You mean a "planetary nebula" that forms around a star that ha had a nova ? ?
We see those because of re-radiated light from the central star :
"A mechanism for formation of most planetary nebulae i thought to be the following: at the end of the star life, during the red giant phase, the outer layer of the star are expelled via pulsations and strong stellar winds. The exposed hot, luminous core emits ultraviolet radiation that ionizes the ejected outer layers of the star. This energized shell of nebulou ga reradiates the absorbed ultraviolet energy at visible frequencies and appears a a planetary nebula."
That i from here : http://en.wikipedia.org/wiki/Planetary_nebula
Im thinking something would be visible from the vantage point of the central star, but it would faint and not the beautiful shape we see around other star. More likely just a glowing "cloud".
