Resources and requirements for amateur spectroscopy If I wanted to move beyond just looking through my eyepieces and taking photographs of astronomical objects, what can I do do move into astronomical spectroscopy?
Are there any good resources for this?  Pitfalls?  And perhaps most importantly, what kind of initial outlay would I have to make?
 A: There's ready made equipment already out there, such as SBIG's Deep Space Spectrograph and Self-Guiding Spectrograph. Excluding the cost of a telescope you're looking at $3-4k to get into spectroscopy, though you can go cheaper if you buy a used CCD imager or if you DIY the spectrometer.
As far as resources, you're pretty much wading into deep water on this. Sky & Telescope had an article by a devoted amateur spectroscopist which has some useful tips. Additionally, there is a community of Amateur Astronomical Spectroscopy enthusiasts.
A: It's surprisingly easy and inexpensive to do astronomical spectroscopy. 
There is an active and growing amateur astronomical community that can coach you.  See the Yahoo forums like http://tech.groups.yahoo.com/group/staranalyser/?yguid=446659582. 
You need not spend much a lot of money to get exciting results.
