WideField Astrophotography Exposing the Universe Starting With a Common Camera Author:Robert Reeves Wide-field astrophotography is an area where the beginner can bypass the complexities of prime focus telescopic astrophotography yet still excel and achieve good results quickly. Exquisite prime focus close-ups of galaxies and faint nebulae are attractive showpieces, but the art and technicalities of photographing such objects through a telesco... more »pe are intimidating to the beginner. In high-resolution telescopic photography, the cost of the specialized equipment, the complexities of focusing fine, often invisible detail through the telescope, and guiding with extreme accuracy to achieve worthy results are obstacles to a novice sky shooter. Simpler non-telescopic wide-field astrophotography is an alternative that anyone who owns a camera can enjoy. Today, may well be the Golden Age of Astrophotography. At no time in the past has there been a wider range of films, both color and black and white, that do well when exposed to the night sky. Many of these films capture images in a few minutes that just a few years ago required lengthy exposure by an experienced astrophotographer. Some of these films can be processed in a 1-hr labgone is theera of waiting days to see your results. This text then introduces techniques needed to mount ordinary 35-mm and medium format cameras atop an equatorially-driven telescope in order to produce stunning portraits of constellations, the Milky Way, bright nebulae, and star clusters using wide-angle« less
