My name is Arnold de Bruin. I have been busy (off and on that is
) with astronomy for almost twenty years and since two years really found my "thing" with spectroscopy. I do have the SA100 and SA200 but more or less dived in buying the L200 when I discovered it was being build near where I live!Having a limited view of the sky, I have been busy since making spectra for BeSS. Recently I am trying to program a simulation of the Halpha profile and this way I hope to learn more about the physics involved.
Regards, Arnold
