I can see some of the outer nebulosity appearing and the core is blown out. Maybe reduce your exposure to 120 seconds, increase your ISO to 800 and shoot about 40 or 50 of them. Also expose another 20 or so at 10 to 20 seconds to capture detail in the core. You can process these two exposure values separately in DSS and combine them in Photoshop to produce a dynamic range that reveals the dim and bright areas together that show equal detail.

Thank you, I am going to have to learn how to use DSSi think as all i have been doing is load in the darks, lights, flats and Bias frames and pressing process, there is obviously more to be done
