What can I see with a 4 inch refractor?
What can I see with a 4 inch refractor?
A 4-inch refractor, for example, is a great scope for planets, the Moon, and double stars. I know because I own one, and I wouldn’t part with it for love or money. This size scope, however, is a bit small for deep-sky objects such as nebulae, star clusters, and galaxies.
What can I see with a 80mm refractor telescope?
The 80mm objective lens and short 400mm (f/5.0) focal length are perfect for taking in wide swaths of the heavens, making it ideal for larger deep-sky objects. You’ll see spectacular star clusters, wispy nebulas, and expansive galaxies with this telescope, but it also excels at viewing objects in our solar system.
What can you see with a 150mm telescope?
150-180 mm refractors, 175-200 mm reflectors and catadioptric telescopes:
- binary stars with angular separation of less than 1″, faint stars (up to 14 stellar magnitude);
- lunar features (2 km in diameter);
- Clouds and dust storms on Mars;
- 6-7 moons of Saturn, planetary disk of Titan may be observed;
What can you see through a 5 inch telescope?
With a 5′ reflector, clean sky you reach objects some 12.58 mag. Beautiful globular clusters and planets are possible. You can observe some bright near galaxies, too. But nothing of deep-deep-sky.
What aperture do you need to see planets?
Experienced planetary observers use 20x to 30x per inch of aperture to see the most planetary detail. Double-star observers go higher, up to 50x per inch (which corresponds to a ½-mm exit pupil).
What can I see with a 70mm telescope?
The colorful bands and belts of Jupiter, as well as its four major moons, and the rings of Saturn are clearly visible in a 70mm telescope. Mars, Venus and Mercury are visible in a small scope as well, but are extremely reluctant to give up any detail because of their overwhelming brightness.

What is an astrophotography refractor?
The refractor is a renowned telescope design for imaging. So much so, in fact, that we recommend all beginner deep sky astrophotographers start with a small refractor due to their ease-of-use, high contrast images, and maintenance-free operation. All refractor telescopes are capable of astrophotography to some degree.
What are the different types of refracting telescopes?
Explore Scientific’s broad selection of refracting telescopes includes apochromatic refractors ranging in aperture from 80mm to 165mm, achromatic telescopes perfect for astronomy outreach and beginner refractors from brands like National Geographic and Discovery that are great for backyard astronomy.
What are the downsides of using a refractor telescope?
A few downsides of this telescope include no mount, a reportedly flimsy carrying case, and eyepieces that are good quality, but not the greatest (which you can always replace). Apochromatic: reduces chromatic aberration! 11. Explore Scientific FirstLight AR127mm Refractor Telescope
