Rosette Nebula

“The Rosette Nebula (NGC 2237) A massive star-forming region of the Milky Way, roughly 5,000 light-years from Earth.

This image is a stack of one-minute narrowband exposures, captured from through a 250mm telescope on a star tracker. The narrowband filter isolates the hydrogen-alpha (Ha) and oxygen (OIII) wavelengths, allowing the camera's sensor to cut through the city light pollution to reveal the nebula's structure.”
