I present a new fast CCD stellar photometry {iraf} task called {qdphot} (Quick & Dirty PHOTometry) which quickly produces good CCD stellar photometry from two CCD images of a star field. {qdphot} was designed to be a data mining tool for finding high-quality stellar observations in the data archives of the National Virtual Observatory. {qdphot} typically takes just a few seconds to analyze two {Hubble Space Telescope} WFPC2 observations of Local Group star clusters. {qdphot} is also suitable for real-time data-quality analysis of CCD observations; on-the-fly instrumental color-magnitude diagrams can be produced at the telescope console during the few seconds between CCD readouts. More information about {qdphot} is available at the following website: [1mm] {http://www.noao.edu/staff/mighell/qdphot/} This research is supported by a grant from the National Aeronautics and Space Administration (NASA), Order No. S-67046-F, which was awarded by the Long-Term Space Astrophysics Program (NRA 95-OSS-16).
