Subject: Re: [Astro_IIDC] Spectroscopy

As I mentioned in an earlier email, I would definitely be interested in spectroscopic functionality in Astro-IIDC.   

Here is the URL for a Rainbow Optics grating:

http://www.starspectroscope.com/

The difference between this one and the Star Analyser, is the Rainbow Optics is 200 lines/mm, while the Star Analyser is 100 lines/mm.

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..
