Unit guides



  • First semester 2017 (Day)


This unit gives students theoretical background and practical experience in modern observational astronomy. ASP3231 students study telescope optics, spectroscopy, CCD imaging, image processing, statistics, astronomical distances, stellar evolution, extra-solar planets, neutron stars and galaxies. An observational project, including an astronomical observing session and analysis of the observations, comprises a substantial component of ASP3231.


On completion of this unit students will be able to:

  1. Explain and understand concepts taught in the unit, including astronomical instrumentation, data processing, photometry and spectroscopy;
  2. Describe how we observe celestial objects across the electromagnetic spectrum and how these observations are used to understand the nature of celestial objects;
  3. Evaluate the accuracy of astronomical instrumentation and observations, including angular resolution, spectroscopic resolution and photometric precision;
  4. Apply their knowledge to execute an observing program and use astronomical imaging to understand the nature of a celestial object;
  5. Present and communicate the results of an astronomical observing program.
