The Jellyfish Nebula (IC443)
The Jellyfish Nebula is an expanding bubble-shaped cloud of debris from a massive star that exploded over 30,000 years ago. The nebula is about 5,000 light-years distant in the constellation

NGC 7635 The Bubble Nebula
The Bubble Nebula is a shell of gas surrounding a massive O star (BD+602522) which can be seen in the upper right quadrant of the bubble. The star is several
Wide-field image of IC1318 in Cygnus
The bright star projected at bottom centre of this image is the supergiant Gamma Cygni (aka Sadr). It is located only 750 light years away and so is not directly
IC1396 – Combined Ha and OIII bicolour composite
This is a colour enhanced version of the Hydrogen Alpha image of IC1396 in Cepheus acquired on 17th July 2015. The image is made up of an additional four hours
