Astronomical Image Processing
The module begins with a look at how images of the night sky are captured and stored using modern telescopes. After building a basic pinhole camera, we investigate how telescope optics are used to collect and manipulate light. Students then look at how captured observations, otherwise known as image data, can be viewed and analysed using basic image processing software. The module then investigates the use of colour filters, and how multi-filter images can be combined to create a 3-colour image. We finish with a practical activity that investigates a few of the more advanced techniques used by astronomers to explore the night sky.
