NGC5189 is a bright (especially in OIII) planetary nebula with a beautiful, symmetrically twisted shape. It was discovered by James Dunlop in 1826. About 35′ away, PHR J1337-6535 is a faint, diffuse planetary nebula first cataloged 180 years later, in 2006.
The background emission nebulosity doesn’t appear to have a catalog entry, but it provides a nice visual contrast with this pair of planetary nebulae. This is an HOO palette image. I shot SII, but the SHO palette doesn’t look as nice for this area.
