Sun Gun Telescope, as featured in the August 1999 issue of Scientific American magazine, was designed so that large groups of people can view the sun safely - in particular it was created as a way to encourage children to become interested in astronomy. With this safe and portable device, both amateur science enthusiasts and professionals alike can observe sun spots. This book is a copy of Bruce Hegerberg's website www.sunguntelescope.com so that the instructions for building the Sun Gun and other astronomy related ideas he was working on will be preserved for all to enjoy for many years to come.
