Quite dim, much exposure required, too much to mention.
Again, this was a bit harder than expected to get a pleasing result.
The explanation of this object is interesting though (stolen from AAO)
Other planetary nebulae show they can take a wide variety of shapes. Most show a distinctive and well marked symmetry, which can vary from more or less spherical, to doughnut-like annuli or to bi-polar, butterfly-like objects. Planetary nebulae also usually have well-defined boundaries, sometimes even a shell-like structure. For reasons that are not understood, NGC 1360 in Fornax defies all these conventions, yet its colour still clearly identifies it as a planetary nebula. The blue hue is oxygen, excited by the hot central star, and to the north-east of the nebula is a faint red smudge, probably traces of material ejected before the star became a true planetary nebula.
