Inside the Rosette Nebula lies the open cluster NCG 2244. The stellar winds from these stars produce the "hole" in the center of the nebula. Particularly noticeable, at the right, are the cosmic dust sculptures, most call them globules but I've heard of these particular ones called globulettes. At any rate, this telescope provides beautiful data showing the faint structures within the nebula, which are sometimes overlooked.
