After photographing the supernova I took some time to look at the summer milky way and used CCDOPs ability to track and stack images to see if I could improve over my last image attempts. Track and stack does bad things to the image size, clipping the edges while stacking, which means my normal flats and darks didn't work. Resizing and editing the images meant converting them to 8-bit which affected the image adversely. Since then I've had access to CS4 which allows me to edit 16 bit files and ImageJ which can convert 16 bit fits to tiffs for use in Photoshop without loss. This has greatly improved the processing.
