All these obsolete constellations have sources in the public domain describing or mapping the stars included. They either consist of stars not included in the official constellations (termed the amorphous areas by the Greeks), or overlap them, but portray something else.

Be sure and include an attributed copy of your source for the groups you select to observe. An example is shown below.

Or, if you use a text description when images are not available:


LIMAX, the naked Snail. A constellation offered to the astronomical world, and composed of certain conspicuous unformed stars near the foot of Orion, and under the Eridanus. It is a constellation of small extent, and contains only a few stars; …The conspicuous stars, of which the constellation Limax is composed, are nine…There is one at the extremity of the head, one at the hinder part of it near the out-line, and these are both large and bright ones. A little distant from these, near the opposite out-line, toward the hinder part of the head, are two small stars placed near one another, after these is a vacant space in the figure, till toward the lower part of the body, where there is in the outline a single large and conspicuous star; a little lower than this, and at the opposite out-line, stand three in a cluster together in the last, which is also a tolerably large and bright one, is at the tip of the tail

Note: if your geographical location inhibits the visibility of enough constellations (40) on this list to meet the requirements (e.g. Southern Hemisphere observer) please contact the coordinator.
