BD+303639 

 

This compact, very-low excitation, radiation bounded Planetary Nebula has been observed at six equally spaced PA with Telescopio Nazionale Galileo (TNG) + SARG (spectral range 4600-7900 A, slit 26.7 arcsec x 0.40 arcsec, spectral resolution 115000).

The fixed image at the start of the movie corresponds to the nebula as seen from Earth (North is up and East is left).
Each movie is about 170-290 Kby in size (avi) or 170-430 Kby (animated gif).
