Bubble Nebula

The Bubble Nebula, take… whatever

Every year I try and do a better job of capturing and processing the Bubble Nebula in Cassiopeia. Here’s this year’s attempt.

The Bubble Nebula is one of my favorite objects. Not only is it interesting scientifically (the bubble is the stellar wind of a hot O-type star blowing away the surrounding gases,) it’s also interesting aesthetically. WIth a little imagination, you might see a giant eyeball traveling through space, shooting out a flashlight beam ahead of it somehow!

It would be a really big eyeball however – that bubble is 7 light-years across! And it’s about 7,000 light-years distant.

Shot over 16 hours; the nebula is in the narrowband “Hubble Palette”, while the stars are in their true colors.
