Description

Hello! Meet the "Bubble Nebula" — the appropriately-named emission nebula also known as NGC 7635. If it looks like a balloon filled with air, it is because it is, kinda. At the center of the bubble is a star, who's solar wind is pushing against the nebula's red glowing hydrogen.

68 minutes of RGB color, plus another 92 minutes of Ha narrowband. I had planned to capture a lot more RGB — maybe I will someday — but ran into guiding problems.
