There are several factors you will need to think about when you buy that first telescope. The salesperson will no doubt cover for you all the advantages of having the biggest aperture and all the accessories you will ever need. However, there are a few considerations the salesperson might miss that will be just as important to you.
Portability is important for most people for their telescopes. This is because there are many objects in the sky that can be seen better from different locations. You may need to get out of the city and away from the light pollution that it there to see some things. Some solar or lunar eclipses are best seen from remote locations.
You want to be able to take your telescope with you. Therefore, it should be easy to take apart and put back together again. In fact, you will probably have to be able to put it together in the dark. It should not be difficult to carry, and if it does not fit into your car, you will not be able to transport it.

When most people think of telescopes, they think of the tube-shaped refractor or reflector telescopes used by amateur astronomer. Others think big and remember that the great Hubble Telescope is out there in space, instead. In fact, there are these and many other different types of telescopes.
The visual, or optical, telescopes have been around the longest. The first refracting telescope was constructed in about 1570. Galileo did some work on it and made it better. He improved it so much in fact that he ended up with a 20-power telescope. With it, he could see some of the moons of Jupiter. Isaac Newton invented the first reflecting telescope about one hundred years after the first telescope, in 1671.
In the 1930s, Karl Jansky was interested in the short-wave radio interference that people doing Trans-Atlantic communications noticed. After much study, he ended up building a rotating radio telescope. With it he discovered how many phenomenons on earth created the static.
However, he also pulled in radio noise from the Milky Way. Radio telescopes need to be very large if they are going to override the earthly radio […]

If you are looking to the stars and want to get a better look; of course you know that your next investment, whether as a novice stargazer or an avid astronomer, is a telescope. Unfortunately, as is true of most technological investments; painstaking research must be done to compare product specs, costs, and overall features to find the best telescope for your particular purposes. Not to fear: here is all you need to know on the latter aspects, to aid in your beginner telescope purchase.
First and foremost, there are three basic types of telescopes: reflector, refractor, and combo catadioptric.
0 The reflecting telescope (or Newtonian) basically uses a concave design and mirror lens to reflect light off an object in the distance, to perceive it more closely. These types offer great light-gathering technologies, are typically stationary, and are the least expensive of the three. They are the best beginner telescopes for those interested in casually exploring the night sky at a value price.
0 The refractor telescope works by using a number of lenses to refract or bend the light that is being transmitted by a distant object, to gain a more focused magnification from the eyepiece. Refracting telescopes are comparatively much […]
