a small telescope of low power and large field of view, attached to a larger telescope, for the purpose of finding an object more readily, called also a finder telescope or finder scope.

A slide ruled in squares, so as to assist in locating particular points in the field of vision.

or Finderscope A low powered auxiliary telescope mounted on a telescope used to make it easier to point the main telescope at some object.

A small telescope, ideally of wide field of view, that is fixed to the main telescope in order to facilitate the finding of objects.

A small, wide-field telescope attached to a larger telescope. The finder is used to help point the larger telescope to the desired viewing location.

A small telescope, piggybacked on a large telescope. The finder's scope gives a wider field of view compared to the large telescope. This helps us to locate an object we are interested in. The wide field of view of the finder allows an astronomer to "find" the object more easily. If everything is working correctly, when the object is in the center of the field of view of the finder, it should be visible in the telescope.

A finderscope (or finder) is a low-power telescope attached to (and aligned with) a higher-power telescope. The finder is used to locate objects in the sky easily; the higher-power telescope is then used for closer examination.
