Nicely done Doug. Gotta get that polar alignment right though. It makes all the difference in the world, 'eh h0ughy
What did you use to stack them Doug? Most of the stacking programs should allow you to rotate as well as translate to get everything aligned (unless of course the rotation is in each image

) If you don't have that option in your program you could alway lash out and get Registar for registering your images before stacking. You won't regret it
