A 16-inch telescope is one of the largest telescopes for amateurs and hobbyist sky gazers. The large aperture can gather a large amount of light, making the views of planets and other night sky objects sharp. Serious astronomers also prefer this scope for the amazing views and optical performance. The magnification allows them to research […]
A 15-inch aperture offers a light-gathering power 4 times that of an 8-inch Schmidt-Cassegrain telescope. Amateurs will get amazing detailed views of the deep night sky objects with it. Obscure galaxies will appear with real color and details. However, there are not many options for a 15-inch telescope available on the market. Obsession Ultra Compact […]
14-inch telescopes offer clarity, contrast, and a flat field of view. They are great for astrophotography as they provide great views of planets and galaxies with details. On average, they have more than 2500x light gathering power, 2463-3916 mm focal lengths, and f/6.7-f/11 focal ratios. They offer exceptional resolutions for their size and can resolve […]
12-inch telescopes allow observers to see stars of 16.2 magnitudes. On average, they have 1200- 1525 mm focal lengths, and f/3.93-f/5 focal ratios. They can resolve double stars at 0.38 arcsec. They provide magnification power 600x times the human eye. They are great for astrophotography as they provide great views of planets and galaxies with […]
11-inch telescopes allow observers to see stars of 16 magnitudes. They can resolve double stars at 0.42 arcseconds. On average, they have 620-2800 mm focal lengths, and f/2.2-f/10 focal ratios. They provide magnification power 304x times the human eye. They vary in light-gathering power from 1589-1593x. Overall, they offer outstanding optical performance. What is an […]
10-inch telescopes are basically for amateur and hobbyist astronomers. On average, they have 1000-2500 mm focal lengths, and f/3.9-f/10 focal ratios. They provide six times the light-gathering power of a 4″ telescope and four times the light-gathering power of a 5″ telescope. You can get 10-inch telescopes from different brands in the price range of […]
9.25-inch telescopes are for amateur and hobbyist astronomers. On average, they have 2350-2500 mm focal lengths, and a focal ratio of f/10. They provide 33% more than the light-gathering power of an 8″ telescope. Only the Celestron brand offers different types of 9.25 inch-telescopes. You can get 9.25-inch telescopes in the price range of 1,899$-8,320$. […]
8-inch telescopes are basically for amateur astronomers. Overall, they provide 800-2415 mm focal lengths, and a range of focal ratios from f/4-f/11.5. They offer twice the light-gathering power of a 4″ telescope. 8-inch telescopes allow magnification up to 300-480x. You can get 8-inch telescopes from different brands in the price range of 570-5,000$. What is […]
7-inch telescopes are basically for amateurs though there are some advanced telescopes for professional astronomers with this aperture. Overall, they provide 500-2700 mm focal lengths, and a range of focal ratios from f/2.8-f/15. They can magnify objects 356 times the human eye. They also can resolve double stars at 0.65 arcsec. You can get 7-inch […]
