A Telescope Guide and Review
There is a very common mistake that every astronomer makes especially the beginners. They decide to buy a telescope then enter a random electronic store and buy a telescope without considering some key points. 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. If your aperture size is not good enough then the image quality might not be good as you want. 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. The determinant of a good telescope which will give you quality images is not the magnification but the aperture. 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.
Light reflection in a telescope is done by the mirror while the refraction is done by a lense. Telescopes of a smaller size use lenses while the telescopes of larger sizes use mirrors and it is the best option for you. If you want to view terrestrial or celestial images you should use refracting lenses. Viewing sailing boats birds and landscapes should use telescopes with reflecting mirrors. If you want a nice view of the heavens then you should always buy telescope with reflecting mirrors. If you use reflecting mirrors, chromatic aberration where various colours are not brought to the sharp focus of the same angle.There is always certain positions you should place your telescope so that you can have a nice viewing. Because of the earth moving around its own axis at night, you might notice the 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. If you are buying a telescope, request the seller to allow you test the telescope first.
