Hi Mike,

Those are great looking spectra and an interesting comparison. Nice to see the BAA collection being put to good use.

If you fancy taking things to the next level then there is a wealth of free spectroscopy processing software now available. I’ve used BASS and ISIS, but there is also RSpec, Vspec and I think maybe a few others. These can produce a graph of a spectrum and help you to identify elements, along with various other functions.

I’m still a bit of a beginner in spectroscopy myself, starting out in September last year, but if you want pointers to any of the software then please let me know.

Do you know about the BAA spectroscopy workshop on 10th October at the Norman Lockyer observatory? It is being organised by the Variable Star Section noting it is more about an introduction to spectroscopy rather than variable stars.
