The sun in h-alpha with a spectrohelioscope booklet for sale

[Dawson]

I am sorting through piles of stuff which has acumulated in my garage and have this interesting booklet which I have listed for sale on ebay; proceeds to the Society for the History of Astronomy Library, of which I am the Librarian.

I will also share the link in the solar section whats app group.

Thanks.
