ATM Building a spectrohelioscope

["Sylvain Rondi" <Rondi@wanadoo.fr>]

Hello everybody,

First, as a new user of this list,  let me introduce myself: I'm a french
student at an engineering school, and an active builder of telescopes
(several Newtons, 2 Schmidt cameras, ...).
I plan to build a spectrohelioscope using a grating (similar to the one
described in Amateur Telescope Making Book One Part IX), but I'd like to
build a transportable one (not in a building like in the book). I'd like to
know if somebody has built such a spectrohelioscope and where I could find
informations on this subject (article, web page, ...).
Thank you,

        Sylvain Rondi.
