What is a good size telescope for beginners?

Telescopes that have 4 or 5 inch diameters are great for viewing solar system objects like the planets, our Moon, and Jupiters moons. Viewing Neptune and Uranus can be difficult with a scope this small but its not impossible. A telescope of this size is probably a good starting point for a complete beginner.

Which is better for beginners refractor or reflector telescope?

If you are interested in brighter celestial objects like the Moon or planets or a beginner, a reflector telescope is ideal. Refractors, on the other hand, can be great for visual too but they get very expensive for similar size apertures as reflectors.

Do astronomers use reflecting or refracting telescopes?

A refractor uses lenses within a tube to refract (bend) light. Its the type of long telescope which you might imagine old-time astronomers, like Galileo, using. Reflectors, on the other hand, use mirrors instead of lenses to reflect light. Most modern observatories use reflectors because their telescopes are so huge.

How big was the mirror in Herschels telescope?

48-inch The Great 40-Foot Herschels most ambitious telescope-making project – indeed, the most ambitious in history up to that time – was the construction of his great “40-Foot” reflector with its 48-inch (or 4-foot) diameter mirror (resulting in a focal ratio of f/10).

Can I see Saturns rings with binoculars?

With binoculars, you should get a sense for Saturns rings However, with binoculars or a small telescope — and good seeing — youll have the best chance all year to catch some really interesting detail. Even with binoculars, you can get a sense of the rings.

What are the disadvantages of a refracting telescope?

Disadvantages:Very high initial cost relative to reflector.A certain amount of secondary spectrum (chromatic aberration) unavoidable (reflector completely free of this) The colours cannot focus at one point.Long focal ratios can mean that the instrument is cumbersome.

What type of telescope can work 24 hours a day and even be used in the rain?

Hubble, the observatory, is the first major optical telescope to be placed in space, the ultimate mountaintop. Above the distortion of the atmosphere, far far above rain clouds and light pollution, Hubble has an unobstructed view of the universe.

Is the Hale telescope still used?

It was completed in 1949 and is still in active use. The Hale Telescope represented the technological limit in building large optical telescopes for over 30 years.

Who discovered Uranus?

William Herschel Uranus/Discoverers British astronomer William Herschel discovered Uranus on March 13, 1781, with his telescope while surveying all stars down to those about 10 times dimmer than can be seen by the naked eye. One star seemed different, and within a year Herschel realized the star followed a planetary orbit.
