The Rosette Nebula imaged from Chile.

Closely associated with this nebula is the open cluster NGC 2244 at center. These stars of the cluster having been formed from the nebula’s matter.

This giant molecular cloud is difficult to see even in large telescopes but photographs well. The open star cluster can be seen through a telescope.

Rosette Nebula is a large emission nebula located 3000 light-years away. The wind from the open star cluster has cleared a hole in the nebula’s center.

This image is part of the pro data set taken via the Telescope Live network. The remote telescope, an ASA 500N reflector, is located at El Sauce Observatory, Chile.

This a narrowband image, also known as the Hubble Palette. Light from the nebula was captured through H-alpha, Oxygen III and Sulphur II specialized filters.
