timwetherell Posted March 31 Share Posted March 31 (edited) 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 Edited April 5 by timwetherell grammatical error 23 Link to comment Share on other sites More sharing options...
