How good can astronomical images taken with a digital camera get?
The fact that digital camera images are appearing with increasing frequency in the Sky and Telescope magazine Gallery pages is a clear indication that in some cases at least, images from digital cameras can compete with film and CCDs. The digital_astro Yahoo! Group has a monthly challenge imaging competition. Many of the entries in these challenges are certainly among the best images group members have produced. A number of images from monthly challenge winners appear throughout this FAQ. A complete gallery of “best-in-group” and runner-up images from the challenges can be found at http://velatron.com/dca/gallery/, and should provide some idea of how good digital camera images can get.
