DSS data mega-mosaic of the Tulip nebula region featuring AA Cygni

I have been putting together DSS2 red and blue channel data (with a synthesised green channel courtesy of Noel Carboni’s Astronomy Actions) and got to this point before the computer started to give up with the mass of data. ┬áThis is the Tulip nebula region in Cygnus with the Northern Cross (open cluster) and “Red-Necked Emu” (open cluster) to the left. ┬áThe ultra red star near the top of the image is S-type star AA Cygni.
