The Bubble Nebula (NGC 7635) is a glowing emission nebula in Cassiopeia about 7,100 light-years away. This image was captured with my Celestron Edge HD 8 using Antlia 3 nm narrowband filters over 9.5 hours of integration. It’s one of my favorite fall astrophotography targets and a beautiful challenge for deep-sky imaging.
Pacman Nebula NGC 281
To create the Pacman Nebula NGC 281, I shot 11 hrs of data and used a dynamic narrowband combination in Pixinsight.
