This is a description of a CHOICE course.
This is an ideal course for new CCD observers. The course describes how to and why we need to calibrate photometric images. It will cover techniques for bias, dark, and flat fielding. A wide variety of user scenarios will be covered including tips for calibrating in poor observing conditions, with older equipment, different software types, etc. The content of the course will be based on chapters of Arne Henden's new unpublished book on CCD photometry. Access to a CCD camera and your own FITS images is required (AAVSOnet images will suffice).
