When Galileo made his telescope, he was far from the expert he became later. He was just a layman, who found the sky and its stars fascinating and wanted a device that would take him closer to the object of his fascination. It was this desire that led him o devise the first ever telescope that changed the face of history in more ways than we can imagine.

 

In today’s age, a person is able to buy a telescope, readymade, from the market. But for one who is not experienced, constructing a telescope is akin to an adventure. Although the procedure is complex and technical, and quite long, it is quite possible to make a telescope for oneself, by oneself. For the amateur who holds a keen interest in the telescope and the way it works, constructing it by oneself can be quite adventurous and fulfilling.

 

The construction itself is not very difficult, and it is made easier if one can enlist the assistance of another person who has himself constructed telescopes earlier. Even someone who is an amateur astronomer would make a good mentor, if it’s no possible to find one experience in telescope construction. Astronomy clubs generally have at least one member who has prior experience of building telescopes, and such people are quite accommodating towards amateurs.

 

For an amateur, telescope construction can be a cumbersome task. Patience and calm are advisable for a first-timer. The greatest inventions of all time came from blind experiments and unexpected results. When starting out, it is always best to have some references and manuals handy, as they can explain the technical aspects in the clearest ways. A local library is a good source for material to an amateur just starting out in telescope building.

 

The basic elements of a telescope are the mirror, two lenses, the housing for the whole structure, and materials that will be used for polishing the mirror. These parts can all be bought at local stores or even online. The mirror can be ground at home as well, but is a tiresome process.

 

The construction of a telescope is a long and drawn out process. Careful planning is required to ensure that there is minimal cleaning up left after all the work is completed. Is advisable to lay out newspapers to ensure clean work as well as to ensure correct placement of all the equipment. Maintain a logbook if possible to keep track of the task completed and the duration of each task. In later stages, the logbook is a good record to refer to understand the tasks completed and how long each task required. Also, it helps one to remember what work has been completed and what remains.

 

Once the construction is complete, it is quite natural for the amateur to be pleased with himself for the work he has accomplished. It is however, easier to buy a telescope kit from the market instead of purchasing individual component and constructing the whole structure. Assembling a telescope from a kit is easier, takes less time and is a better financial option. Such telescope kits are intended for the amateurs, and not directed at the professionals.

Telescope is an exciting physics equipment. Buying a telescope is a daunting task for a newcomer. It all depends on your astronomy goals and careers. There is no perfect one which suits all observers in all conditions. You have to look for the features you want in your telescope and select the best one’s according to your requirement.

Selecting the proper type

The refractor type telescopes best suit for watching moon and major planets. Refractor telescopes are long & thin, and known for their sharp, detailed and contrasty images. They collect light through multi-element lenses. If you are just a starter then a small, quality achromatic refractor of 60 to 90 mm aperture would be a good one. The best thing about a refractor telescope is that they are inexpensive, portable and almost maintenance free. A refractor telescope is also useful when you will be mostly observing from city or the surrounding areas where the night skies are lightly polluted.

Reflector telescopes are also known as Newtonian telescopes. They are good for planetary as well as deep-sky viewing. However Newtonian telescopes are more fragile and need more maintenance than others. These telescopes collect light with a curved, concave mirror and with the help of their large apertures, they show fine, highly-resolved images. The reflector scopes are not suitable for terrestrial viewing because they produce an upside-down image.

Catadioptrics use both lenses and mirrors to collect and focus the incoming light. They are also called compound telescopes. Catadioptrics scopes are considered the most versatile telescopes and gives great all-around performance. They use a large aperture in very compact tubes. They show magnificent images of the moon, planets and faint deep-sky objects, when viewed in dark skies away from urban areas. These scopes are best suited for astrophotography. Compared to other two, these scopes have a wide range of accessories available. They can be entirely computer controlled.

Factors affecting the performance of a telescope

Aperture: Telescopes collect light from distant objects and focus it to produce images. The light collecting capacity of a telescope is the most important feature. It is the aperture of scope (diameter of mirror or lens) that is responsible for gathering light. Larger the aperture, the more light gathered, the more you’ll see.

Telescope Mounts: There are three basic mounts for telescopes altazimuth, Dobsonian, or equatorial. Altazimuth is the simplest type of mount, providing up-down, left-right motions. It is mainly recommended for terrestrial viewing and casual stargazing. The Dobsonian mount was basically designed for easy maneuvering of large reflectors of more than six inches. It is a boxy altaz-type mount sitting close to the ground. Equatorial mounts are designed for the purpose of astronomical viewing. These mounts are more expensive and complicated than the altazimuth mounts. With the help of these type of mounts users can track or follow the motion of celestial objects through the sky with a single manual hand control.

Magnification: Magnification should never top the priority for buying a telescope. The quality if image degrades with magnification. Practically 300X is maximum magnification for good quality images. Telescope’s magnification is also known as its power and it is adjusted by changing eyepieces. Ideally there should have been three eyepieces for the magnification of a scope: one low, one medium and one high. Lower powers of 30 – 50X are recommended for observing galaxies, star clusters and nebulae as they are spread over a wide area of sky. For observing the rings of Saturn, Jupiter, studying craters and valleys of the Moon’s surface medium power of 80 – 100X are advised. Higher powers of 150 – 200X allow the astronomers to observe mountain peaks and fine lunar detail, the surface features of Mars.

Are you interested in astronomy? Wouldn’t it be great, to really see, what all those shinning points of light are, in the night sky? Well, you can with a telescope, but how to buy a telescope? What do you need to get started in astronomy, and wouldn’t it be great to have it all in an easy telescope buying guide, such as this article?

Well, you have it. Here is the article that can help you get into astronomy. First it is important to consider a few points, when wondering how to buy a telescope. The first and obvious step, is buying a telescope. However, there are some other parts, which go to make your hobby in astronomy, so much more fun.

You need 3 things to get the most out of astronomy, and 1 other item, which I recommend:

1. A telescope (this telescope buying guide, should help with that!)

2. A star atlas

3. A good practical book on astronomy and telescopes

* Optional

4. A notebook

Let us look into these necessary items to get the most out of astronomy. Remember, you can easily get into astronomy, by studying and learning the constellations. Some people in our human history, devoted there lives to constellations, some even to just 1 or 2!

* 1. How To Buy A Telescope?

Your first step before buying a telescope is to consider what you want it for. Remember, telescopes are scientific instruments. This is an investment, and generally more you pay, better telescope you get, which can literally last a life time.

If you have been wondering how to buy telescopes, you have come to the right place! Buying a telescope requires buying from either 1 of 3 places. From a specialized telescope shop, though these are not always easily found. The next is through mail order and the third, which is the easiest, is online.

There are 2 main types of telescope, one is reflector telescopes (catoptric), and refracting telescopes (dioptric). One has a big mirror, and the other is longer, and slimmer. They both pretty much do the same objectives. However, many people prefer the reflector for deep space viewing.

* 2 & 3 – A Good Star Atlas And Practical Astronomy And Telescopes Book

Getting the most out of the science of astronomy is not about buying the biggest telescope or the high price you paid. Instead it is about knowing what is where, and where to look.

Galileo’s telescope was so inferior to today’s telescopes readily available, that he said that Saturn has ears! However, he still invested a lifetime into the study of these objects.

The key to knowing where to look is with a good star atlas, and a practical astronomy book, designed for small telescope use. A book called – Turn Left At Orion, seems to be the most popular, and easy to follow.

* 4. A Notebook

Viewing Saturn, Jupiter, and the Moon, can be fun home scientific tasks, but what happens next? We get bored! The truth is, to get the most out of astronomy, is to treat it as a science. Even if you are the worst painter, you still can record a detailed picture of the Moon’s craters over days, and see the differences. This will go a long way in the future, and will allow you to look back, and see what many people will never see and all because you invested into the science of astronomy.
