Uncle Al's Starwheels are inexpensive star maps, adjustable for any time of night in any month of the year. Such maps are also called planispheres. These Starwheels were created by the Hall's Hands-On Universe project, and based on the Lawrence Hall of Science (LHS) Sky Challenger, a set of 6 star wheels, formerly available through the Hall's Discovery Corner Store.
