Description

The Bubble Nebula NGC 7635 is expanding with 28 km/s driven by stellar wind of a massive hot central star. While expanding the gas collides with surrounding molecular cloud. The interaction with that cloud forms the bubble.

This is a narrowband image (SII, Ha, OIII, cropped) with an Asi1600mmpro on a 130/910 mm TS apo refractor. SII and OIII were amplified and Ha was hold back to pronounce the structures on and around the bubble.
