will be.

Choosing a Good Astronomy Telescope Stand

You will want to give a lot of thought to the type of stand you mount your new telescope to so that you get the most efficient use out of your telescope. A good tripod stand is the way to go. You want to choose a stand that will keep the telescope still so you get the best views of the night sky. Any movement at all will make the images you see blurry and cause you frustration.

Where and How to Shop for an Astronomy Telescope

You need to find out what your options are and know what the different telescopes offer before choosing one. One of the easiest ways to gather information about telescopes is by looking online. You should try and find out what the features are that are offered on each kind of telescope, how much they cost and what reviewers think about the different brands of telescopes.

One way to choose a good astronomy telescope is to try some of your potential telescopes out. If there is an astronomy club in your local area, you might be able to join and meet people who share your hobby. Then, you can try a variety of different telescopes to see which ones work for you.

You can also get a lot of useful information to help you choose an astronomy telescope by talking to people who are in astronomy. Your friends and family members who have astronomy telescopes can tell you what they like and dislike about theirs. If you have friends or family involved in astronomy, you might ask them to let you know when they are replacing their telescopes so you can possibly buy their old one from them.

Telescopes for Sale for Budding Astronomers is a post from: Meade Telescopes

When two lenses are combined together, they are able to collect more light than individual lenses. This is the main principle behind Galileo’s telescope. Most of the telescopes in use today, use the same principle. The human eye also works on a similar principle, but cannot collect too much light. Telescopes are able to gather more light because of the double lenses used in its construction. These lenses gather light and build an image by focusing the light at a point. Refraction is the mechanism in use to form such images. As a result, telescopes are also called refracting telescopes or refractors. The phenomenon by which the collected light bends and forms images is known as refraction.

Images were magnified by a factor of 30 in Galileo's invention. However, the shape of the lenses he used was such that his image became blurred and distorted. But no one had ever invented something so exciting with which to observe the night skies before Galileo's telescope. Galileo used his telescope to view the moon and observe it closely. He was also the one to figure out that the magnification factor of a telescope was provided by the ratio of the power of the concave lens to the power of the convex lens. So he premised that the simplest way to increase this magnification factor was to use a high power concave lens with a weaker convex lens.

In Galileo's time, there were only low strength lenses available. Due to this restriction, Galileo decided to make his own lenses. He was soon able to achieve a magnification of 9x with lenses hat he had ground himself. His telescope was fitted with his own lenses. It was just another feather in his already well-decorated cap.

As time passed, Galileo improvised on his primitive telescope, making several modifications to it. He also demonstrated his invention at the Senate of Venice, and several senators climbed the highest towers of the time to observe the horizon with Galileo's invention. They viewed the distant ships from their perches and decided that the telescope was a very useful military device.

The telescope changed the face of Astronomy and became an indispensable part of the study. Several inventors used the same principle and made telescopes of their own. Gradually over the years, the study of astronomy benefited immensely from the telescope and its uses. The same principle was employed in the construction of much more powerful telescopes that made it possible to understand our plane and its surroundings more comprehensively, all thanks to Galileo's wonderful invention.

How to Use a Telescope – Galileo’s First Telescope and Its History is a post from: Meade Telescopes

A big problem facing most astronomy telescope owners is that of how to find objects in space. It is easy to find the Moon, you can't miss it! But, what about Pleiades or Andromeda?

For centuries, to find anything in space, required a knowledge of the position of the objects that astronomers wanted to find. Though this is easier to find out this data today, it still is not the easiest of things to do, even with the information.

For example, conventional telescopes with a mount such as the equatorial mount works with having the telescope calibrated with the pole star, then using the telescope to maneuver to the coordinates of the object you seek to find.

As you can see, this process can be long, and requires a bit of learning. This can be great, especially if you want to learn how things work, but if you simply want to have the visual enjoyment of viewing objects in the heavens, this can be a bad point to astronomy and using a telescope.

Over the last few years, a new type of telescope has been created, and put to market. That is the computerized GPS telescopes, and they offer something new. Instead of having to figure out coordinates, and positioning a telescope to view something, instead you have a computer on the telescope do it!

Companies such as Meade telescopes and Celestron telescopes manufacture great 'GoTo telescopes'. And they come equipped with a database of 10's of thousands of objects. Needless to say, if you want a telescope simply to view objects in space, a computerized telescope could be your best move.

If you want to find Saturn for example, you type it in, and the computer controls the motor on the telescope, and within a minute, you have the telescope on position to where the object is!

The other benefit with a computerized GPS telescope is that it follows the objects through the sky, so this can be a great feature, especially if you want to use your new telescope for capturing pictures.

The price point of the computerized GPS telescopes is not that much more different than conventional telescopes. This makes them a good idea to buy. Your choice will come down to what you want out of astronomy. If you want to simply view objects, then computerized could be the best way to go. If you want to learn more about astronomy, and how things work, then a conventional telescope may the best option to buy.

Computerized GPS Telescopes Verses Conventional Telescopes is a post from: Meade Telescopes

::: Knowing the Strengths and Weaknesses of Your Telescope :::

Knowing the good points about your astronomy telescope will help you use your astronomy telescope much better. For example a really heavy astronomy telescope may not be good enough to move around much, as I found with my second astronomy telescope, however the benefit was that the stability of the mount, meant that it was pretty good at keeping steady when looking at objects. Whereas a small astronomy telescope which may have been purchased at a local toy store may not be steady enough for viewing the heavens outside, especially if it is windy outside.

::: Knowing the Heavens :::

I am about the give you some of the greatest advice I can give you. And that is to know the heavens! When I was young, I wanted to get the best astronomy telescope I could. My first telescope was not the best astronomy telescope and in fact couldn't show me anything more than the moon.

Later I found when I purchased a much better astronomy telescope years after, that there was a major situation. Yes, I had the best astronomy telescope, at least compared to my first telescope, but I found a dilemma with being able to find nebula and galaxies.

Looking back I think first learning where things where in the heavens, would have made a much better start in astronomy. Your first telescope may not have a comprehensive manual on how to find objects in the heavens. The best book that helped me learn exactly how to find things in space was Turn Left At Orion.

::: Telescope Care :::

A astronomy telescope is a great instrument. Your first telescope is always an important one - it is your gateway to astronomy, and usually your first glimpse at seeing what the beauty of the universe contains. Your first telescope must be taken care off, if you are to get the best out of your astronomy telescope.

Ways you can keep care of your astronomy telescope is to put protectors back on astronomy telescope lenses when you finish. If you have a metal astronomy telescope which you keep outside, make sure you put it inside when finished. It is far too easy after spending a few hours outside to say I will bring it in tomorrow! Rain may fall on your astronomy telescope which could cause rust, which is not what you want. The best thing you can do, if you must leave the astronomy telescope out is put a plastic cover on the astronomy telescope to protect it. Another tip is to put Vaseline on the astronomy telescope mount and joints so it can be protected from the rain.

Always make sure optics are brought inside as if rain get on them they can easily get damaged. Same as the main astronomy telescope tube if possible. You may also need to clean the mirror if you have a reflecting astronomy telescope, and should always take care to clean the mirror in accordance with the astronomy telescope manuals suggestions.

::: Getting the Best in Astronomy :::

More you learn about where to find objects in space, more you will get enjoyment out of your astronomy telescope. Astronomy is a fantastic hobby, and one which can never get exhausted, especially with 70,000,000,000,000,000,000,000 stars in space (at current counts)!

How to Use your New Telescope for Best Results is a post from: Meade Telescopes

Lots of things to consider! However, there are many options in getting a astronomy telescope for child. The main part of what you want to make sure of, is to get the best astronomy telescope for child that will help him or her have a hopefully life long and fulfilling hobby with astronomy and looking at the stars.

I remember my novice telescope was a department store astronomy telescope. The quality of the astronomy telescope was not much to admire. However, this astronomy telescope was great in igniting my fascination with looking up at the heavens. Though that astronomy telescope was no use to look at anything outside our solar system, the astronomy telescope did help me see the moon, and give me the drive to continue my astronomy hobby till adulthood, where now I have a very nice astronomy telescope and much more powerful then that novice telescope. I have to admit that without that low quality toy department astronomy telescope, I would very likely not have had such a long fascination with astronomy.

My biggest suggestion I can give you however, is if your child is slightly older, consider binoculars instead. The reason being is that one of the biggest frustrations with astronomy is that you get a astronomy telescope which is precise, however, is not one of the best objects for learning where things are in the sky. An aeroplane is great, but without knowing where things are in the world, it would be almost impossible to set forth with a sense of direction.

You may be wondering how good a set of binoculars can be. A set of binoculars offers 2 benefits. One is that it allows seeing land objects and also seeing constellations. A good set of binoculars is much cheaper then a astronomy telescope has good optics and coupled with a good astronomy book, can teach your child about astronomy. This is much better then getting a cheap astronomy telescope for child, which could work against there long term desire at continuing astronomy as a hobby.

However, both options do have there benefit, again it depends on the age of your child. Astronomy at any rate needs patience. Another alternative is astronomy telescopes such as Meade's computerized range of astronomy telescopes. These astronomy telescopes do have the benefit of being easy to use, already has a database of all the stars, and with the push of a button will move to find the object ready for viewing!

For a purist kind of view, a computerized astronomy telescope does not offer the benefits of learning where things are in the sky. The computerized astronomy telescope is a astronomy telescope for child which can be of great value. Especially considering the ease with which to find objects in the night sky. It is as simple as choosing an object to view, keying in the code, and let the astronomy telescope move about to find the object.

Buying a astronomy telescope for a child can be as easy as going to a local department store selling toys and the odd astronomy telescope. However, that is not always the best option, it all depends what you want to accomplish. To set a child on a lifelong hobby with astronomy is to consider the binoculars, however, a computerised astronomy telescope for a child can be as good, by allowing the child the easy ability to key in the object whether Saturn, Mars or Pleiades and have it at once whisked into view.

SLOOH is a robotic observatory on the Canary Islands. Every Monday, whenever conditions permit viewing, you can participate in mulitple SLOOH "missions" over the course of an hour-long session.

What does SLOOH stand for? Apparently it's about putting the OOH into SLEW!

High atop Mount Teide, on Tenerife in the Canary Islands, the telescopes of SLOOH stand nestled among the facilities of a professional astronomical observatory. SLOOH is a subscription-based web site that streams live images of dozens of celestial objects viewed by its telescopes each clear night over the Internet.

SLOOH currently uses several 3-megapixel CCD cameras and four telescopes (in two domes):

• a 14-inch diameter Schmidt Cassegrain Telescope (focal length 2160mm) high magnification scope and and Wide Field Lens System with a focal length of 135mm at f/5.6 in Dome 1
• 14-inch diameter Schmidt Cassegrain Telescope (SCT) with a focal length of 4,000 mm, and an 85-mm diameter APO refractor telescope with a focal length of 480 mm in Dome 2

The organization will soon be adding an additional 14-inch SCT with a focal length of 2,100 mm, as well as a 34-mm diameter refractor with a focal length of 135 mm. Members are allowed to control the scopes from their own computer. Bringing the rhythms and wonder of space exploration to people of all ages, SLOOH's telescopes are the centerpiece of live interactive missions to the wonders of the universe.

The site is good for someone who knows nothing about astronomy and for avid, enthusiastic hobbyists, for first-time observers of all ages and parents wanting to introduce their kids to the cosmos without buying, assembling, and learning to use telescopes. Would-be astronomers can gaze at live images of the night sky, but in the comfort of their homes. The preset missions are broadcast live, with only brief intermissions as the telescopes and CCD cameras are slewed from one celestial body to another.

The annual $49 basic membership package gives you unlimited access to group missions and the ability to log on any time you like during mission hours. This basic package also gives you 15 minutes per year of solo time in which you decide where to point the scopes. While the basic membership has some restrictions, an "all-you-can-eat" option is avaliable for $99 yearly.

To guarantee its visitors only the best experience, SLOOH tests the speed of your Internet connection and accepts only visitors with connection speeds of 40 kbps (40k) or greater.

SLOOH makes extensive use of the latest Macromedia Flash Player, a web-browser plug-in. Before you arrive at your interface, SLOOH checks to see if your browser has the latest Flash Player installed and directs you to download it if you do not.

While missions are running, SLOOH's operators often chat with visitors in the SLOOH Chat Room. You can join them if you have AOL's Instant Messenger (AIM) software installed. This is an optional feature only. For details, you need to click the Chat button on the mission interface.

If you arrive early, the mission will start automatically at the scheduled time. If you arrive while the mission is running, you will join it in progress.

SLOOH also run a Users Group on on Yahoo so you can check out what people have to say about it.

Version 2 of SLOOH went live on March 18th, 2006. A year in the making, this version has been inspired its users' commitment to live astronomy. In addition to existing features, SLOOH 2 offers some bold and novel new elements

that will attract an even greater membership from around the globe.

SLOOH 2.0 is designed to empower its users (from over 60 countries) to share their enthusiasm for

astronomy with the greater public. Foremost among the changes is the new Member Channel, which enables members to broadcast their solo missions to the rest of the viewing membership. A new desktop alert system will also be introduced, which will notify members when special missions are lined up with a live host who will narrate specifically about the celestial object in view.

When you consider the price of buying a telescope comparable in size to those used at SLOOH against the low fees they charge, it's really a no-brainer. And, while it may be cloudy outside, where you live, the skies in the Canaries are virtually guaranteed to be clear. SLOOH can give you your skywatching fix, wherever in the world you live.

Gary Nugent recommends you check out the SLOOH review at http://www.nightskyobserver.com/Articles/SLOOH.php where you can also see photos of the SLOOH interface, the observatory and some sample images taken by the SLOOH telescopes.

Gary Nugent has been involved with astronomy as a hobby, either running astronomy clubs, publishing magazines or writing astronomy software for over 30 years. He runs one of the best-known astronomy and space news websites - the Night Sky Observer [http://www.nightskyobserver.com] which has been online since 1997.

Astronomy & Space Poll?

Do you agree with this?

This is false. It is possible to calculate the mass of any object, whether in eaarth orbit or not. The mass of the earth, moon and sun have all been calculated. one way to calculate them is to apply a force and measure the acceleration.

A few years ago scientist thought they were well on the way to understanding the universe. New tools allowed them to look further and to see more than ever before. One thing that they needed to do is to get some idea of the amount of mass that the universe contained. This should be easy. The matter that we have here on earth is the same kind of matter that shines in the stars. Picking a representative area of the cosmos and getting an inventory of what is visible should give us the answer. Imagine their shock when they found that the normal matter that we all know is only 5% of what the universe contains. A type of matter called dark matter is 23% and the rest is dark energy at 72%. How can we find out about dark matter? We can't see it. As it behaves just like normal matter with respect to gravity, we can find out how much there is by how it influences the normal matter that we can see. It is the motion and speed of the things we can see that tell us it must be there. Dark energy is even harder to pin down. The explanation of why scientist believe it's there is a bit more convoluted, so I'll leave that one up to the author.

One thing that helps us find out about dark matter is Einstein's telescope. We have much better telescopes and other instruments today than we ever had but Einstein's telescope is not one that we can build. Einstein's theory told him that when light from an far object in space passed near an object closer to us like our sun the light would bend so that the apparent position would be shifted from the actual position as observed from the earth. It took an eclipse of the sun with a very bright object slightly behind it and a few years but conditions were finally right and Einstein's prediction was proven. It is the bending of light through a lens that makes a telescopes work. So light bent by a mass in space makes it act like a telescope. This means that, we can use massive objects in space to see images of the objects behind them. The image is somewhat distorted and sometimes multiple images of the same object are created but we can often see objects that we could never see with our normal telescopes. It's best when the massive object is about half way between us and the distance object. Some of the most interesting results come from when the massive object is a cluster of galaxies. But the other important thing is what we learn about the lens. The angle that it bends the light tells us it's mass and every thing that isn't visible normal matter is dark matter. There are other little tricks to getting it right, so again, I'll leave that to the author.

This book takes you on a journey from the universe of Einstein to the universe as it is understood today and beyond to the edge of what is unknown and maybe unknowable. Evalyn Gates is the perfect person to take us on this journey. She is the assistant director of the Kavli Institute for Cosmological Physics and also a senior research associate at the University of Chicago. She is the former astronomy director of the Adler Planetarium and Astronomy Museum. She makes a complex subject accessible to the average reader. She doesn't assume that you have the prior knowledge and background to understand the subject matter. She uses the first three chapters to make sure you have the background to understand the rest of the book. If you want to get the latest knowledge for understanding what is known about our universe, this book, with it's accessible explanations and many helpful illustrations is the one to get. The author tells you to start with the beautiful color pictures of actual telescope images located in the middle of the book, just for their beauty. Then go back to them as they illustrate the topics in the book.

All my life I've been a seeker after knowledge. I've worked in science, music, the financial field and spent many years as a member of a public speaking organization. I am an avid reader of non fiction books on many different topics. I have a knowledge web site. It's purpose is to share knowledge. Right now it has an extensive music section, some pages on how money works, and a book review section. I like to keep up with scientific knowledge and try to read all the latest books.
