Explain the working of a terrestrial telescope.

Suppose we take objects like stars. Then this object is at infinity and therefore it is real but inverted and diminished. This is acted as an object to the eyepiece. When this object image is fell within the focal length of the other convex lens by adjusting the eye piece. On the same side of forming the object image, the virtual image of the object image is also viewed through the eye piece.

What are the uses of a terrestrial telescope ?

Terrestrial telescopes are most commonly used for high magnification viewing over long distances in daylight. Image quality at different magnifications will depend on the optical system, the quality of glass used and the coatings applied to the surfaces of each lens.

How to Calculate Magnifying Power of a Terrestrial Telescope?

FAQ

What is Magnifying Power of a Terrestrial Telescope?
The magnifying power of a terrestrial telescope is the distance between the objective lens and the eyepiece and is represented as M=(1+fe/D)*fo/fe or Magnifying Power=(1+Focal length of an eyepiece/Least distance of the distinct vision)*Focal length of the objective/Focal length of an eyepiece. The least distance of the distinct vision (LDDV) is the closest someone with "normal" vision (20/20 vision) can comfortably look at something, The focal length of an eyepiece is the distance from the principal plane of the eyepiece where parallel rays of light converge to a single point and The focal length of the objective is typically between 2 mm and 40 mm. Magnification and numerical aperture are sufficient for quantifying the essential performance in a microscope.
How to calculate Magnifying Power of a Terrestrial Telescope?
