Description:
The nebula is displayed in the Hubble (SHO) pallette. Exposure times were SII 12.5 hrs, H-α 8hrs, OIII 26 hrs. The deeper exposures are needed to display the outer shells of expanding gas. To display the stars with their correct colours, data from an earlier RGB imaging run was used, exposure times being: Red 3.5 hrs, Green 3 hrs, Blue 4 hrs. In post-processing the stars were removed from the narrowband image and replaced by those from the broadband run using the tools in PixInsight.
