►Rosette Nebula

Rosette Nebula, also known as Caldwell 49, is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, as the stars in the cluster formed from matter in the nebula.
The nebula has been observed to have a shape reminiscent of a human skull and is sometimes referred to as the "Skull Nebula". It should not be confused with NGC 246, which is also nicknamed the "Skull Nebula".

Next： Test of the new Optolong L-eXtreme F2 filter: Sadr and the Belly of the Cygnus. Previous：L-Ultimate Reviewer - scientist Ariel L. Cappelleti: Halos..., but at least in my personal opinion is not a great deal, for me is not a problem at all.
