95 metre aperture wide-field Schmidt camera was launched on a Delta II rocket into an Earth-trailing solar orbit 1,530km behind the Earth, where it will have an uninterrupted view of a 105 square degree section of sky in Cygnus and Lyra (see front cover image).
For the astronomical professional, this can mean 14-inch square glass plate negatives, Schmidt cameras weighing 5 tons, and 4-hour guided exposures, but an amateur can buy or make gas-hypersensitized Kodak Tech Pan and use almost any clock-driven telescope with a camera and lens riding it "piggyback" to take good pictures.
The same 48-inch Schmidt camera that did the previous survey will do this one.
