What is bigger the sun or the hubble telescope?
The Sun; its diameter is 1392684 km while the HST has a diameter of 2.4 m only.
How many centimeters is the diameter of the Hubble telescope's mirror?
The primary mirror of the HST has a diameter of 2.4 m; the secondary mirror measures 30 cm in diameter.
What part of a reflecting telescope would you measure to find the apeture?
The diameter of the objective mirror, or of the tube if it has one.
What is the Lens aperture of the hubble telescope?
The Hubble Space Telescope is a reflector, so its objective is not a big-moose lens at the front;it's a big mirror in the back.The diameter of the objective mirror is 2.4 meters(7.87 feet), (94.5 inches).
What are the dimensions of the Hubble space Telescope?
The Hubble telescope is housed in an artificial satellite that is 13.2 m (43 ft) long, the primary mirror has a diameter of 2.4 m (7.9 ft) and has a collecting area of 4.5 m2 (48 sq ft).
What is the diameter of the chandra telescope?
It is 33 METERS in diameter
How much more light does a 3-m-diameter telescope collect than a 1-m- diameter telescope?
32 = 9.
Does the diameter of a telescope control its magnification?
No, you can change the magnification of the telescope by simply changing the eyepiece. The two most important powers of the telescope, light-gathering power and resolving power, depend on the diameter of the telescope, but it does not control the magnification.
How big is the lovell telescope?
The Lovell telescope has a steerable dish of 76.2 m (250 ft) in diameter
What is the biggest telescope?
The largest optical telescope in the world today is the Gran Telescopio Canarias (Grand Canary Telescope) in Spain, with an effective diameter of 10.4 meters. The world's largest individual radio telescope is the RATAN-600 in Russia, with the effective diameter of a 600 meter dish.
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 a western astronomical telescope worth?
The size of a telescope depends on many factors, but mainly, on its size. For example, a telescope with a diameter (of the main lens or mirror) of 100 mm will cost much less than one with a diameter of 500 mm.
How is the size of a reflecting telescope indicated?
The diameter of the concave mirror.
What happens to wavelength of light when in travels in a narrow tube narrower in diameter than the wavelength?
It grows a penis on its nose

What is the limiting visual apparent magnitude of a 200 inch diameter telescope?
The limiting visual apparent magnitude of a 200 inch diameter telescope is very large. It will reach a magnitude of over 500.
A telescope that suffers from chromatic aberration and has a low light gathering power is most likely?
a. a small diameter reflecting telescope.
