8/11/05 NGC7635 The Bubble Nebula

The Bubble nebula is a planetary nebula, the cast off gas of a hot Wolf-Rayet star in the constellation of Cassiopeia. The star is blowing off it's outer layers and creating the bubble shaped nebula of ionized gas around it. This was the first nebula my son learned to recognize back when he was 3, 5 years later he remembers it instantly when he sees it. The seeing was very good on this night, it was hot but clear and very still, no twinkling!
