NGC 6543

 

Preliminary results for the Cat's Eye Nebula, based on echellograms at nine position angles taken with Telescopio Nazionale Galileo (TNG) + SARG (spectral range 4600-7900 A, slit 26.7"x0.40", spectral resolution 115000). For the multicolor projection, the fixed image at the start of the movie corresponds to the nebula as seen by Hubble telescope (North is up and East is left). Later on, the image blurs and rotates.
Each movie is about 150-300 Kby in size.
