NOAO/NSO NewsletterJune 2009
This issue includes an article by Andrei Tokovinin about speckle interferometry at the SOAR telescope. Short-exposure images of a 1.08" binary star were co-added with re-centering on the global centroid (left), or on the brightest pixel, selecting the sharpest 10 percent of images (right). This latter technique, dubbed “lucky imaging”, is gaining popularity .
