Scientific paper

For many years accessible to the professional astronomer only, nowadays speckle interferometry benefits also the double star amateur community, thanks to the introduction of affordable CCD detectors and powerful computers. Following some seminal papers, a description is given of a method to estimate double star parameters from speckle images captured using a webcam. Results show that diffraction-limited measurements are indeed obtained even with a relatively small telescope under moderate seeing conditions. An application has been developed to perform all the required speckle analysis presented here.
