A Guide to Astrophotography with DSLR Cameras by Jerry Lodriguss.

Latest Version - Fourth Printing - Updated March 21, 2009

This book on CD-ROM is a practical guide to astrophotography with digital single lens reflex
(DSLR) cameras. It explains how digital cameras work and everything you need to know
about how to take astrophotos with them. It also tells you how to process the images after
you have shot them, with step-by-step directions that will produce beautiful results.

Many people are disappointed when they look through a telescope and see faint deep-sky
objects as subtle gray smudges. They don't look anything like the gorgeous pictures they
have seen in books and magazines.

These amazing color images are made possible by the magic of long-exposure
astrophotography. Besides capturing what you can see visually, astrophotography allows you
to take pictures of things that are too faint to be seen, and colors that can not be seen at all.
Through digital processing, you can improve the color and contrast, and make these images

New DSLR cameras, such as the Nikon D50 and Canon EOS Rebel XT (350D), are now
reaching the price point where nearly everyone who has a telescope can afford one. The
extremely low-noise properties of this latest generation of DSLR cameras make them ideal for astrophotography.

Beginner astrophotographers often ask how to determine the best ISO and exposure to use
for their particular sky conditions at their observing site. This book tells you the answers to
these questions plus many others that you haven't even thought to ask yet!

Start out easy with a simple camera on tripod and shoot beautiful scenic shots of the Moon,
planets and star trails and constellations. Advance to wide-angle piggyback photography.
Master long-exposure deep-sky photography of nebulae and galaxies.

In the image processing chapter, you will learn how to work with simple, easy-to-take JPEG
images right out of the camera. You will learn how to remove vignetting, color correct and
enhance images, sharpen and reduce noise.

In the advanced image processing section, you will learn how to correctly calibrate raw
images with support frames such as dark frames and apply non-linear processing through
techniques such as digital development.

These basic and advanced image correction and enhancement techniques can be used with
images taken with any DSLR camera.

With this book you will discover how easy it is to:
* Take beautiful astrophotos with just a simple camera on tripod.
* Shoot the Sun, Moon, stars, nebulae, galaxies, and other celestial objects.
* Use your DSLR camera to shoot through your telescope.
* Determine the correct exposure and ISO to use for astrophotos.
* Focus your camera for razor-sharp images.
* Take short exposures of faint deep-sky objects and combine them into a longer exposure.
* Shoot raw format images and improve them with calibration frames.
* Perform brightness, contrast and color correction.
* Correct vignetting and uneven field illumination.

Video Tutorials and Practice Files Included!
More than 100 minutes of video tutorials with step-by-step instructions for complete image
processing and enhancement of JPEG and Raw images are included on the CD-ROM.
The original image files used in the tutorials are also included for you to practice with.

A Guide to Astrophotography with Digital SLR Cameras is not a traditional paper book. It is a
digital book on CD-ROM that you will be able to view on your computer in any internet web
browser such as Microsoft Internet Explorer, Firefox, or Opera.

"This book not only provides clear step-by-step details for beginners but also describes the
concept of digital imaging in a sufficient depth that it benefits advanced photographers. This is an incredible book.
