A method for precise centering on photographic star images is proposed. The image is moved only once across one scanning slit for the first coordinate and then across another slit for the orthogonal coordinate.

The photometric values are stored and treated in an on-line computer. The relative opto-mechanical simplicity suggests the application of the method to existing comparators.
