The Spectrohelioscope Network
Managed by Fredrick Veio, Chris Westland and Mike Rushford
Since1970, 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.

Here are a few sites:

They present eight levels of linear dispersion. Level five is 1A/mm.
Hale shs and Veio shs have 4A/mm, first order, at exit port. Using a
2 inch f.l. single lens eyepiece is 5X (10 inch standard/2 inch = 5x),
gives 0.8A/mm in first order, or about 0.3A/mm in second order.
jhuapl is Johns Hopkins University Aplied Physics Laboratories.
Level one is 16A/mm, level two is 8A/mm, and so on. All color.

They have solar spectrum, black and white,
excellent. The same site has a profile of the
photosphere of the sun atmosphere. Good.
INTRODUCTION TO THE SPECTROHELIOSCOPE (SHS) NETWORK
Fredrick Veio, July 2011
The home page of spectrohelioscope has 121 short articles. I numbered
the titles of the sentences and have detailed some of the topics, as photos
or text, whatever. You can find my discussions and photos more easily.
You do not need a degree in physics or chemistry in order to understand
the basics of the SHS, but about two years of college physics, chem and
astronomy are desirable. You do not need lots of shop tools, just basic
hammer, saws, vice, drill press, and so on. So do not worry. Just basic
wood construction, simple materials, will save much money and time.
There are some entry errors over the years, so I put error or nothing,
whatever, after the beginning of the article.
