Check Out the Sun's Surface! You'll spend hours gazing in fascination as sunspots appear, move across the surface of the sun and then vanish.The Sunspotter is an innovative piece based on Johannes Kepler’s telescope which uses a convex lens. This device uses a system of mirrors and a powerful 62mm objective lens to project a brilliant 3 inch solar image onto a white viewing screen.Draw images of the sun during different times of day and on consecutive days.Take your experiment anywhere outdoors and even indoors where you can view the sun through windows, doorways, and skylights.CAUTION: Use with adult supervision. Keep fingers away from lenses and mirrors. Areas around the field lens can get hot. This device is used for indirect viewing of the Sun only.
