The Spectrohelioscope Network

Managed by Fredrick Veio and Chris Westland

Since 1970, Fred Veio has assisted many amateurs to build a spectrohelioscope (SHS) -- an instrument that allows you to image the sun in a very narrow band of color. His design is portable, compact, low cost, and was published in the January 1969 issue of Sky and Telescope.   His book on SHS (which can be downloaded from this page) appeared in 1972, followed by three more editions. A self made SHS will cost about $600. If an optical company makes the optics, total costs will be about $2000, including the grating. A professional SHS with long focal length optics, intricate machine shop parts, about $15,000.00.
