The Rosette Nebula (Caldwell 49) is an HII region located in the constellation Monoceros. With a diameter of approximately 130 light-years, it's a prominent emission nebula situated about 5,000 light-years from Earth. This image was captured using narrowband filters (Hα, OIII, and SII), which effectively isolate specific wavelengths of light emitted by ionized gases. This technique allows for…
