Finding a good Celestron telescope can be tough these days, with so many things to compare between models, such as focal length, aperture and mounts, and so many Celestron telescope reviews to read. If these terms confuse you, or you simply don’t have the time to do a lot of reading, then you should be glad to learn that we have compiled a short guide which should help you find the best telescope for your needs and budget without allocating dozens of hours to do your own research.
Apertures and image quality
One of the main technical details you often hear about when looking for a telescope is the aperture. This can be described as the diameter of the main mirror or lens which captures light bounced by bright objects. The biggest the aperture, the more light can the telescope capture, resulting in brighter images. But brightness isn’t the only benefit to a large aperture, as its size is also directly related to the level of details. A telescope with a larger aperture will be able to resolve more details, thus have a higher resolution with better and sharper details.
But depending on what you want to study as well as your budget, you don’t need to spend huge amounts of money only to get a large aperture telescope. The quality of components also contributes to resolution power, as finely-ground glass mirrors will bring out more detail while being more expensive than lower-quality glass components.
While this may surprise you, the aperture of any given telescope does not affect magnification. What does affect magnification is the focal length of the telescope or lens and the eyepieces you use.
The focal length is the distance between the main lens through which light enters the telescope and the focal plane where the image is formed. This distance is usually measured in millimeters. So a 700 telescope has a focal length of 700 millimeters or 28 inches. Eyepieces have their own focal lengths. The magnification or power of any given telescope is obtained by dividing the focal length of the lens by that of the eyepiece. A 500-millimeter telescope with a 25 mm eyepiece will have a standard magnification of 20.
You can always increase magnification by adding an eyepiece with a shorter focal length. However, you should try not to exceed the maximum useful magnification, which is usually double the aperture number in millimeters or 50 times higher than its value in inches.
Stability is important
With telescopes, it doesn’t matter how large the aperture is or how much magnification you have if you don’t have a stable mount. Without a solid base to rest the telescope on, the image will not only shake in all directions, but it would also be challenging to hold a specific object into the field of view or focus properly.
Fortunately, many telescope models come with great mounts which allow you to easily track celestial objects and to lock on them while also taking into account Earth’s movement.
