To improve resolving power you want your telescope as wide as possible. Lenses larger than one meter are not really feasable while 10 meter mirrors have been built successfully. Lenses focus different colors (wavelengths) of light different places (chromatic abberation) making good imagery difficult. Mirrors don't care about the wavelegth.
What else can I help you with?
Why was reflecting telescope invented?
Early lens telescopes were small, expensive, made from delicate glass, and had fringes of violet color around bright objects. People could make mirrors, first of polished metal, then from glass coated with silver, and finally from different glasses coated with aluminum and other chemicals. These mirrors are larger, cheaper, and reflected light without making the color fringes. The reflecting telescope made modern Astronomy possible.
Early telescope makers compensated for chromatic aberration by?
Newton realized that mirrors do not cause chromatic aberrations, and built a telescope using them.
This telescope uses mirrors to gather and focus light energy?
Newtonian telescope
What telescope was the first to use many mirrors in a honeycomb patter to avoid the difficulties associated with large mirrors?
The Multiple Mirror Telescope (MMT) was the first telescope to use a honeycomb pattern of smaller mirrors to create the effect of a larger mirror. This design helped to minimize some of the difficulties associated with manufacturing and maintaining large, single-piece mirrors.
Does a reflecting telescope use mirrors?
yes
Is a telescope with incoming light passing through glass refracting?
Yes, a telescope with incoming light passing through glass does refract. The glass lenses or mirrors in a telescope refract light as it passes through, focusing the light to form an image.
How has the telescope changed?
mirror reflection: the glass lenses where producing a blurry image so they have been replaced by mirrors
Do all mirrors have to be made of reflecting glass?
No, mirrors do not have to be made of glass to be reflective. Mirrors can also be made using other materials like metal or polished stone that have reflective properties.
Can mirrors be made out of recycled glass?
Yes.
What type of telescope uses lenses or mirrors to gather focus light energy?
the reflecting telescope uses mirrors and lenses. The refracting telescope does not include the mirrors.

Are the mirrors in a babies dresser made of plexiglass?
Some are pleiglass but most are glass mirrors
Do magnets stick to mirrors?
No, magnets do not stick to mirrors because mirrors are made of glass and metal, which are not magnetic materials.
What is a catadioprtic telescope?
It is a telescope that uses lenses and mirrors.
What type of telescope uses lenses or mirror to gather and focus energy?
the reflecting telescope uses mirrors and lenses. The refracting telescope does not include the mirrors.
What type of telescope is a reflecting telescope?
one which reflects of mirrors
Why are mirrors considered the best reflections?
because it is made out of glass
