What problem do refractor telescopes have that reflectors dont?

There are several disadvantages with a refracting telescope.
1. Chromatic aberration is one, where all colours are not focused at the same point.
2. The mass of the lens, if large, could cause it to change shape as it is moved.
3. It is essentially impossible to have an optically perfect lens surface, and any minute imperfection causes 'confusion' of the light ray passing through that point.
4. Any lens surface will cause some reflection of light - light lost to the detector at the end point. You must have seen reflections of yourself, or of some landscape, from an ordinary transparent window glass. These reflections will re-reflect within a lens system, causing some optical confusion - loss of quality of the image.
Large modern reflector type telescopes avoid these problems by minimizing the number of glass surfaces between the incoming light and the recording surface. These days, the recording surface is usually a cmos, or similar, solid state detector.

Do Professional astronomical telescopes generally have a much greater magnification than the telescopes you can buy in stores?
Nope. they dont.
What are the advantages and disadvantages of X Ray telescopes?
i dont know find out yr self
Why are optical space telescopes able to see deeper into outer space than land based optical telescopes?
because they are above the Earth's atmosphere
Compare reflecting and refracting telescopes?
i dont know but ma whatever is wrong but i said what is the difference between refracting and reflecting
How do planets look through a telescope?
Telescopes are inanimate objects and dont' "see" anything. However, yes, reflector telescopes can be used to observe planets; the vast majority of large scopes are of the reflector type.

What are some types of telescopes?
there are two main types, all though there are five in total. the first one is called a refractor telescope, which uses a lense to bend the light into an eyepiece. these tend to fog up in winter time but give accurite pictures. a reflector telescope uses two mirors to reflect the light into the eyepiece. you can make these as big as you want and they dont fog up, but the immage can be distorted if the mirror angle is off by the slightest degree. of the two, i would say that the reflector is better than the refractor.there is a limmit to the size of the refractor.
How can they improve an optical telescopes resolution?
i dont know and ask me again
Why do you need to put some telescopes in space?
Telescopes on Earth have to look through the atmosphere (air) which distorts the image. Telescopes in space dont have to look through the atmosphere and so the image is a lot clearer.
Why do astronomers often place telescopes in dry areas?
so they dont get wet

What can you do to stay out of a problem?
dont get involved. If it is not your problem dont get into it. If it is your problem get some help if you can.
