If you are covering the ‘Space Sciences’ component of the Australian Curriculum (Science) this term, why not get your students to take their own photograph of a celestial object (such as the Moon or a galaxy) using a robotic telescope? You don’t need any technical knowledge of how to use the telescope (it uses a simple ‘select and click’ menu) and you are emailed when the image has been taken. That said, for the technically minded, you can download free image manipulation software from the site if you want to.
