This just happened a few minutes ago.. I was capturing the spectra of a star and the airplane just crossed the field and the lights got through the grating :) Cool Image!

Those who want to start on Spectroscopy of the stars, planets and more celestial bodies, the above software is the way to go! I am doing everything with this software and they also provide the grating you would be needing. This works with any kind of telescope and even with your simple DSLRs!
