This page contains examples of prior work in the field of spectroscopy using equipment at the Northwood Ridge Observatory, Phillips Exeter Academy Grainger Observatory and elsewhere. Taking CCD images is interesting and results in some lovely pictures to hang around the house and to show friends, but there is a lot more that an amateur astronomer can do these days. All of the advanced equipment that is now available offers the amateur a whole host of projects to choose from. Spectroscopy is now easily within reach of anyone with a small telescope! The spectra captured at the Northwood Ridge Observatory were done using scopes ranging in size from 106mm to 8″, a Starlight Xpress MX-5c CCD imager, an SBIG ST-7 and a Rainbow Optics transmission grating. Any good CCD imager will do, and it does not need to be a color imager. The CCD camera is also optional. The Rainbow Optics unit is meant to be used at the eyepiece, and anyone can find absorption lines in bright stars using this device. Thus, an amateur can collect spectral data by sketching what is seen at the eyepiece.
To see these images properly, you should adjust your monitor to see the following 17 greyscale steps (solid black to white):
