What are the two basic types of telescopes What are their advantages and disadvantages?

There are two basic types of telescopes, refractors and reflectors….Disadvantages

All refractors suffer from an effect called chromatic aberration (“color deviation or distortion”) that produces a rainbow of colors around the image.
How well the light passes through the lens varies with the wavelength of the light.

What are the advantages and disadvantages of telescopes?

Advantages and Disadvantages of an Astronomical Telescope

It creates large magnification,
Superior resolving power per inch of aperture,
Its field of view is wide,
Superior performance in inferior conditions – image steadier,
The image is free from aberration, not reflections or interruption of the light path,

What is the disadvantages of telescope?

The disadvantages are mainly to do with the hassle of operating in space. It’s much more expensive, so you can’t have such a large telescope. If things go wrong it’s much harder to repair them. You can’t update the instruments so often so they quickly become out of date.

What are the disadvantages of telescopes?

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 are the different types of telescopes and their advantages?

Types of telescope and their advantage and disadvantage 1 Reflecting Telescope. Reflecting is most common telescope that maximum time comes under budget. 2 Refractor Telescope. Another universal and familiar telescope is refractor telescope. 3 Catadioptric Telescope. 4 Newtonian Telescope. 5 Dobsonian Telescope.

What are the disadvantages of a reflecting telescope?

They can also have a longer body which may impact on transportation and storage. They may also be more expensive, as large high quality lenses are more costly to produce. Cheaper lenses are more susceptible to aberrations. A reflecting telescope is similar to a refracting telescope, but just a little bit more complex.

What are the advantages of a fork mount telescope?

Instruments with a fork mount can be set up extremely rapidly 1. More expensive than a Newtonian of comparable aperture 2. Larger secondary mirror than with a Newtonian telescope

Are great optical telescopes any good?

Great Optical Telescopes are Big and Heavy. The best optical telescopes are quite big in size. They are not easy to carry around. In fact, you can forgo portability. You will need to dismantle the whole piece, carry it in your car or van and then set it up at the site where you wish to be.
