The Bubble Nebula (NGC 7635)

A close look at the Bubble nebula in the constellation Cassiopeia.
This massive bubble (7 light years across) is formed by stellar winds blowing off the adjacent star which are moving 4 million miles an hour.
The Bubble is 7100 light years from Earth.

Lovely!! Impressive to be able to get 12 hours of acquisition, and 10 minute subs!! That pays off in details pulled put. Camera, telescope, tracker and processing are working very well for you!

Another beauty. So impressive what you’re able to image with your equipment.
7,100 years ago. Man!

Another stunning and inspiring image Dan. I think what amazes men most about these astrophotos, is the distance the light has traveled in order for us to even make a photo. What we are seeing is the past, the very distant past at that. Thank you, Dan.

Another fantastic image Dan. I know little to nothing about the constellations, nebulas, etc… but I can recognize a bubble when I see one! Just amazing.

So glad you’re sharing your astro photography with us here on NPN!
