Rajiv Gupta, Auriga Imaging (Composite Digital Techniques for High-Resolution Astrophotography with Film). Over the past 8 years has been developing methods to produce finely detailed colour images using the black-and-white wonder film of astrophotography, Kodak's black-and-white Technical Pan. Rajiv is co-developer of RegiStar software, which automates the alignment of digital images. He is also editor of the RASC's Observer's Calendar, in which many composite images have appeared.

The best deep-sky images now being produced are composites, formed by combining two or more individual exposures into a single image. Thanks to various powerful computer programs on the market, composite imaging is now easy. With several examples Rajiv will demonstrate some of these exciting techniques as applied to film.
