The Soap Nebula, PN G75.5+1.7, was discovered by the amateur astronomer Dave Jurasevich back in 2008. This faint nebula can be detected using narrow band filters with long integration times. We can find it near the popular Crescent Nebula, NGC6888.
Both nebulae are surrounded by huge clouds of gas and dust in the constellation of Cygnus. NGC 6888’s central star is classified as a Wolf-Rayet star (WR 136). This star will become a supernovae in the near future.
NGC 6888 is located some 5,000 light-years away from Earth.
To capture this image I used Hα and [OIII] narrow band filters in order to capture the faint details of this amazing deep sky structure.
