OBJECT DESCRIPTION AND IMAGE SESSION

Commentary Globules are dynamic structures formed by cold molecular clouds and hot ionized stars. Typically the head of the globule face intense radiation stars and boils lower density gas and intense stellar winds. The winds are formed from the ionized stars that evaporate dust and gas away from the head. (*)

 

CG1 (aka Be135) is located one degree east from L Puppis (Mg 2.6 - 6.2). A Constellations that gathers others CG objects. The area is quite faint and the dust nebulosity was probably washed out by the Moon rising. It is quite visible some reflection nebula in the head of the object coming out of the group of stars which apparently are very active.  The image contains around 8000 stars.
