Description

This FOV spans the region north of Navi in Cassiopeiae to Sh2-183, the largest and brightest HII region on the left of the frame. The prominent and brighter nebulae near Navi are the two lobes of Gamma Cassiopeiae, the Ghost of Cassiopeiae. I am particularly interested in imaging expanses of HII across areas not dominated by popular nebulae.
