Beschreibung:

Aimed at observers who don't examine deep-sky objects because they don't know what to look for, this volume focuses on these objects and provides photographs of all those discussed-exactly as they would be seen from amateur astronomers' suburban locations.
Illustrates exactly what deep sky objects will actually look like when observed, not as they look with enhanced imaging and processing
Provides various techniques to help develop the reader's observing skills, as well as tips to improve sketching and recording
Challenges observers to push the limits of their own observations
Observing Plans and Techniques.- Accessories and 'Pimping' Your 'Scope.- Sketching.- Constellation Observing Lists and Photos.- Observation Records.
Over the last 15 years or so there has been a huge increase in the popularity of astrophotography with the advent of digital SLR cameras and CCD imagers. These have enabled astronomers to take many images and, indeed, check images as they scan the skies. Processing techniques using computer software have also made 'developing' these images more accessible to those of us who are 'chemically challenged!' And let's face it - some of the pictures you see these days in magazines, books, and on popular web forums are, frankly, amazing! So, why bother looking through the eyepiece you ask? Well, for one thing, setting up the equipment is quicker. You just take your 'scope out of the garage or, if you're lucky enough to own one, open the roof of your observatory, align the 'scope and off you go. If you have an equatorial mount, you'll still need to roughly polar align, but this really takes only a few moments. The 'imager' would most likely need to spend more time setting up. This would include very accurate polar alignment (for equatorial mounts), then finding a guide star using his or her finder, checking the software is functioning properly, and c- tinuous monitoring to make sure the alignment is absolutely precise throu- out the imaging run. That said, an imager with a snug 'obsy' at the end of the garden will have a quicker time setting up, but then again so will the 'visual' observer.
