This web page is presented for those who have an interest in the spectrohelioscope
and perhaps the desire to build one of these interesting instruments.
George Ellery Hale (1868-1938) invented the spectrohelioscope in 1924 which
allowed detection of sudden outbursts of activity on the sun. The
following photographs are of such an instrument, built by Leonard Higgins
with the support, and guidance of Fredrick Veio, author of the book,
"The Spectrohelioscope." This particular instrument has
been on display at the RTMC (Riverside Telescope Maker's Conference)
at Big Bear Lake, Camp Oaks in California, U.S.A., for the last two conferences,
1998 and 1999. It received a Merit award at the RTMC , 1998.
