NGC 7635, the Bubble Nebula, is an H II region emission nebula in the constellation Cassiopeia. This is a very faint object seen visually through a telescope but astrophotography clearly reveals the bubble. The “bubble” is created by stellar wind from a massive hot, young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. This was captured mid last month from my backyard with my 102 mm refractor when we had a few days of respite from the wildfires’ smoke. It is about 4 1/2 hours of data. #explorescience #explorescientific102ed #asi533mcpro #zwocameras #optolong #optolonglenhance #asiairpro #astronomy #astrophotography #clayhausphotography https://www.instagram.com/p/CTcOTrjH4rY/?utm_medium=tumblr
