I will be teaching my Motion of the Heavens class for the Barony of Forgotten Sea on 1/26/2022 starting at 6:30pm. This class uses Stellarium to show the motion, as seen from earth, of the sky and objects in it, that any astronomical model will need to be able to explain. The class will be taught online. Information can be found on the Facebook event page.
