Here is my latest take on the Bubble Nebula SHO. It lies about 7000 LY's distant and is about 7 LY's in diameter. Hot stellar winds from the bright star at the 11 o'clock position, BD +602522, are plowing into the neighboring molecular cloud to form the bubble. It is projected that BD +602522 will go supernova withinin 10-20 million years.
Scope: AT 10" RCCF

Thanks for looking, hope you enjoy it!
