LBV (luminous blue variables) or planetary nebula ?
Nebula by material ejection from a star, by different dynamics. LBV ejects material because is very massive and in the primordial stage of his life. The planetary ejects in death stage.
One ejects because of excess of material, other because it doesn't get process the nuclear fusion.
A more true image of nebula:

GSO 305 mm - Canon T3 - 16 x 3 min (48 min) ISO 800 - Skyglow filter - OAG - Coma corrector
note: DSLRs cameras tend to produce images of stars as chubby star. For this object, the image of the central star is disproportionate, not suitable.
