NGC7635 The Bubble Nebula
Certainly my best shot of the Bubble Nebula complex to date!
Lots of detail in this one!
It is an enormous bubble being blown into space by a super-hot massive star!
This was a 10 Hours of exposure through Astronomik 7nm & 6nm Narrow Band data Mapped out to RGB. Captured over 3 nights from my backyard observatory in Dayton. 6″ Celestron Newt.,Coma Corrector, & ZWO 174mm Cooled CMOS Camera, Nebulosity, Pixinsight, & Adobe CS.
NGC 7635, also called the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region emission nebula in the constellation Cassiopeia, The “bubble” is created by the stellar wind from a massive hot, 8.7th magnitude young central star, SAO 20575.
The Bubble is located in front of the HII Emission Region. It is located about 7000 to 11000 light years from Earth.
