Description

Using my Bubble and Lobster Claw data from Sept 2019, I made a huge crop edit on NGC7538. This emission nebula is small yet quite bright. It is often looked looked over because of its popular neighbor, The Bubble Nebula. In this false-color narrowband image the warmer tones are Hydrogen and Sulfur, while the blues are Oxygen.
