Today's photographic equipment allows amateurs to take pictures of
the stars that far surpass images taken just a few decades ago by
even the largest observatories-and this book will teach you how.
Author and world-renowned astrophotographer Thierry Legault teaches
the art and techniques of astrophotography: from simple
camera-on-tripod night-scene imaging of constellations, star
trails, eclipses, artificial satellites, and polar auroras to more
intensive astrophotography using specialized equipment for lunar,
planetary, solar, and deep-sky imaging. Legault shares advice on
equipment and guides you through techniques to capture and process
your images to achieve spectacular results. Astrophotography
provides the most thorough treatment of the topic available. This
large-format, richly illustrated book is intended for all sky
enthusiasts-newcomers and veterans alike. Learn how to: Select the
most useful equipment: cameras, adapters, filters, focal
reducers/extenders, field correctors, and guide telescopes Set up
your camera (digital, video, or CCD) and your lens or telescope for
optimal results Plan your observing sessions Mount the camera on
your telescope and focus it for razor-sharp images Polar-align your
equatorial mount and improve tracking for pin-point star images
Make celestial time-lapse videos Calculate the shooting parameters:
focal length and ratio, field of view, exposure time, etc. Combine
multiples exposures to reveal faint galaxies, nebulae details,
elusive planetary structures, and tiny lunar craters Adjust
contrast, brightness, light curves, and colors Postprocess your
images to fix defects such as vignetting, dust shadows, hot pixels,
uneven background, and noise Identify problems with your images and
improve your results
