How big a telescope do I need to see Jupiter?

Regardless of telescope type, the optics should be perfectly collimated. A well-made 5-inch refractor or 6-inch reflector on a sturdy tracking mount is really about the minimum for serious Jupiter observing. Larger instruments will allow scrutiny of fine detail and subtle low-contrast markings.

How powerful does a telescope have to be to see planets?

If you purchase a cheap telescope to see planets, assume a usable maximum magnification of around 70% the theoretical maximum. Using the example from point 2 above, 70% of our 200x magnification is actually 140x usable magnification.

Do astronomers use reflecting or refracting telescopes?

Astronomers prefer reflecting telescopes over refracting telecopes for several reasons. … It is easier to make a large reflecting telecope than a large refracting telescope. A larger telescope means more light can be gathered and fainter objects can beseen. Older telescopes tended to make mirrors and lenses out of glass.

Can you see Venus with a telescope?

Although any telescope (or steadily-held binoculars) will allow the phases of Venus to be seen, the planet is a notoriously difficult one to observe, for three main reasons. … Thirdly, the planet itself is permanently cloaked in thick cloud, so its surface features are never visible through telescopes.

What can I see with a 60mm refractor telescope?

60mm (2.3in) to 70mm (2.8in) aperture or equivalent With telescopes of this aperture size, you’ll be able to see the moon and her craters, as well as some of the bigger planets.

Which is better telescope reflector or refractor?

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. … The third type that I mentioned was the Schmidt Cassegrain telescope.

What are the disadvantages of a reflecting telescope?

Reflecting telescopes have a few disadvantages as well. Because they are normally open, the mirrors have to be cleaned. Also, unless the mirrors and other optics are kept at the same temperature as the outside air, there will be air currents inside the telescope that will cause images to be fuzzy.

What magnification do you need 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.

Do refracting telescopes have mirrors?

You can find quite a few different designs. Reflecting telescopes use mirrors to gather the light. Refracting telescopes use lenses. There are different kinds of reflectors, but in general the refractors all follow the same basic design.

Is 70mm good for telescope?

70mm is a good daytime telescope size. Make sure she never looks towards the sun with it. For night work you need a 90mm or above.

What size telescope do I need to see the rings of Saturn?

Viewing Saturn’s Rings The rings of Saturn should be visible in even the smallest telescope at 25x. A good 3-inch scope at 50x can show them as a separate structure detached on all sides from the ball of the planet.

What magnification do I need to see the rings of Saturn?

Saturn’s rings should be visible in even the smallest telescope at a magnification of 25 times. A good 3-inch scope at 50x magnification will show the rings as distinctly separate from the ball of the planet.
