How to choose the right telescope?

It is very difficult to choose a telescope because it is a product that can be experienced emotionally from the definition rather than the appearance.  But we at Apexel have been focusing on making telescopes and have a good understanding of telescopes, so here we sum up some experience, hoping to help you to choose the right telescope for you.  

How to choose the right telescope?  

(1) Purpose  

When choosing a telescope, the purpose should be put in the first place, buying a telescope always has specific needs, the telescope has high multiple and low multiple, center focus, and automatic focus, there are large size and small size, there are light and heavy points.  Is my personal opinion, can be observed from the portable outdoor, watch the game and the concert, land use and water use, use during the day or night use, more careful use of individual or rough use products, using the environment is bad or too hot too cold, fixed observation for a long time or short time observation, etc. To choose an appropriate own telescope.

(2) Easy to use  

Try choosing binoculars with eye patches that you can rotate and adjust to make viewing comfortable for your eyes.  This is especially important for eyeglass wearers, so you can look at objects without black circles around the image.  The eye patch will remove those black rings and you’ll get a clear image.  

(3) Multiple observation telescope  

The average telescope multiple is between 6 and 12 times, the most suitable multiple is 7 or 8 times, if there is a merchant said 1000 times, it must be false.  The telescope color that still has regular manufacturer production is black commonly, extremely individual just is military green.  

(4) Vision  

A mirror with a small field of vision looks uncomfortable.  Vision in 1000 meters, as far as possible to 110 meters above, the best to 130 meters above.  The field of vision is inversely proportional to multiple, and the aperture is directly proportional.  But more important is the design of the telescope’s internal structure.  The same multiple, the same caliber of the mirror, the field of vision will be very different.  

If you want telescopes for sporting events or theaters, you’ll need a compact telescope with a wide field of view.  They’re light and compact and don’t cause hand tremors.  This means that if you want a wider view, you should focus on telescopes with up to 10x magnification.  Because the larger the magnification, the narrower the telescope’s field of view.  

(5) Selection of the optical structure of the telescope  

Binoculars are divided into Paul type and roof type.  Paul type is a traditional structure, which has the advantages of simple optical structure, more manly, but large volume. Another point is that if it is not a big brand product, the repair rate will be high.  Roof type, complex structure, small volume, the disadvantage is the loss of transmittance, so the same clarity, roof type need better lenses and coating to Paul type brightness.  High-grade mirrors on market, give priority to ridge type more. There aren’t many high-def Paul telescopes on the market.

(6) High-quality optical components  

Binoculars use several types of optical elements: BK7 prisms, Bak4 prisms, and ED glass.  Binoculars with BK7 prisms are usually the least expensive because of the image quality they produce.  Bak4 prisms provide high-quality images and are commonly used for general purpose use in most binoculars.  The ED Glass (Ultra-Low Dispersion) binoculars produce the highest quality images, starting at $100 to $2.500 per binocular.  

If you see two binoculars with the same parameters but vastly different prices, that means one simple thing: the higher-priced binoculars are fog-proof, water-resistant, lightweight, and provide super-high-quality images.  It’s up to you to decide which one to choose.
