Subject: Spectroscopy

Hi Folks;

I have had a couple of people on another list interested in adding Spectroscopy to Astro IIDC.

You can pick up some relatively inexpensive Grating for < $250 like:

The curve extraction / processing end is reasonably straight forward, although it is a fair bit of work to implement all of it (i.e. background sky subtraction, conversion of pixel to frequency based on known peak or absorption lines etc. etc.).

So I'm wondering if this is a feature people might use or not?

Thanks in advance..
