What can you see with a 4-inch refractor telescope?
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 you see with a 5 inch refractor telescope?
A 5″ refractor will be a large, powerful scope, requiring a substantial mount, but it will show wonderful views of planets, globulars, Messiers. It will also be quite expensive. A 5″ reflector will be much lighter, and probably a bit less satisfying than the 5″ refractor.
Is a 4-inch telescope good?
Telescopes that have 4 or 5 inch diameters are great for viewing solar system objects like the planets, our Moon, and Jupiter’s moons. Viewing Neptune and Uranus can be difficult with a scope this small but it’s not impossible. A telescope of this size is probably a good starting point for a complete beginner.
Is a 5 inch telescope good?
5-inch Telescopes offer exceptional resolution for their size. They can resolve double stars at . 91 arcseconds and can be magnified up to 254 times the human eye. 5″ Optical tubes also make exceptional light gatherers by allowing an observer to see 14.3 magnitude stars!
Is a 4-inch refractor good?
In general, a top-quality 4-inch refractor shows deep-sky objects about as well as a 5-inch reflector or catadioptric, and might even do a bit better on the planets. Most telescopes with apertures of 80 mm or less are refractors.
Can you see galaxies with a 4-inch telescope?
Galaxies are some of the most distant objects we can observe. Even if a galaxy is bright, the most you might typically see is its core with a 4-inch telescope. Don’t be discouraged though, this is where the fun really begins. As you get started in observing galaxies, a great starting place is its brightness.
Can you see Neptune with a 5 inch telescope?
Our eyes, even under perfect conditions, can only see objects as faint as magnitude 6.5. Planet Neptune, therefore, can only be seen with an optical aid, such as binoculars or a telescope.
