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 outstanding!
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.
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
