What can you see through a 130mm telescope?
You will be able to see Moon, Jupiter, Mercury(looks like a star), Venus, Saturn pretty well. Mars would be disappointing a bit. Its too small. You will get 65x with a 10 mm.
What can you see with 100x magnification telescope?
100x – This is a great all around view of Jupiter, as you can see cloud detail on the planet, and see all four moons all in the same FOV. The Great Red Spot can also start being seen as well as a tiny orange colored dot on the planet (if it’s on the side facing Earth).
What can we learn about exoplanets from the James Webb Telescope?
When NASA’s James Webb Space Telescope launches in 2021, it will open a new window on these exoplanets, observing them in wavelengths at which they have never been seen before and gaining new insights about their nature. Exoplanets are close to much brighter stars, so their light is generally overwhelmed by the light of the host stars.
Will we ever be able to resolve exoplanets with space telescopes?
The James Webb Space Telescope (the world’s largest space telescope) costs almost 20 billion dollars and will not be able to ‘resolve’ exoplanets. EDIT: This actually could be done within somewhat more reasonable budget.
How do astronomers find exoplanets?
Astronomers usually find an exoplanet by inferring its presence based on the dimming of its host star’s light as the planet passes in front of the star – an event called a “transit.” Sometimes a planet tugs on its star, causing the star to wobble slightly. This illustration shows an exoplanet orbiting its much brighter star.
What size telescope do I need to see planets?
The max. useful magnification would be 500x. If your main objective when buying a telescope is to see planets, here are some general rules that will help when you select one. Start by choosing the biggest aperture your budget allows for. Pick the one with the larger focal length.
