For amateurs, reflecting telescopes (with one parabolic and one flat mirror) can be made cheaply at very large sizes. For example, a $3000 telescope with lenses might be 4 inches wide and one with mirrors might be 16 inches wide. This also makes it possible to build massive reflectors for research purposes, like the planned 38-metre-wide E-ELT.
What else can I help you with?
What power of an optical telescope is most affected by light pollution?
A small aperture.
What property of an optical telescope is associated with sharper images?
The sharpness of images in an optical telescope is often associated with its resolving power, which is determined by the size of the telescope's objective lens or mirror. A larger objective size allows the telescope to collect more light and resolve finer details in the observed objects.
Which power of a telescope is the least important?
The least important power of a telescope is likely the magnification power. While magnification allows you to zoom in on objects, other factors such as aperture size, optical quality, and clarity are more crucial for obtaining clear and detailed images.
What does optical power mean?
Optical power refers to the ability of a lens or optical system to converge or diverge light. It is typically measured in diopters (D) and indicates the strength of the lens in focusing light onto the retina. Positive optical power converges light (useful for correcting hyperopia), while negative optical power diverges light (useful for correcting myopia).
What does the light gathering ability of a telescope depend on?
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.

Which power will allow you to see more the object?
Increasing the resolution or magnification of the optical instrument, such as a microscope or telescope, will allow you to see more details of the object.
What is the Definition of resolving power?
The ability of a microscope, telescope, or other optical instrument to produce separate images of closely placed objects. It's also possible to relate this to optical instruments such as computer screens or digital cameras where a higher resolution (more resolving power) will produce a clearer image.
What makes a telescope powerful?
The light-gathering power of a telescope is determined by its aperture, which refers to the width of a telescopes primary mirror or objective lens.
What is the difference between a High Power telescope and a Reflecting telescope?
A Reflecting telescope has a lot of zooming technologies and the High Power telescope is highly powered.
Why does the light gathering power of a telescope vary?
The light gathering power of a telescope is directly proportional to the area of the objective lens of the telescope.
How do you calculate optical power?
Optical power is calculated by dividing the energy of the light beam by the time it takes to deliver that energy. The formula for optical power is: Power (P) = Energy (E) / Time (t). The unit of measurement for optical power is watts (W).
What does optical power mean?
Optical power refers to the ability of a lens or optical system to converge or diverge light. It is typically measured in diopters (D) and indicates the strength of the lens in focusing light onto the retina. Positive optical power converges light (useful for correcting hyperopia), while negative optical power diverges light (useful for correcting myopia).
Does a curved mirror necessarily have optical power?
Yes but a complex curve will not have a simple or single optical power.
Does a thinner and less convex lens have a shorter focal length and low optical power?
It is not necessary that a thinner convex lens have less optical power or a thicker lens has more optical power
