So let me see if I got this right. This is a
PREsupernova, and it's blown a 30 light year wide hole in the interstellar medium?
When it finally does go nova, I'm guessing it will be one heck of a thump...
I used paint.net to overlay a screen shot of the image on the Starry Night view of the sky from my latitude ( i.e. Chicago . ) Note the nebula covers about 1/2 degree of declination, so it's about the size of the moon ... funny I never noticed it !
