The Rosette Nebula (also known as Caldwell 49) is a large spherical H II region (circular in appearance) located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy.
The nebula lies at a distance of some 5,000 light-years from Earth and measures roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see.
This image was shot using narrowband filters (Sulphur II, Hydrogen Alpha, Oxygen III) to produce this false colour photograph. Exposures were taken over 4 nights in February 2019 as follows:
44 x 5min Ha
83 x 5min OIII
113 x 5min SII
Total integration time 20 hours exactly.
