animation pulsating stars in Messier 3

This animation was build up from the Luminance frames taken for the photometry run which resulted in lightcurves of 15 pulsating RR Lyrea stars. In total 130 frames of 3 minutes each were used.

For the animation 10 frames were stacked together into 13 animation frames in total. The 13 frames are looped. The loop therefor represents a period of 6,5 hours.
