Buying Cheap Telescope&Must Knowing
Source:Ruilong Time:2011-4-7People in the purchase of the telescope, the common price list on its several Arab figures, then these figures show what technology parameters The following interviews give an example of it. For example labeled 10 × 50mm5 °, that means the magnification is 10 times the diameter of 50 mm objective lens, field of view of 5 degrees (ie, width of view in 1000 was 87.4 meters). Some may think that the number of the better technical parameters, it is not. Width is inversely proportional to the magnification and field of vision, namely, the greater the magnification, the smaller the width of vision, which is not conducive to the search. Objective lens diameter and the amount of light the more the ability to differentiate in low light, the stronger, but this will inevitably lead to increasing the size of the telescope is not conducive to carry. The say this, perhaps you are feeling at a loss, but as long as each other, the same can buy a desired telescope.
The whole point of a cheap Orion telescope is to make a sale to the customers. They can lure in the amateur astronomers and make them interested in the star-gazing hobby. It is also important to note that there are experienced astronomers who still go for a cheap Orion telescope because they get to save money. They know that as long as they get the features that they are looking for in a telescope, they're set. That's what's important anyway.Another thing that makes Orion telescopes different from the other brands of telescopes is that they group their telescopes in levels. These are "beginner", "intermediate", and "advanced." The level of the cheap Orion telescope determines which is the right model for the astronomer.With the levels, he can also determine whether the telescope is what he needs in order to view what he want to see.
There are different mounts to choose from as well. The mounts allow the astronomer to see the scenery better. It may be cheaper, but they still keep up with their reputation of high performance. Orion has two element apochromatic refractors.These are manufactured in China. The user can adjust the low dispertion of the objective lenses. In doing so, what he is seeing is clearer and he can appreciate it better.A cheap Orion telescope for terrestrial and astronomical observation are currently sold in the market. The microscopes and the monocular spotting perfumed by the telescope is the best method to use when bird watching.The resolution of this telescope can be adjusted to reach the stars or just right across the field.
