Polaris - Time lapse of a Cepheid type variable

Recommended Posts

Wanted to create a time lapse of a Cepheid variable star for a talk I'm giving and thought Polaris was probably the easiest target. This is 4 frames at 24 hour intervals covering its 4 day period. It only varies by about 1/4 magnitude but I think the pulsing came out quite well in the movie :)
