The Rosette Nebula, registred under the number Calwell 49, is an H-II region in the constellation Unicorn. As it is not a very well-known or easily identifiable constellation, so we start from Orion to locate it. It is east of Orion, in the extension of the line formed by Meissa (Lambda Orionis) and Betelgeuse. There are several entries from the NGC catalog:
- NGC 2237: the western part
- NGC 2238: another part of the nebula
- NGC 2244 (= NGC 2239): the cluster open in the center
- NGC 2246: another Rosette emission region
