Which is better refractor or reflector telescope?
Each telescope has its own advantage, for instance the refractor is better for observing the planets and the moon and the reflector for deep-sky objects (e.g. galaxies). However, the refractor suffers from what is known as chromatic aberration.
What are three advantages of reflecting telescopes?
List three advantages of reflecting telescopes over refractors.
- Allows all colors to be focused.
- Mirrors can be very large.
- Glass problems do not affect light entering in.
How big of a telescope do I need to see the flag on the moon?
The flag on the moon is 125cm (4 feet) long. You would require a telescope around 200 meters in diameter to see it. The largest telescope now is the Keck Telescope in Hawaii at 10 meters in diameter. Even the Hubble Space telescope is only 2.4 meters in diameter.
What magnification do you need to see Jupiter?
To look at planets like Jupiter and Saturn, you will need a magnification of about 180; with that you should be able to see the planets and their moons. If you want to look at the planet alone with higher resolution, you will need a magnification of about 380.
Is a 70mm refractor telescope good?
However, a 70 mm refractor (which collects 36% more light than a 60mm telescope) is considered by many amateur astronomers to be the minimum size for a good quality beginner refractor telescope. It is acceptable for observing bright objects like lunar details, planets, star clusters, and bright double stars.
How much magnification do you need to see cells?
About magnification: Most educational-quality microscopes have a 10x (10-power magnification) eyepiece and three objectives of 4x, 10x and 40x to provide magnification levels of 40x, 100x and 400x. Magnification of 400x is the minimum needed for studying cells and cell structure.
Can you see Jupiter with a cheap telescope?
Even modest equipment can offer a decent view of Jupiter. You don’t necessarily need to invest in an expensive telescope to observe Jupiter. As a matter of fact, the planet is so big and bright that I was able to see it along with 4 of its moons through an entry-level telescope (2.5″).
What is the best way to see Jupiter?
Great seeing conditions and a very dark night are must-haves. After that, you’ll need to make use of at least 100x magnification and probably >150x to have a chance of seeing it. The very best opportunities come when Jupiter is at opposition because it is closer, giving a much larger target for us to see.
Can you see Pluto with telescope?
Pluto requires a telescope to be seen. No telescope? Try NASA’s Night Sky Network to find star parties and/or astronomy clubs near you. And you don’t need a telescope to use your imagination.
