I am preparing to do an observing project for the AL Carbon Star (Variable Star) program. One of the observation areas is "The Stars Color". So... I am looking into Spectroscopy. (Use of Spectrograph...) Is anyone out there doing this, who might be available for some phone conversation ?? I am looking at a product called the Star Analyser 100 (alternate is 200) from a company called Shelyak (Europe). http://www.shelyak.com/dossier.php?id_dossier=45 Anyone with any experience with this product ?? Available for some phone conversation ?? Thanks... David M.
