Hi Donald,
It looks like you are getting some good detail on the objects (Veil and North American). You also seem to be getting a strong central gradient in the images. I think this can be pretty typical with many optical set ups with even a nominal amount of light pollution. You can get rid of this by taking and calibrating flats. There are also some good programs (IRIS, ande an Astroart plugin comes to mind) to help get rid of this in processing steps as well.
