Power isn’t Everything with Astronomical Telescopes
In the case of so many products, consumers can be driven to think power is everything when they are choosing between different options. However, in the case of astronomical telescopes, this is not so.
Some individuals may be surprised to hear that a telescope’s aperture has no bearing on its magnification, but rather it is the focal length – which is the distance from the lens or mirror to a point at which it forms an image of the distant object.
Generally speaking, low powers are used to look at faint subjects such as galaxies and nebulae because if they are enlarged too much, they will lose some of their clarity.
So when seeking an astronomical telescope, simply going for the most powerful possible may defeat the point and you could be left with inferior results, depending on what your goal is.
There are a plethora of such devices available and when searching through the options, you should have your specific requirements in mind.
This way, you will be able to avoid homing in on a product that is inappropriate. By approaching the task of buying in this way, you are likely to be able to avoid possible disappointment.
There are three main categories of such telescopes used by amateur astronomers. Roughly, they fall into refractors, reflectors and catadiopiric.
Whichever of these you need, make sure you take into account all the necessary factors – rather than simply power – when short-listing your favourites and eventually deciding on one that you believe is right for you.
