Spectra of Stars in and around M45 the Pleiades
12.5" Newtonian and Star Analyzer

Perhaps one of the most interesting groupings of stars in the sky, M45 ranks high on the list of both visual and imagers for detailed study. Here, after being inspired by a similar type of graphic on Christian Buil's page, My version includes a few more stars, and I used RSpec for the spectra graphics. Here, I have also enlarged the spectral line a bit to make the data more apparent on the full screen version. The background was taken with my 8 inch Schmidt camera on film.
