IC1848 - Emission Nebula in Cassiopeia
Emission Nebula in Cassiopeia
  • Description: Index Catalogue entry 1848 is a rather large but faint nebula in Cassiopeia. Also known as LBN667, The Baby Nebula or the Soul Nebula, it is located next door to the Heart Nebula, IC1805. This shot is my first bi-colour shot taken from within the city limits, using narrow band filters to get around light pollution. However, it requires long exposures!
