Well, as I have been threatening, I finally took the leap into astro spectroscopy. Here is my first attempt to achieve a stellar spectrum, Vega. This first image is the intensity plotted against wavelength. I have labeled the three major Hydrogen Balmer lines and their wavelengths. Equipment: 80mm Vixen apo refractor piggybacked onto the LX200GPS, a SPC900 video cam, a 100 line/mm spectral grating, and RSpec analysis and processing software. Seeing was not particularly good, so there is some baseline artifact in the smoothness of the curve. This the average of 150 frames.
