A Wantedin astronomy, is a small eyeglass with a wide field of vision, used to facilitate the direction of a powerful telescope.

It is mounted in parallel on the main axis of the telescope and has a grid, usually consisting of two crossed wires.

The star to be observed is first located with the search engine, so that the image of it falls on the reticle, in this way, if the axis of the search engine is perfectly parallel to that of the telescope, the image must appear at the same time in the eyepiece of the own telescope

The view through the search engine is also reversed - as in the main telescope. However, the search engine usually has a cross drawn to locate the midpoint precisely and has a wider field of vision than with the main telescope. This is due to the lower amplification of the Finder.
