Have you been wondering how to build a telescope? Building a telescope is a fulfilling thing to do. Not only can you take great pleasure in building a telescope, but you also get the added advantage of being able to view the heavens with your own homemade telescope. Discover more in this article on how to build a telescope.
Building a telescope is not the easiest thing to do. Luckily you don’t have to build everything. In fact, you can decide how much time and effort you want to invest, when you build a telescope.
If we look at how to build a telescope, the easiest way to go about building a telescope for backyard astronomy, is to build a reflecting telescope. This kind of telescope will be much easier, than trying to build a refracting telescope, which will likely need a lot of expensive equipment, which may not be accessible easily.
If we look at how to build a telescope, which is of the reflecting type, you will find that it comes with a few parts. You have the tripod, the mount, the telescope tube (that houses the telescope optics), the mirror, and the secondary mirrors.
Now, if you build a telescope, you […]

Refracting telescopes are the type of telescope we think about, when we use the word - telescope. There are many benefits to buying a refracting telescope. As you read this article, you will discover more about these benefits, and will be able to make a decision on whether to buy refracting or go for reflecting telescopes.
Refracting telescopes operate with lenses. This is the Galileo telescope, and works with light entering an objective lens, traveling through the telescopes tube, and meeting your eye through the optical lenses.
There is something to note about refracting telescopes, and that is that there is a limit with how big a telescope you can buy. Over 150mm objective lens sizes, the price becomes much more expensive than a reflecting telescope.
So, if you want to go for a larger sized telescope, then you may find price verses performance is better with reflecting telescopes. However, there are some benefits of refracting telescopes, which make them much better than reflecting telescopes.
A refracting telescope is all enclosed. And here is where many benefits can be found, over reflecting telescopes. Being closed to the elements, you will find that refractors are much more reliable and maintenance free.
With reflectors, you have to […]

It is actually quite easy to make a timeline with regards to the invention of the telescope as well as how it has evolved over the years. Much has been written about the telescope and good records have been kept with regards to new technologies and inventions. Basically, the telescope timeline looks something like this:
1609 - Galileo first invented the telescope. Though it was crude, it still did the trick and allowed him to look into space for the very first time other than with the naked eye. Galileo’s telescope was a reflecting one causing light to bounce off a mirror when looked at through a lens.
Mid-1600’s - Johannes Keplar came up with the idea of a refracting telescope that would widen the field of view as well as improve the quality of the image. He did this by changing the shape and the placement of the lenses, but doing this caused little circles of color that would surround bright objects - chromatic aberration.
Late 1600’s - As the century began to draw to a close, telescope makers were realizing that with a bigger lens, you could see much more. With a bigger lens, the […]
