How to buy the best stargazing telescope?Apexeloptic
Want to see the stars? The best stargazing telescopes can make the most distant stars feel within reach without leaving the back garden. However, stargazing is not cheap, especially if you want to do it properly, so it makes sense to research before buying to find out which telescope best suits your needs and ability level.
Read this guide on how to shop for the best stargazing telescope to help you to buy the best stargazing telescope.
How to buy the best stargazing telescope?
1. Caliber and focal length
The aperture refers to the diameter of the largest beam that can be received by the telescope objective lens. For common refraction telescopes, it can be simply understood as the diameter of the front round main lens. The focal length is the distance from the primary point of the telescope’s optical system to the primary focus, and its value is marked on the surface along with the aperture.
The magnification is actually obtained by dividing the focal length of the primary mirror by the focal length of the eyepiece. By dividing the focal length of the telescope by its aperture, you can also get the focal ratio, which is the same as the aperture of our common camera lens and reflects the telescope’s ability to collect light. The smaller the number, the better.
The larger the telescope, the fainter the object should theoretically be, and the smaller the angular distance between the two points. Therefore, aperture is the primary and even the only basic parameter to be considered when selecting a telescope.
2. Magnification and objective size
They are cited as a combination of two numbers, such as 10×50, which means they provide 10 times magnification and an objective lens with a diameter of 50 mm. The larger the numbers, the greater the magnification, and the more important it is for nighttime use, the more light they enter.
You can find professional astronomical binoculars that offer both telescopes, usually 20×80 or 25×100, but they are large and bulky and need to be mounted on a tripod.
That’s why the best astronomy hand-held binoculars are 10×50. This is a 10x magnification and 50mm diameter objective lens that lets in a lot of light, and all come in a lightweight package that is easy to carry and use.
Stargazing telescopes come in a wide range of sizes and weights, so consider where to store and where to use them. If storage space is at a premium, or if you are not prepared to carry heavy equipment around, consider the cost effectiveness of additional weight and size with higher magnification and resolution. If you’re watching primarily for entertainment, a smaller range might be the right choice for you.
The last word
Generally more advanced telescope will cost you more, but if you are ready to pay, then you will get more flexibility and better results, so you are unlikely to like use cheaper telescope quickly run out of passion. We recommend that if you’re looking for the most suitable for their own telescope, so buy you can afford the best telescope is meaningful; Too much scrimping can result in products whose performance falls short of what amateur astronomers should be awe-inspiring.
Spending a long night under the stars brings an element of intensity, so we are well adapted to cold winter nights and the clouds that often sweep over and block our view. So depending on where you are in the world, if you’re going to spend the nighttime hours necessary to get to know what’s above you, pack warm clothes, snacks, and a firm resolution. While it may be tempting, here’s a friendly reminder not to look at the sun through binoculars.
