Description

Despite its proximity to the Great Carina Nebula from our perspective, the open star cluster, NGC 3572,
lies only some 6,500ly away, putting it in the Carina-Sagittarius spiral arm of our Milky Way galaxy. (The
Great Carina Nebula, NGC 3372, lies some 8,500ly away.) The cluster (just below or south of the nebula)
contains hot, bright, young stars whose stellar winds sculpt the associated birth nebula into many
unusually shaped features, the most obvious being tadpole-like in appearance. The general shape of the
nebula, however, reminds me of a prawn!

This rather obvious nebula does not appear to have a standard catalogue entry. Its location in the
Carina-Sagittarius spiral arm is occasioned by much nebulosity, as can be seen here.

I have used a H+O triband filter in an effort to display the nebula’s features more clearly.
