2	Have You Ever Used Spectroscopy?
3	The Spectrum Tells A Story Stars Stellar classifications / HR Diagram Age of star Surface gravity Pressure Surface temperature Radial velocity Identify spectroscopic binaries Other Objects Galactic and Quasar redshifts Nebular compositions Comets and Planets
4	Equipment – Visual Spectroscopy Prism CD-ROM Project Star Spectrometer Naked Eye (Rainbows & Moonbows)
5	Equipment – Telescopic Spectrographs More Expensive SBIG SGS LHIRES III Baader DADOS Sivo Scientific Nu-View II Moderately Expensive SBIG DSS-7 Less Expensive DG Spectrum Filters Rainbow Optics Star Spectroscopes Rigel Systems RS-Spectroscope Paton Hawksley Star Analyser Build Your Own
6	Comparison of 4 Spectrographs
7	Acquiring Data With the SGS Use CCDSoft Guide on Slit Binning 1x4 Note that images are monochrome!
8	Processing Data Dark Subtract, Median Combine (CCDStack) Rotate if Low-Res Mode (IRIS) Wavelength Calibration (vSpec) Flux Calibration for CCD Response (equivalent to Flat Field)
9	Wavelength Calibration - H Edmund Scientific Lamps are used
10	Spectral Types
11	Identifying Stellar Composition
12	Emission Nebula The OIII emission lines were thought to be a new element in the early 20^th century, “Nebulium”.
