A close-up of the Cygnus Bubble Nebula PN G75.5+1.7

The nearly symmetrical shape of this elusive object is very similar to planetary nebula Abell 39, discovered by George Abell in 1966.
The circumference of PN G75.5+1.7 outlines a delicate edge beautifully illuminated and comparable to that of Abell 39. The interior of the
nebula is unlike the partially opaque Abell 39 however, and only hints at the barest form of structure with faint wisps of OIII nebulosity
in its southern and eastern regions. Note the distinctly small blue star at the "center" of the Bubble. Could this be the central star of PN G75.5+1.7?
