In my opinion very doubtful. The position is easy to find beside NGC 2244.
But if I wouldn't know that this is a cluster, I wouldn't recognize it as
that. I saw a few bright stars in a quiet large area which are placed to
three different points. Thus they form a triangle. In the middle of the
triangle is a gap without any stars. With larger scopes and more fainter
stars the triangle may form a ring. Therefore I would describe the cluster
as very decentralized.
