Life cycle of stars - Plotting your own HR diagram!

New exercise: Explore the star population inside an open cluster!

In this project you will be shown how to use Faulkes Telescope data to measure the intensity of light from the stars in a cluster (a process known as photometry), through different filters, and plot the colours of the stars on a 'colour-magnitude diagram'. Once a measure of how “red” or “blue” the stars are is made, more informtion about them can be obtained– massive stars are usually very blue (hot), intermediate mass stars (like the Sun) are yellow, and the very lowest mass stars are red (cool).
