OBJECT DESCRIPTION AND IMAGE SESSION

Cometary 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 image deserves more exposure time,  however 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.
