If there’s a common thread running through today’s great amateur astrophotography, it’s Adobe Photoshop. This is a bit ironic, since the software is probably the only link in most imaging chains that can’t claim astronomical roots. So it’s not surprising that teaching specialized Photoshop techniques for astronomical imaging has become a cottage industry. This year alone we found five offerings worthy of mention. Three are books (one available only as a CD-ROM), while another is a work-in-progress set of DVD tutorials, and the last is a novel Web-based system that offers a range of services from streaming video tutorials to live one-on-one instructions. While all of them overlap in covering Photoshop basics, each has its own set of unique features. Check out the various websites to learn which one, or ones, might be best for you.
