Hello All
 
   In this video I have covered all the Questions from comments from our subscriber.
   Following topics I have covered.

  A refractor telescope is a type of optical telescope that uses a lens as its objective to form an image. It works on the principle of refraction, where light is bent as it passes through different mediums. The main components of a refractor telescope include the objective lens, which gathers and focuses light, and the eyepiece, which magnifies the image formed by the objective lens.

The main components of a reflector telescope include:

Primary mirror: This is the largest mirror in the telescope and collects light from distant objects. It is typically concave (curved inward) to gather and focus light to a point.

Secondary mirror: The secondary mirror is smaller and positioned in front of the primary mirror. Its purpose is to intercept the light focused by the primary mirror and reflect it out of the side of the telescope to the eyepiece.

Eyepiece: The eyepiece is where the observer looks to view the magnified image formed by the telescope's optics. Different eyepieces can provide different levels of magnification.

The magnification of a telescope is determined by the combination of its focal lengths and the eyepiece being used. The formula to calculate the magnification of a telescope is:

The magnification of a telescope is determined by the combination of its focal lengths and the eyepiece being used. The formula to calculate the magnification of a telescope is:

Magnification = Focal length of telescope/ Focal length of eyepiece
