  • Refracting Telescope Image Formation: Understanding the Objective Lens
    The objective lens of a refracting telescope forms the image.

    Here's why:

    * Objective lens: This is the primary lens at the front of the telescope. It gathers light from distant objects and focuses it to a point.

    * Eyepiece: This lens magnifies the image formed by the objective lens. It is positioned so that the image formed by the objective lens falls within its focal length.

    Therefore, the objective lens is responsible for forming the initial image of the distant object, and the eyepiece simply magnifies that image for viewing.
