Public star parties are a great way to promote astronomy
... Individual stars usually don’t look too terribly impressive through a telescope. They do tend to sparkle a bit and show some color, but to make them really astounding, tell your observers about the true scale of a star. Here’s one interesting way to do it: Our own star, the sun, is a pretty average ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
