ACKNOWLEDGEMENTS
Many thanks to all the people who have contributed along the way - to Thomas Stiren, Daniel Reiter, Vincent Schlatter and Anke Porten, rdts AG, for the new design of this site and technical support, to Markus Weber, who has been hosting my images on his own site www.astro-bilder.de for a long time and introduced me to website editing, to Les Cowley (Atmospheric Optics) for all his help and encouragement, allowing me to use simulations with his and Mike Schroeder’s HaloSim and IRIS software, Prof. Hans-Joachim Schlichting and Prof. Dieter Zawischa for answering my questions. Thanks also to the German ”Fachgruppe Atmosphärische Erscheinungen der Vereinigung der Sternfreunde e.V” with their homepage www.meteoros.de who aroused my interest in atmospheric optics a few years ago.
