I would like to make a sundial with the dial face oriented in a due north-south direction and tilted upward toward the north celestial pole (41 1/2 degrees at my latitude), such that a perpendicular line through the dial face will point to the intersection of the celestial equator and the meridian. Looking upward through the plane of the dial face in the north-south direction, one will see the north celestial pole. Can someone tell me what kind of gnomon would give servicable results (vertical, perpendicular to the dial, etc?), where to place the gnomon, and the what the hourly markings on the dial would like like? Thank you for your assistance. Clyde Simpson
