This shot is more or less centered on the Bubble Nebula in Cassiopia, with the open cluster M52 to its left and a concentrated emission nebula, NGC 7538, to its upper right. This image was taken at GMARS in October 2008 through the WO 80mm FD with an SBIG ST4000. Captured in Equinox Image and processed entirely on a Macintosh in Nebulosity 2.0, Photoshop CS3 and Leopard Preview. The challenge in this collection of objects was the huge differences in brightness.
