schematic how to use the Eclipse Sundial with a telescope projection

Place on screen behind Telescope. The orientation of your telescope will change as you follow the sun in the sky. Because of this telescope movement, you may have to periodically adjust the paper so Upwards is up, and the leveling line is level to the horizon. These instructions may not work for newtonian reflectors or telescopes using an eyepiece mirror diagonal.
