Constellation Editions

CSOG covers all 88 constellations in three telescope aperture classes. These aperture categories are indicative. To observe all of the objects in an edition that matches the aperture of the telescope you use, truly excellent observing conditions may be required.

The constellation of Serpens is divided into separate content for Serpens Caput and Serpens Cauda.
