A Telescope Guide and Review
Astronauts make various common mistakes when they decide to buy a telescope and more so the beginners. They just decide they want to buy a telescope then rush to a certain mall, enter any electronic store and buy a telescope without considering some factors. A packaging of a telescope may look appealing by the look because of the images drawn on the package like Jupiter or Saturn but when you start using the telescope it might not meet the promises because of poor design and cheap optics. A telescope that is of a good quality will meet all your desires and expectations. When buying a telescope for the first time or just a replacement for your telescope always make sure you consider some factors Below are some of the factors you should consider when buying a telescope
The aperture is always the first thing to look for in a telescope. The aperture is the size of the lens or mirror that focuses light from a very distant object. The image quality will not be good if you buy a telescope whose aperture size is not good. The right size of the aperture will make you see objects clearly because using an aperture is just like enlarging the size of your pupil in the eye and seeing objects or images in a clear way. If you want to have a good view of images then you should consider on buying a quality aperture and not the magnification. Sometimes telescopes are just advertised by the use of a magnification but you should have the knowledge to know that a large magnification on a too small telescope will give a blurry image.
Telescopes use lenses to refract light and mirrors to reflect light. Telescopes of a smaller size use lenses while the telescopes of larger sizes use mirrors and it is the best option for you. For the ones who want to view terrestrial or celestial images, using telescopes with refracting lenses is the best way to go. Viewing sailing boats birds and landscapes should use telescopes with reflecting mirrors. Viewing the heavens is also good when you use reflecting mirrors. When using reflecting mirrors, you will not be affected by the chromatic aberration where various colours are not brought to the same sharp focus.If you want a nice viewing always put your telescope facing the right direction At night the earth is always rotating on its own axis so you might notice objects moving.
When buying a telescope the streets camera shops and any store are not advisable places for the buying. The best places to buy a telescope are shops with the best and experienced astronomy experts. Specialists in telescope manufacturing produce better telescopes than any other manufacturers. Buy your telescope in a place where you will be allowed to first try it before fully buying.
