1200006: Sunspotter

DESCRIPTION:


Check Out the Sun's Surface!


The Sunspotter is an innovative, wooden, folded-Keplerian telescope that uses a system of mirrors and a powerful 62mm objective lens to project a brilliant 3" solar image onto a white viewing screen.


Easily aligned to the sun in seconds, you'll spend hours gazing in fascination as sunspots appear, move across the surface of the sun and then vanish.


Trace the images and compare the changes the sun's surface goes through hour by hour or day by day. Elegantly simple to use, easy to set up, and completely safe.
