IC 351 is a far PN in Perseus constellation. It's been studied in the past by astronomers mostly on the spectral side, but it's never been object of complete studies and measurements about its structure. It appears as a tiny disk brighter at its center. Its rounded shape makes it look like planet Uranus.
The very few hi-res images found, mostly amatorial ones, show an interesting morphology where the central region is dominated by a bright elliptic ring characterized by two condensations, symmetrical to the central star. There's also a faint shell in the external region, mainly condensated on the minor ellipse axis. This morphology recalls a bipolar toroidal structure, but it's not sure because of the sayd lack of scientific measurements.
