Hi Dave
Yes I`d be happy to. Its a fascinating subject once the bug bites. Apologies to any Quantum physicists among us -
In the above spectrum the dark sections correspond to Hydrogen absorption lines where the electron moves outwards from the nucleus, it needs energy to escape the pull of the nucleus and takes it as photons hence the absence of light, conversely if the electron moves towards the nucleus it doesn`t need the energy and so emits it as photons. The electron can only be in one energy level at once and going from the ground state up a level would show a H alpha absorption line , going from the ground state two levels would show a H beta line and so on , I think I`ve got that
. I use a few different software packages Vspec, BASS, Isis all free I can get you the links if you want. I started out with a Star Analyser which screws into the filter on eyepieces,ccd`s and excellent little device to start off with.
My processing with other packages has sometimes missed a small dark or light area and I`ve wanted to get really into PI for some time as I think it could be very useful for spectroscopy.
HTH for now
Steve
BTW I think I posted this in the wrong section but I can`t seem to move it?
