If you are a beginner, buying a used telescope will offer you a great value of money compared to an expert in this field thus enabling you to get hold of high spec brands and top models. If you would like to purchase used telescopes there are various places to look for.

Local classified ads are an easy, accessible and local way of finding old astronomical telescopes. These people might be just a short distance from ones home and might even deliver to ones request. There are also telescope store that have great selections of old telescopes for sale. The best thing about these stores is that they usually have set standards hence it is possible to find one that works well.

Another place where pre-owned telescopes are accessible is online. It is possible to shop online for used telescopes due to the variety of stores who have websites where one can shop. When purchasing old telescopes it is good to take a good look at the astronomical device to ensure that the optic is in its right state. For reflector telescopes, one should check the mirror to ensure there is no breakage as it can affect the image. On the other hand, if it is a big telescope then small errors would not necessarily cause a big problem.

The other major point is checking whether the mount and the tripod is functioning well. You find that those are into astronomy consider the model of telescope they are purchasing. One of the best types of telescopes for beginners is Dobsonian. You find that most reflector telescopes can be operated easily and when you are buying a used telescope you can get a real bargain.

One of the major primary considerations for all of us when purchasing anything is the budget. However when you are buying a telescope you should consider its purpose first. If you live by the ocean or in the countryside and your interest is nature, you should opt for a lower spec brand compared to one whose interest is astronomy.

When browsing for used telescopes it is good to choose a second hand one from a reputable brand and not get carried away by other enticing models produced by unknown manufacturers. In this case, functionality is the main key. A telescope with whistles and bells is great but for those who can operate them. For a novice this will interfere and complicate things further.

Used telescopes produced by reputable brands are usually backed up by a good wealth of expertise and have been built up over centuries. Such manufacturers give it their best in producing top quality products. Their aim is to retain and attain loyal customers and their longevity restores confidence to the customers.

Used telescopes and telescope equipment is going to help individuals save cash. Are individuals interested in saving cash? Then check out what we have.

new to me telescope made by meade very well made scope i really am enjoying this telescope and iam sure i will for many years to come

The shapes, the sizes and what it is being used for are ways that one can categorize these apparatus. The usage that is intended for an apparatus is the first thing that comes to mind when you want purchase such a thing. The ones that is mainly used for planetary viewing is the most popular but there are others for stuffs like bird-watching and other minor activities.

The eclipse of both the sun and the moon can be watched from this equipment with a good amount of clarity. Some uses it to watch the crescent-like movement of the shadow that the earth cast on the moon that is popularly called the partial lunar eclipse. It made the work of the scientist in history easier.

A total eclipse can be seen in every two or three years and is a complete covering of the surface of the moon by the shadow casted by earth. The whole incident does not take that long before the moon goes back to how it used to be. Kids can have a lot of fun with it.

This equipment needs to be put in a place where it will not be moved or disturbed preferably on a fault floor in a room upstairs. And because it needs to look out into the sky, the place has to be by the window. This is to be sure that nothing obstructs the viewing process.

It is good for one to get used to owning something like this one so one should just explore the parts and what each one seem like. It makes it much easier when the time is right for the proper usage. The first step might even be to try out each eyepiece to see how they fit and what they view.

The lens cap has to be removed before you go further because if you do not remove it all you see is darkness. And remember to always put the solar filter when you want to see the sun and the moon filter when you are viewing a moon. They can damage your eyes if you are not careful.

The other thing is to shake the pivot joints lose in a way that it will be steady then face the product in the direction you want to view. The spotting scope will then locate the object you want to watch and bring it into the cross-hairs which then centers it. When it is in the center, tighten the joints to keep it solitary.

Lastly, to do the proper sighting, bend and look into the eyepiece and adjust the focus knob till the image is in your focal point. What you see then is from space which makes the advantages of owning a portable telescope a good experience to have as a kid.

Kids, get the low down on the advantages of owning a Portable Telescope now in our article on how and where to find affordable Portable Telescopes online

Binoculars are essentially two identical telescopes positioned side-by-side aligned to view toward the same object. Binoculars equipped with night vision (NV) technology take the real image and digitize it into an electronic format and, in so doing, illuminates it. The potential benefits provided by this technology are enormous, virtually endless. For example, it allows scientists to study nocturnal animals at work or play in their natural habitats. For hobby birdwatchers, NV binoculars open up an entirely new dimension to their pastime.

Similar to microscopes and other specialized optical instruments, NV binoculars have several lenses. The objective lens is positioned closest to the object under scrutiny or, in other words, the lens furthest away from the eyes of the viewer. This lens collects light from the viewed object. The magnification of that image is controlled by moving it closer or further from the objective lens.

Like all binoculars, NV sets will carry a magnification rating such as 8×40. The rating is typically stamped on the casing. It indicates that the binocular is capable of magnifying any object to eight times its actual size and that the lens size is 30mm. When magnification is increased in binoculars, the brightness as well as the field of view decreases.

When buying NV binoculars, it is important to check out details related to the lens coating. The coating on lenses is a technological marvel unto itself. The lens surface consists of many fine layers of chemical coating. The details of this coating are important to the overall effectiveness of the lens and its working longevity.

Given that NV binoculars represent a significant investment, it is important to use special cleaning cloths. Modern microfiber lens cloths are made purpose-made from tiny polyester or polyamide fibers that are a thousand times or more thinner than human hair. They allow binocular lenses to be cleaned with minimal scratching.

NV binoculars can be expensive. Choosing a pair warrants research so that the set chosen will match the needs of a user. One important consideration is that even the best binoculars are useless unless they can be carried, handled and used where they are needed.

For sailors, binoculars should be light enough to be easily hung around the neck and handled securely in wet conditions. They should be able to withstand complete immersion in water. They should also be made of sturdy, durable materials consistent with the large temperature ranges, high salinity and generally tough and testing working conditions that prevail on vessels at sea.

In conclusion, people these days no longer need to ask themselves night vision scopes what are the benefits. The pricing of that equipment is within reach of most enthusiasts that require magnified vision at night, whatever their field of interest.

Sneak a peek at our article on the benefits of Night Vision Scope. You can also get complete details on how and where to find affordable Night Vision Binoculars on the Internet.

The Telescope turns 400 years old this year and in four century period astronomers and telescope makers have been continually making larger and larger telescopes in order to peer deeper and deeper into the mysteries of the universe. There are currently quite a few enormous instruments in use and there are several next generation telescopes being developed that will dwarf anything currently in use. This article takes a look at some of these magnificent monsters of astronomy.

The largest Refractor telescope

Refractor telescopes are renowned for their absolute sharpness of image because they are composed of very large lenses of compounds of glass which gives them crystal clear images. But they are extraordinarily difficult to make in a large size. Their own weight distorts their shape and makes them unusable above a certain size.

The largest refractor in the world is the Yerkes telescope which has a primary lens that is 40 inches in diameter. It was completed in 1897 and was built by the famous master optician Alvan Clark. It represents the pinnacle of refractor telescope making and no larger one has since been built in the hundred years since. Reflectors are much more feasible for larger sizes and there are many of this type that are extraordinarily large. It is with reflectors that we achieve very large instruments.

Reflector Telescopes

Reflector telescopes come in two different types. The first type is the single mirror type where a single piece of glass is cast and polished to make the primary mirror. The second type is the segmented mirror where a series of hexagonal mirrors are assembled together into a single large mirror. This type of mirror looks much like the honeycomb from a beehive and this new technology is allowing telescope makers to make instruments larger than ever imagined.

The largest single piece of glass telescope in the world is the Large Binocular Telescope (LBT) in Arizona. It is a telescope composed of two separate mirrors that are side by side and work in tandem. The light from both of them are blended into one single image. Each mirror is 8.4 meters (330 inches) in width and when used together they create the equivalent of a mirror that is 11.8 meters (464 inches) across which is currently the largest light collecting size on Earth. It is located in Mount Graham International Observatory in Arizona.

Segmented mirrors pose technology challenges that have been overcome in the past decade and now these multiple mirror scopes are being built in extremely large sizes that cannot be rivaled by single piece mirrors. Of the segmented telescopes where a series of honeycomb shapes are assembled together into a single telescope there are three different observatories with these largest of mirrors.

The South African Large Telescope (SALT) is the largest primary mirror scope in the world and it has a segmented mirror that is 11 meters (433 inches) across.

The Gran Telescopio Canarias or GTC is located on the island of LaPalma Spain and it has a segmented primary mirror that is 10.4 meters in diameter (409 inches) which makes it the single largest mirror in the world.

The Keck Telescopes are a pair of telescopes located at the Keck Observatory in Hawaii. Each mirror is ten meters (400 inches) in diameter.

Bigger Telescopes to come

There are even larger telescopes currently in the proposal, development, or construction stage. Technology improvements over the past decade have made a new scale of telescope possible and this new scale is referred to as ELT or Extremely Large Telescopes and it is the next generation to come. ELT’s are telescopes that are more than twenty meters in diameter which is double the size of existing telescopes. And this doubling of size gives significantly more than double the light gathering power. Most of these scopes will be of the segmented mirror type but one notable exception is the Giant Magellan telescope which will be composed of seven spherical mirrors constructed together so they act as a single mirror. This project is scheduled for completion in 2016. It will be located in Las Companas Observatory, Chile.

The Thirty Meter Telescope (TMT), which is currently in development, will be thirty meters across and composed of segmented mirrors. It is expected to be a telescope of unmatched performance and is predicted to be able to image planets circling other stars. The current time line for this project is for it to be completed somewhere around 2017 – 2018.

What about the Famous Hubble Telescope?

The primary mirror in the Hubble is 2.4 meters across (94.5 inches) which makes it rather small compared to some of the giants listed in this article. So then why is it the most spectacular telescope ever created? The big advantage the Hubble has over all the other telescopes is that it doesn’t have to peer through the soup of Earth’s atmosphere. And this advantage is staggering. That is why the Hubble has brought us some of the most extraordinary images ever recorded.

What comes after the Hubble?

NASA is currently working on its next generation space telescope. It is called the James Webb Space Telescope (JWST). The primary mirror will be 6.5 meters (21.3 feet) in diameter. Launch is planned for 2013.

Since the invention of the first telescope 400 years ago man has been building ever larger telescopes. The telescopes to come will bring us images of planets around other stars and who knows, they may bring us images of the very birth of the universe we live in.

Space telescopes are amazing instruments. Looking up to the sky on many occasions deep down you want to soon see more. A shining glimmer of light from a star is not enough, we want to see the beauty the universe contains. Your first astronomy telescope can be a blessing or a curse! Read my latest article on finding the right first astronomy telescope for your home.

There is a couple of things to clarify before we take a deeper look at what kind of planet telescope will be right for your needs.

1. When you look through a planet telescope it will be in shades of black and white.

2. The pictures on the planet telescopes box is taken by a professional astro-photographer.

Think of the planet telescope box for your first astronomy telescope as the pictures from fast food restaurants. The picture looks amazing in the picture, but the result is less than imagined. This can deter people thinking that planet telescopes are not what they make out and that they should decide not to buy a first astronomy telescope. This is not the case, after all we still love the fast food. Your first astronomy telescope will still bring you amazing sights which are breathtaking.

One thing to keep in mind is the price and quality factor. In the last part I gave you an example of a fast food chain and the pictures. Now if you purchase your first astronomy telescope for $100 or less, than realize that the quality of your first astronomy telescope will not satisfy your desire to see the universe.

Those first astronomy telescopes selling for less than $100 are great for looking at the moon, but will prove no use for any deep space viewing. The key to having the best first astronomy telescope is to make sure your first astronomy telescope has a strong mount, otherwise the image will shake everywhere, and you will not see much.

The best option is to go for a $200+ planet telescope for your first astronomy telescope. The price determines quality with planet telescopes whether it is your first time planet telescope or you are a seasoned planet telescope user. And the most important parts that need quality is the planet telescope mount, planet telescope lens, and planet telescope mirror.

The main items to look at when buying a planet telescope are the two numbers that will tell you how well it is expected to work. For a great first astronomy telescope, a listing of 20X50 is about average. This means the magnification will equal 20 times what you see with your eyes and the 50 is the width of the length, which is what determines how much light is gathered. The more light the better the image will be visible in the dark and for astronomy, all star gazing is typically done after dark.

A lot of the cheap planet telescopes try to sell you on fancy gadgets. They look good to have on your new first astronomy telescope, but the truth is that these kind of features will be of no use. Consider on a $100 first astronomy telescope that comes with loads of fancy gadgets, most of the money is going on those features. All you need to get started in astronomy with a first astronomy telescope is to make sure more of your money goes on the planet telescope mirror, planet telescope mount, and planet telescope lenses.

One last thing to consider before you buy your first astronomy telescope make sure you take into account the space your first astronomy telescope will need. It needs space to move around ;>. Good luck with buying your first astronomy telescope.

If you have ever tried looking through a telescope without a telescope mount to steady your equipment, you understand the difficulty of focusing on a set object in the night skies. Compound that problem with a heavenly body that is actually moving across the sky and you realize that it is almost impossible to track this object. There is no doubt, stability of your telescope is key to enjoyable stargazing.

Purpose of a Telescope Mount

A telescope mount provides a stable platform for your telescope, whether it is a refracting telescope, reflecting telescope, Dobsonian telescope, or catadiotric telescope. A telescope mount will ensure that your viewing of a celestial body is not interrupted by unexpected movement. It also determines how you will position your body relative to the telescope to view the night’s sky, determining how comfortable you will be over any extended period of stargazing.

Types of Telescope Mounts

Altazimuth telescope mounts are generally used on a Dobsonian type telescope. These telescopes look like a large canister and are mounted on a chassis that provides limited mounting capabilities. With this type of mount, the telescope can be adjusted in up and down or left and right positions. This range of movement in a telescope mount is generally fine for the beginner and intermediate astronomer.

Equatorial mounts are more advanced and allow for greater movement to coincide with the movement of planet Earth. As good as this sounds, there is a level of skill required by the user. The user will need to understand the planet movement and be required to make minor adjustments to the telescope mount. This type of mount is usually reserved for higher quality telescopes, so it is really geared for the intermediate to advanced astronomer. However, with a little experience and practice, the mount could be used by most stargazers.

In this hi-tech era, computers have become an integral part of astronomy and are used to move and track heavenly bodies. Well, an advanced telescope mount, though expensive, is available that provides this kind of computer tracking and superior viewing options. This mount even facilitates the viewing through the computer monitor as well as the eyepiece, with a few clicks of your mouse moving the mount into position.

Choosing the Right Mount

In choosing the right mount, you must first determine what the intended use of the telescope is. Other considerations are the skill level and specific needs of the operator. Determining the type of terrain the mount will be used on will dictate the stability requirements. And, of course, your astronomy budget will play a major role in what type of telescope mount you will purchase.

Choose a mount that will allow for a comfortable body position for times of extended viewing. Nothing can ruin a stargazing experience faster than being required to contort your body in unnatural positions to get a satisfactory view of your desired object.

So, to choose the right telescope mount, take the time and effort to research the different brands of telescope mounts and the various quality levels available. Then, and only then, choose the one that best suits your needs and falls within your budget limits. It can make the difference between a comfortable, enjoyable stargazing experience and a cramped, short-lived outing.

Benefits Of Buying A Used Telescope

There are a few benefits of buying used astronomical telescopes. The biggest point is cost saving. I have seen many occasions where a used telescope is being offered for sale. The telescope is a 10″ Meade reflecting telescope, and it sounds amazing, and the telescope is great, but is it? This we will answer in a bit, but for now, realize the huge savings.

A used telescope can be purchased for the fraction of purchasing a telescope that is new. This alone can be great, especially if you are on a budget. The question is how do you find these used astronomical telescopes for sale?

Where To Find Used Telescope For Sale

In fact there are several places to find used telescopes. The first place to look is local classified ads. These can be a great way to find used astronomical telescopes, because it is easy access, and local.

Most of the time, these people will be a short distance from you, and may even deliver. Though this is one way to find used astronomical telescopes, there are other ways to find used telescope for sale.

Some telescope stores have a selection of used telescopes for sale. And the good news is that the store usually will have a set of standards, so if you buy this way, you can find a telescope that at least works.

Online you can find used telescopes also. You may find that with the price savings online, it may just be better to buy a new telescope. In either case, it is a good idea to find out prices of new, so you can evaluate if it is worth buying it.

How To Get A Good Deal When Buying Used Telescopes

Make sure you take a look at the used astronomical telescope. You want to make sure the optics is in order. In reflector telescopes, check the mirror and make sure that there is no damage, as that can affect the image. However, if the telescope is a big telescope like a 10″, then small errors won’t cause a big problem. The problem comes with refractors and damage to the optics.

In either case, the main point is to make sure the optics is in good order. The next point is to look at the tripod & mount. You want to make sure that is working. And next to haggle the price, to get the best deal!

If your youngster is showing interest in stargazing and astronomy, a kids telescope can get them started with their new hobby without a large investment. Realize that a kids telescope is not a toy, but a fully functioning beginner telescope without all the advanced features.

Giving your youngster a kids telescope will let them know that you support their interest in astronomy and see it as a worthwhile endeavor. A real telescope, even without all the features, can give your child or grandchild a head start in learning about the universe and star systems.

Investing in a Kids Telescope

While you can purchase a child telescope for under $25, these are really more of a toy than a functioning astronomy telescope. A real basic beginner telescope can be purchased for around $100 and can provide the young astronomer with a gateway to the heavens. If you wish to invest a little more, a good starter telescope with some of the more advanced features, will cost anywhere from $200 to $300. This will provide your youngster with a quality piece of stargazing equipment.

As the child’s interest grows, an investment in a more sophisticated telescope model might be appropriate. For instance, many young astronomers enjoy having the capability to photograph certain star formations or passing comets.

Tips for Buying the Right Child Telescope

Many astronomers and educators recommend a telescope with a longer focal length and separate viewer. This allows the child to find objects much easier and reduces the frustration that can result for the novice astronomer.

There are many cheaper models that offer a focal length of only 30mm or 50mm and will provide a more generalized view of the night sky. However, if you want a telescope that will provide a more detailed picture of the planets, moon and constellations, a 70mm or higher focal length is strongly recommended.

Kids telescopes are available from a number of top-rate optics companies like Meade, Celestron, Bushnell, Orion and many others. Even the Discovery Channel offers an affordable 70mm lens kids telescope with easy set-up and easy-to-use features.

Meade provides some of the best telescopes on the market today and caters to the amateur astronomer – from beginner to expert levels. For example, a 1000mm focal length telescope with photographic capabilities can be purchased for about $150. This is an excellent choice for the new astronomer because it provides a very good view of the heavens and shows details of the planets and moon that are generally not found with a telescope in this price range. An added bonus is that a 35mm camera can be attached to this telescope that allows your child to preserve those special night sky views on film.

How to Use a Kids Telescope

Reading the instructions for your child’s new telescope can’t be stressed enough. Even the basic kids’ telescopes can be confusing to use the first few times. It is advisable for the parent to read through the instruction manual and help the child astronomer learn the basics of the telescope’s operating features.

A great way to enhance your child’s interest in astronomy is to view the night skies together. There is no better way to bond with your child than by enjoying the same hobbies and actively pursuing them together.

A kids telescope can open up a whole new exciting world to your youngster. It can broaden their understanding of the universe and allow them to be a part of the cosmos beyond just this planet. Why not invest in your child by getting them a kids telescope for fun, education, and a true bonding experience.

Are you thinking of buying a telescope? Perhaps you are wondering – what are the differences between refracting telescopes and reflecting telescopes, and which are better refracting telescopes or reflecting telescopes. As you read this article, you will discover more about which is the best telescope to purchase.

There are many different telescopes for sale. These different telescopes, however, fall into mainly 2 categories. The first is refracting telescopes, which is the one that reminds us most of Galileo’s telescope. The other is reflecting telescopes, which is commonly attributed with Isaac Newton.

Both refracting telescopes and reflecting telescopes have benefits, advantages and disadvantages. The key element here is that your needs are the main focus, and as you read this article, you will discover which type of telescope is best for your needs in backyard astronomy.

- Information About Refracting Telescopes

The design of the refracting telescope is also the type you find on binoculars, though in pairs! How a refracting telescope works, is that there is a lens at the front of the optical tube assembly.

Light enters the optical tube assembly, and goes right to the lenses at the back of the telescope. And finally meets the eye, where an image of Saturn, perhaps can be seen.

A refracting telescope is good, in that it is enclosed. The simple design, allows it to be maintenance free, for a number of years. The simple design also makes it easy to use, which is great as a telescope for children.

- Information About Reflecting Telescopes

How reflecting telescopes work, is that light enters the optical tube assembly, and goes straight to the back of the telescope, where it meets a big mirror. This mirror then reflects the light back up the tube.

Now, the light meets a secondary mirror, which is near to the top of the telescope. As the light bounces, it enters the lenses, and finally meets the eye.

Reflector telescopes are great in that they offer good price verses performance ratio. Reflecting telescopes can be much larger than refracting telescopes.

- Refracting Telescopes Compared With Reflecting Telescopes

Realize however, that the refracting telescopes are not cheap. Compared with reflecting telescopes they can be more expensive for similar performance.

For viewing the planets, buying a refracting telescope may be the best way to go, however, if you desire to see more of the heavens, there is nothing that compares, as with a reflecting telescopes. Though you may be able to get similar performance with refracting telescopes, you would need to invest a much bigger investment, which brings back the question – couldn’t the investment in a reflecting telescope be much better?
