This preliminary (March 2010) posting of the Sky Atlas is necessarily incomplete. Even the most nearly complete page (that of Andromeda) has only an incomplete listing of stars and other objects of interest. It does have a fairly detailed map of my own devising, a discussion of the mythology behind the constellation, a list of and links to nearby constellations, and even part of Bayer's (1603) maps of the constellation, so though incomplete, it does give an idea of what the rest of the Atlas will offer, when complete.
Preliminary pages have been posted for all modern constellations, and two former constellations, using public-domain maps from Wikimedia Commons, but none of the other pages is as complete as Andromeda's. Any significant improvements to the Atlas will be noted on my Recent Updates page, and RSS feed.
Navigation: You can move between constellation pages using the table of links below, links above each constellation map which list nearby constellations, or the arrows on either side of the "Celestial Atlas" link, just above the constellation name on each constellation page.
