Astronomy: Stellar Spectra

Conduct a physics investigation like a professional physicist using simple low-resolution stellar spectroscopy. Learners will use 100 line per mm blazed gratings on our telescopes to collect spectra from several different main sequence stars, before using specialised software to calibrate and analyse their spectra. They will identify key absorption features such as the Hydrogen Beta line, peak wavelengths and identify the spectral class. Weather permitting, learners will also learn to control and drive the telescopes to observe several objects visible on the night.

Please note: 5:00 pm session is available May through to July. The 6:30 pm session is available April through to September and the 8:30 pm session can be booked all year.
