Digital Astrophotography
At first glance, the challenge of astrophotography may
appear daunting. But not only are spectacular results
possible, they are easy to learn with the step-by-step
instructions provided in Stephan Seip's Digital
Astrophotography: A Guide to Capturing the Cosmos. Today,
amateurs can produce images that only twenty years ago
a
large professional observatory would have been proud of; and
this book shows you how.
Learn how to:
Set up your camera for optimum results
Focus your camera for razor-sharp images
Take beautiful night shots with a simple compact digital
camera, a tripod, and a telescope
Use a DSLR camera to shoot the Sun, Moon, stars, star
clusters, and nebulae through your telescope
Get brilliant images of planets with a Webcam
Capture remote galaxies with a charge-coupled device (CCD)
camera just like a pro
Also included are lessons on the processing that is done in
the "studio" after your shoot, including how to:
Shoot RAW format images and improve them with calibration
frames
Take short exposures of faint deep-sky objects and combine
them into a longer exposure
Perform brightness, contrast, and color correction
Make corrections to correct for vignetting and uneven field
illumination
Process your images for stunning results
Equipment requirements for astrophotography range from
nothing but a simple camera and tripod to a multi-thousand
dollar computer controlled telescope equipped with a CCD
auto-guider and separate guide-scope. Researching the best
equipment for your needs is a task in itself. Seip helps you
to sort out which cameras are best for the various celestial
objects, what to look for when buying a camera, and what
accessories you really need.
The rewards of this fascinating hobby, as the author says,
"Grants you unforgettable hours under the night sky; it
allows you to produce aesthetically rewarding and lasting
results. Astrophotography is a love-match between physics,
photography, art, and digital image processing. It is
exciting!"
