Description
We present a World-Wide-Web-accessible database of astronomical images which suffer from a variety of observational problems, ranging from common occurences, such as dust grains on filters and/or the dewar window, to more exotic phenomena, such as loss of primary mirror support due to the deflation of the support airbags. Apart from its educational usefulness, the purpose of this database is to assist astronomers in diagnosing and treating errant images at the telescope, thus saving valuable telescope time. Every observational mishap contained in this on-line catalog is presented in the form of a GIF image, a brief explanation of the problem, and, when possible, a suggestion for improving the image quality.
