Nice one John - you've managed to bring out the nebula despite short subs / exposure. It's a bit limiting when they're unguided - I'm also taking unguided subs with my 200mm Newtonian. You should find that the flattener will tighten up all the stars nicely when you get it. I use a Paracorr on a 200mm Newtonian and it works very well.
