StarSpectra Makes Stellar Spectroscopy Small Enough to Try

Field notes

The project combines a 15° circular objective prism with amateur astronomy equipment and a 350–900 nm stated range. Its processing sequence runs from video-frame stacking through alignment, one-dimensional spectrum extraction, wavelength calibration, and Harvard-scheme classification. The listed examples include Vega at A0V and 9602 K, Arcturus at K1.5III and 4286 K, and Betelgeuse at M1-2Ia and 3500 K. The page attributes the work to two students and an advisor.
