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 telescope 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 and telephoto lenses. Separate chapters extensively discuss cameras, lenses, filters, and photographic accessories suitable for astrophotography as well as the guiding techniques needed to accurately track moving celestial targets. Additional chapters also detail powerful astrographs such as the Schmidt camera, and describe a number of homebuilt devices which can enhance the convenience and versatility of wide-field astrophotography. Further chapters discuss the characteristics of photographic film, how to test a film for its suitability f

This image of Russian cosmonauts Oleg Kononenko and Anton Shkaplerov, both Expedition 30 flight engineers, was taken during a spacewalk on Thursday, Feb. 16, 2012. During the six-hour, 15-minute spacewalk, Kononenko and Shkaplerov moved the Strela-1 crane from the Pirs Docking Compartment in preparation for replacing it in 2012 with a new laboratory and docking module. The duo used another boom, the Strela-2, to move the hand-operated crane to the Poisk module for future assembly and maintenance work. Both telescoping booms extend like fishing rods and are used to move massive components outside the station. On the exterior of the Poisk Mini-Research Module 2, they also installed the Vinoslivost Materials Sample Experiment, which will investigate the influence of space on the mechanical properties of the materials. The spacewalkers also collected a test sample from underneath the insulation on the Zvezda Service Module to search for any signs of living organisms. Both spacewalkers wore Russian Orlan spacesuits bearing blue stripes and equipped with NASA helmet cameras. Image Credit: NASA Read More
