Popularity of Technique
Both amateur and professional astronomers have begun to use this technique. Modern webcams and camcorders have the ability to capture rapid short exposures with sufficient sensitivity for astrophotography, and these devices are used with a telescope and the shift-and-add method from speckle imaging (also known as image stacking) to achieve previously unattainable resolution. If some of the images are discarded, then this type of video astronomy is called lucky imaging.
Many methods exist for image selection, including the Strehl-selection method first suggested by John E. Baldwin from the Cambridge group and the image contrast selection used in the Selective Image Reconstruction method of Ron Dantowitz. The recent development of EMCCDs has allowed the first high quality lucky imaging of faint objects.
Due to the large amounts of data that must be processed in order to increase systematic gain, Lucky imaging is amenable to distributed computing methods. Semi-automated image processing methods like Galaxy Zoo implement can be extended and fully automated for distributed computing systems like BOINC.

Famous quotes containing the words popularity of, popularity and/or technique:
“The popularity of that baby-faced boy, who possessed not even the elements of a good actor, was a hallucination in the public mind, and a disgrace to our theatrical history.”
—Thomas Campbell (1777–1844)
“A large part of the popularity and persuasiveness of psychology comes from its being a sublimated spiritualism: a secular, ostensibly scientific way of affirming the primacy of “spirit” over matter.”
—Susan Sontag (b. 1933)
“The audience is the most revered member of the theater. Without an audience there is no theater. Every technique learned by the actor, every curtain, every flat on the stage, every careful analysis by the director, every coordinated scene, is for the enjoyment of the audience. They are our guests, our evaluators, and the last spoke in the wheel which can then begin to roll. They make the performance meaningful.”
—Viola Spolin (b. 1911)
